Hello all. Long time lurker, brand new member here! I figured I'd throw in my two cents on Bullpup Unlimited's stock since this is the place where I first found out about it. And just for complete transparency, I am not affiliated with, employed by, related to, or beholden to Bullpup Unlimited in any way. I just love bullpups and I love shotguns, so this was a great event for me!
Upon opening the box, the kit seemed a little flimsy. I was worried that it would warp or bend or even break, but as subsequent events showed me, these concerns were ill-founded.
Assembly was a little difficult at first. My kit was minus a few necessary screws and one of the Allen wrenches, but it was my good fortune that I have a hardware store across the street from me. Ten minutes later I had the necessary screws. The Allen wrench was easy enough to find since I have about fifteen billion of them lying around from all the other kits, scopes, accessories, and other gee gaws that came with free Allen wrenches.
The slide release button was too large, but since I had been warned about that in a mass e-mail sent out to all preorders, it did not catch me by surprise.
Once I had all the required parts, assembly was easy and took about half an hour. Keeping the parts together while screwing things together can be a little difficult, but nothing you can't do alone.
Once assembled, the gun feels rock solid and looks bad-@$$!
But as mom always told me, looks aren't everything.
After assembly, I racked the slide and dry fired it a few times to test its fit and function.
The slide worked well and didn't hang up at all. It's obviously not as smooth as an unmodified 870, but just barely. I hardly noticed the difference.
The trigger is not as bad as some bullpup triggers, like the Bushmaster M17s, for example. It obviously is a little mushier than an unmodified 870 trigger, but I found its function to be more than acceptable.
Balance was great.
And the side-mounted rails are positioned perfectly for lights or lasers if you are so inclined to put those on (I put on a light and am thinking about putting on a laser for reasons I will explain below).
So it not only looks good, but feels good and works well to boot.
Now on to the range.
The gun I put into the kit was a Remington 870 Tac Desert Recon with an 18" barrel and 2-round factory extension.
Ammunition used as a mixture of Fiocchi, Federal, and Winchester. All of them were 2 3/4" and all were buckshot. The Federal was low recoil, the others were regular loads. I brought a total of 60 rounds to the range.
I didn't bring a camera, so unfortunately there are no pictures.
My conclusion after firing the gun for about 40 rounds (three other friends also tried it on for size): it's a great conversion kit.
Recoil was noticeably reduced. Full power loads felt like low-recoil loads and the low-recoil rounds felt like nothing.
I had one short-stroke during the entire time, so remember: really work that slide. Don't be scared to pump it like a regular shotgun. Do that and you'll be fine. Treat it with kid gloves and you'll get hung up like I did. I told my friends to keep that in mind and none of them had any problems.
Speed was not an issue. I tend to fire slow and steady, but one of my friends decided to see how fast it could go. He loaded up five rounds of Federal 00-buckshot and emptied it in about three or so seconds (I didn't bring a timer or anything like that).
The only issue was that the gun tends to shoot VERY LOW. So if you have a scope or red dot on it, you're going to have to crank that sucker as far as it'll go to get it sighted in properly. My red dot was not able to compensate for the difference between my point of aim and the actual point of impact, but it's a cheapo $49 red dot I bought at a show, so I wasn't too concerned about that.
The MagPul MBUS sites I had on it were of no help on elevation, but did keep my shots centered. So if you find yourself with nothing but iron sights and some screaming meth head is coming at you with a meat cleaver, aim for his head and you'll hit him in the chest. A laser mounted on the side and zeroed in would probably help rectify this problem.
After forty rounds, I felt no soreness in my shoulder at all. Normally I would feel it for at least an hour or so, but this time there was nothing.
It's worth the money. Putting it together can get a little frustrating at times, so if you're not mechanically-inclined, have a friend who is put it together for you. The kit shoots low, so keep that in mind when sighting in any scope or red dot. The kit itself adds a negligible amount of weight that is more than offset by the better balance it imparts and the reduced felt recoil it offers.
In conclusion, this kit is like having a hot super model secret agent for a wife: she can shoot and looks damned good doing it.
I highly recommend it. TDog says check it out.
