Really cool kit, well thought out and easy to assemble.
I put this on a IAC Hawk 981R works great. slight lag in the trigger but with this sort of kit I dont see any way around it and its not bad.

Ive seen people say it wont work for lefties but the port is far enough infront of your face and with the deflector a leftie could use this no problem.

And lastly, to get the four long screws by the handle its much easier to remove the pistol grip to run those in.

My 870 went in flawlessly. Have put 200 rounds through it. I lubricated everything inside and out. Mainly because of some other reviews I was reading. For me it works like a charm. It is true that it takes about two boxes of ammo to get it properly broke in. It still was shooting fine but wasn't butter smooth like it is now. That should have been expected from many of reviewers. I added an 8 round mag extension. No need to over tighten it. I left my original barrel on it. Gun was shooting high due to shortend overall length and raised rail. I put a magpul pop-up front sight on rail and it shoots perfect. no need for back sight. Added single point sling this thing rocks and runs great. .Your only limited by your imagination and willingness to use it for what you could put on this thing. It really is fully customizable! And adjustable! If you tighten slide down to tight, then back it off a bit. Don't review and say it terrible. This is a great quality product to start. But we make it better!

I found the BullPup Unlimited kit to be well made and easily installed. When I first opened the box I thought that the plastic might not be sturdy enough for the task at hand BUT, after completing assembly and firing I found the combination works like a champ. Having never owned a bullpup configuration firearm I found this one to be easy and fun to shoot. All of the functions, safety, slide release, pump action worked as advertised. My lack of experience with disassembling pump guns makes my only suggestion that the buyer insure that He/She has a forend wrench available for the removal of the 870's forend. I'm very happy with my purchase from 'Bud's Gun Shop' !!!

its a novelty item. the bu870 is well made but feels cheap due to their trigger. but you get to cut off 10 inches without the need for a tax stamp.
