Including a couple of aftermarket equipment enhanced the KS7’s versatility and lower recoil considerably.

When the KS7 shotgun first arrived from Kel-Tec, I gave you my first impressions after unboxing and working some dry hearth drills for a pair days with it

A pair vary journeys adopted throughout which I ran just about each sort of shell I had in my ammo drawer, from mild goal hundreds to heavy 00 Buck self protection hundreds, from 1.75” shells to three” magnums.

The gun ran greatly. Though the parents at Kel-Tec stated they may vouch for its reliability feeding 1.75” shells like they do with the KSG, I had no actual issues with them, however extra on that later.

In brief, I actually dig this little gun. I sort of really feel prefer it’s the right shotgun for a complete host of functions, chief of which being self and residential protection. I say “sort of” as a result of it hasn’t confirmed itself over a protracted sufficient time interval but, and since I haven’t gotten it actually cruddy or soiled but.

However, because it stands, if it had a choke tube adapter, I’d completely turkey hunt with it and the teams I acquired with 1/4 oz. slugs show it’s greater than able to taking a deer inside 50 yards.

It truly is every thing I beloved in regards to the KSG, however slimmer, lighter, and extra nimble. The simplified design, which cuts the general capability from 14+1 within the KSG to six+1 within the KS7, makes the gun simpler and extra instinctive to function. I simply actually dig it.

However, that doesn’t imply I didn’t wish to do a couple of issues to it. Let’s be actual right here.

Buying and selling the Carry Deal with for a High Rail

I did have some points with the gun itself after spending a while on the vary with it. The massive and distinctive carry deal with/integral iron sights meeting was simply…cumbersome. It’s extraordinarily mild polymer, so it didn’t actually add weight to the gun, simply a variety of pointless peak. It would make the KS7 appear to be a gun from Aliens, however it needed to go.

The most effective and easiest various I discovered looking out by means of the comparatively small quantity aftermarket elements for the KS7 was the “Prolonged Precision Picatinny High Rail” from Hello-Tech Customized Ideas

Curiously sufficient, the holes on the highest rail from the KSG line up with the mounts on the KS7 and people on-line have stated you’ll be able to swap it from one to the opposite, however the screws affixing the rail to my KSG should be secured with Purple Loctite, as a result of they weren’t budging.

Regardless, the KSG rail is 12.25” inches lengthy, whereas the Hello-Tech rail is 15 inches, and since I deliberate to make use of iron sights on the KS7, an extended sight radius was additionally engaging to me.

The carry deal with got here off the KS7 simply and the identical two bolts and washers are used to affix the brand new rail from Hello-Tech. Easy.

It dramatically shrank the gun’s profile and made it really feel extra nimble and compact, although it added an oz or two.

However a very powerful factor is now, I can use no matter irons I need or placed on a pink dot or any sort of optic. It’s a little bit of versatility that, in my thoughts, the KS7 ought to have as an possibility.

Is the carry deal with helpful? Sure, it really is. The KS7 is a tiny gun, and maneuvering it round with out holding the grip and whereas being conscious of your muzzle is made a bit simpler with the deal with, just because there aren’t too many locations to seize the gun — and the iron’s are completely high-quality, I really like the brilliant inexperienced entrance sight fairly a bit. Plus, it provided areas to connect M-Lok rail sections or equipment, which I attempted, and it did work, however having a light-weight or laser unit up there felt awkward.

However for what it’s and what it affords whereas limiting the optics I might use on the shotgun simply didn’t add up for me.

For additional testing, I put in a beefy set of irons with an adjustable rear peep sight I discovered in my elements cupboard — the origin of which I can’t recall, however they had been good and I’m positive any folding or mounted irons can be greater than enough. I sort of wish to experiment and see how nicely it factors with only a entrance sight, appearing sort of like a bead sight.

The following factor that needed to be addressed was the recoil of the small, mild shotgun. With goal hundreds, the inventory gun was as straightforward capturing as any pump gun. Issues didn’t begin getting uncomfortable till I began capturing 6 rounds of two.75” self protection hundreds. The three” magnums had been additionally sort of punishing, however they all the time are.

Rather a lot has been stated on the Interwebs about how terrible the recoil of this shotgun is, so I used to be ready for the worst — however all in all, I discovered the KS7 to be simply manageable and never worthy of the criticism it has obtained in that space. Nonetheless, it might’ve been a bit extra snug to shoot with the heavier stuff.

Hello-Tech additionally makes two completely different muzzle brakes for the KS7. The Howitzer 70 appears, because the identify would counsel, like a large brake on an artillery piece. I went with the extra streamlined Metal Defender brake which is tubular and surrounded with ports.

It’s CNC machined from 416 stainless and simply over 2 inches lengthy with a weight of 4 oz. Hello-Tech features a particular too that connected to a 1/4″ socket wrench so you’ll be able to take away the manufacturing facility barrel nut.

The journal cap needs to be eliminated so you may get the instrument on the barrel nut, in order that’s step one. It merely unscrews, however its underneath pressure from the journal tube spring, which is able to go flying out until you unscrew it slowly. You may need to wrap it in a material and use some pliers to get it began.

The barrel nut isn’t Loctited on, however it’s torqued down fairly good. The easiest way to take away it’s to safe the gun in a gun vise or pad a daily vise and lock it down. Be certain to clamp the receiver and never one other a part of the shotgun, as you may trigger the polymer elements to flex and weaken or snap.

The most effective and most secure method to do that is through the use of the KS7 Vise Block from M-Carbo, which is what I ended up doing to be sure to don’t find yourself damaging the shotgun.

As soon as it’s off, you simply screw the muzzle brake on, BUT, you’ll must put the magazine tube again collectively FIRST.

The bottom of the brake matches very carefully to the magazine tube cap and the fatter half really overlaps it. So sooner or later, to take away the magazine tube cap, spring, and follower, the brake should even be eliminated.

And partially because of this DO NOT LOCTITE THE BRAKE ONTO THE BARREL. There is no such thing as a want for this. Should you wrap an appropriately sized Allen wrench in tape and slip it by means of the holes within the brake, you’ll have greater than sufficient torque to screw it down tightly by hand and that’s the way it ought to be finished.

After a protracted vary session, simply be certain that it hasn’t loosened up underneath recoil, however mine hasn’t after 300 rounds, a few of which kicked fairly exhausting.

Whereas I used to be doing this step and had the magazine tube spring out, I figured I’d improve the follower with a high-vis orange one from M-Carbo, however I believe just about any 12-gauge follower will work.

That hopefully took care of some felt recoil on the entrance of the gun, now for the opposite finish.

I’ve had a Limbsaver Airtech slip-on recoil pad on my KSG just about since I acquired it, so I figured the identical answer would work nicely for the KS7, and it does. The form and contours match the gun aesthetically and nothing stands proud to get caught in your gear or folds in your clothes. It additionally provides somewhat bit to the size of pull, which makes the gun match me somewhat higher total and smoother to shoulder, however when you’ve got a smaller body, it’s one thing to consider.

The medium sized slip-on mannequin matches very nicely and doesn’t come off simply throughout common use, however if you need it to be safer for leaping out of a aircraft or no matter it’s you do, you may use some 100mph tape to safe it, or some double sided tape for a cleaner look. Plus, the traces of the pad match up fairly nice with the KS7’s buttstock.

I couldn’t fairly cease decking out the KS7 there. I added a 7-shell Velcro card service to the proper facet of the inventory, which is sweet as a result of it’s simply detachable when you don’t want it, leaving only a fuzzy Velcro patch.

I additionally needed so as to add a gun mild of some form to the shotgun so it will be prepared for a house protection set-up, however I had some hassle with this step as soon as I made a decision on the Crimson Hint Railmaster Professional combo mild and laser.

With the carry deal with gone, there are solely two M-LOK slots remaining on the gun and they’re on both facet of the slide deal with, however neither of them are secure sufficient for a laser sight to carry zero. So I grabbed the Mini Angle Rail that Hello-Tech Customized for the KSG, which mounts on the highest rail and gives a facet rail platform.

Due to the completely different form of the slide and motion bars, the rail can’t be mounted on the KS7 ready ahead of the set off like it may well on the KSG. Nevertheless, it can be mounted nearly instantly above the set off and pistol grip, which is the place it went. I’m capable of simply activate the laser sight/mild with the thumb of my capturing hand with out transferring from the capturing place and it doesn’t get in the way in which of something. Although the windage and elevation changes on the laser had been reversed as a result of the sight is mounted on the facet, I used to be capable of zero it fairly simply.

There was yet another little factor that needed to be added.

As I used to be perusing the choices for the KS7 from M-Carbo, I noticed they make an insert that fills the hole polymer grip on the KS7…one thing I needed to do the second I acquired the gun, however it additionally homes a single 12 gauge shell as a final ditch backup.

Whereas the end on the polymer insert is somewhat tough, it’s designed nicely and it stayed safe with a shell in it by means of a number of capturing and recoil, however was nonetheless straightforward to take away along with your fingers (with out nearly ripping off a nail). It’s somewhat gimmicky, however I prefer it just because it fills up that hole pistol grip, and also you don’t have to place a spare shell in there. You need to use it to retailer batteries, a small flashlight, or no matter you need.

The KS7 is a high-quality shotgun out of the field, let’s get that straight. It handles nicely, capabilities reliably, and has plenty of strong options along with some great benefits of being a light-weight, nimble bullpup.

And the cumbersome carry deal with is helpful and the sights it homes are completely high-quality. The one time the inventory shotgun was somewhat unwieldy or uncomfortable to shoot, in my view, was after a two-hour vary session and when firing a full magazine of exhausting kicking defensive shells or magnums.

I simply needed somewhat extra adaptability so far as optics and sights, and a spot so as to add a light-weight/laser, as I really feel it’s an vital characteristic on a defensive firearm — and I like capturing the factor, so I needed it to be somewhat extra Cadillac and rather less Econoline by way of consolation for longer days on the vary with packing containers of goal hundreds. Plus, the extra snug you could be whereas practising on the vary, the extra you’ll observe and the much less seemingly you’ll develop one thing nasty like a flinch.

That stated, the primary objectives of those upgrades had been to make the gun extra compact and to scale back felt recoil and muzzle rise — and people objectives had been finally achieved.

After all of the upgrades had been made, I instantly preferred the brand new rail and iron sights set-up after I acquired to the vary. The decrease irons on the rail let me get down on the shotgun with out that deal with getting for my part. It felt much more pure.

So far as recoil, the distinction was fairly exceptional. Hello-Tech Customized says the Metal Defender brake reduces felt recoil by as much as 30 %, and I’d must say, that sounds about proper. Mixed with the Limbsaver pad, the little shotgun turned an absolute pleasure to shoot, it doesn’t matter what I fed it.

I additionally needed to conduct an experiment with 1.75” shells. I acquired provide of Federal’s new Shorty shotshells in №4 Buck, №8 Birdshot, and 1/4 oz. slugs.

The gun kicked little or no with the small shells, they usually cycled nicely by means of a number of packing containers of ammo…and it’s not exhausting to undergo a field. You may match 11 of the Shorty shells within the magazine tube of the KS7.

Should you quick stroke the motion in any respect, it gained’t decide up a recent shell — which is the case with 2.75” shells as nicely (and is the case with the KSG), although it’s much less forgiving with the smaller hulls.

All the pieces appeared to operate rather well and I even shot a fist-sized group at 30 yards with the slug hundreds off hand.

However there was one bizarre prevalence. I loaded a complete field of shells — 10 rounds — in to the tube, however I solely fired 9 photographs. The gun was empty. On the vary I believed I mis-counted or had already grabbed a spherical out of that field earlier.

Solely when analyzing some video (above) my buddy shot of our vary session did we see what occurred. For some motive, the KS7 appeared to eject an unfired shell together with the empty hull of a fired shell on the identical time. After seeing the footage, I did recall selecting up an unfired shell from the deck after we had been policing our hulls. That’s not nice, however it didn’t jam and the set off didn’t fall on an empty chamber.

It’ll require some extra testing to see if I can replicate that exact drawback.

Total, with these upgrades, the KS7 is in regards to the excellent residence protection shotgun, and a fairly nice throughout shotgun.

I wouldn’t precisely belief it as a house protection gun loaded with 1.75” shells simply but, although that 11+1 capability could be very engaging.

Nonetheless, with 2.75” shells you have got 6+1 within the gun and seven extra rounds on the service, so 14 a great deal of 12 gauge 00 Buck on board, or no matter you select, is kind of formidable in a really small bundle.

Plus, from a house protection perspective, it’s vital to notice that the compact bullpup design means you’ll be able to really intention the shotgun with one hand — and never some shaky form of aiming and will perhaps hit one thing the scale of a automotive door aiming — however get an precise, regular sight image. And firing it one-handed doesn’t really feel a lot completely different than firing it two-handed. This may be stated of just about all bullpup lengthy weapons. The mass of the receiver is to this point again that it may well simply be balanced and the burden simply held with one hand.

Why is that this vital? Nicely, throughout a house protection scenario, although you must keep away from doing so in any respect prices, you would possibly find yourself transferring down a hallway or from one room to a different. Not solely does the quick size of the gun imply it’s more durable for a foul actor to seize it, the truth that you’ll be able to manipulate it nicely with one hand means you should utilize the opposite hand to do issues like open doorways or flip on mild switches with out decreasing your gun or being defenseless for a second or two.

Plus, when you can intention and shoot it with one hand, then you’ll be able to confidently maneuver it in just about any method with one hand.

The shorter gun can be a lot simpler to maneuver within the confines of a house or house whereas nonetheless offering the ballistic benefits of an 18.5″ barrel.

Take into consideration this…a KS7 is simply 26.1 inches lengthy (with out the aftermarket brake and recoil pad).

A 12-gauge Mossberg 590 has a capability of 8+1 shells, however it has an total size of 41 inches with a 20 inch barrel. That could be a big distinction.

Because the barrel on a standard pump shotgun will get shorter, so does the magazine tube, which reduces capability.

For instance, the Mossberg ATI Tactical has an 18.5” barrel, similar to the KS7, however a capability of 5+1 whereas the general size continues to be 36.37 inches — greater than 10 inches longer than the KS7 and holding one fewer shell within the journal, with the identical barrel size. That’s the benefit of the bullpup design.
