AR15 9MM MAG WELL ADAPTOR FOR COLT / UZI STYLE

Received this for my AR9 build, fit and finish looked good, dropped right in my Anderson Lower. Would have been nice if there were some instruction and the tiny allen wrench that fits the set screws, pretty minor issue tho. After 1 mag where it seems the rounds were sticking a bit on the feed ramps, it started running perfectly with no feed issues whatsoever. Using ASC mags, having issues feeding the last round, pretty sure it is an issue with the mags. LRBHO works when the last round feeds which was about 1/2 the time. Going to try a metalform mag. Mags drop free (ASC mags). I would highly recommend as an alternative to others that cost twice as much, would definitely order again.

When I first received the 9mm magwell, I was worried about the installation because the whole product seemed a little bent out of shape and non-symmetrical. It was a snug fit in my Anderson lower, but the magazines drop free and the shells eject perfectly. The price and quality cannot be beat, and I'm sure this conversion works just as well as the ones that cost twice as much. I would recommend this to anyone looking to build an affordable 9mm AR.

I originally wanted the glock since I had since I had a glock 19. You know save on magazine costs, have the PERFECT PAIR handgun and rifle that have interchangeable mags. ended up not liking the glock and gave it to my brother. Back to the review, the insert is very easy to I stall, works like a charm and it doesn't break the bank. My favorite part about thing about the mag well insert is waiting g for the the last round to eject and having the bolt lock back, ejecting the mag, slapping in a fresh one, just pressing the bolt release and you are ready to go again! LOVE IT!!!

Worked flawless from the start with modified uzi mags, great price and shipped fast, thanks

This is a great magazine adapter. However, there are a few things you should know. ASC magazines did not work at all with my setup the feed lips would not let the bolt to pass through without hanging up. I am using metalform brand magazines and they fit much better. The mag fits snugly in the adapter block and locks in and drops free easily. When cycling rounds by hand I was having frequent misfeeds. I hand polished the feed ramp on the block and polished the opening to the chamber on the barrel and this completely resolved the issue. I put 200 rounds through it yesterday at the range with no issues at all. I am running a KAK 8" value line barrel.

I bought a CMMG 9mm dedicated lower, but I didn't want to wait the 7+ months to SBR it before I could put an 8.5" barrel on it so I bought this mag block for my SBR'd 5.56 lower and put my shorty upper on it. LRBHO works perfectly, it ejects reliably and it is very solid, no fear of it moving around. The only issue I've had with it that I didn't have with the dedicated 9mm lower is that if I use the mag as a monopod, sometimes the gun will malfunction, but this is for USPSA PCC division so I'll never be shooting like that anyway. All in all I highly recommend this product as an alternative to a dedicated lower.

I purchased this mag block adapter for my 9mm AR build. After searching on the web and coming up with many other similar products being out of stock, I settled on KAK industries product. I am pleased with the quality & the fact that it was in stock when ordered. I did have some feeding issues that were later resolved. For my build the metal form brand magazines worked better than the ASC brand magazines. Thank you KAK industries.

well made very good tolerances snug fit Asc magazines wouldn't feed the last round modified uzi and metalform did 3 things that I think should be done to improve Instructions with parts breakdown, polish the feed ramp make the set screws 1 size bigger

All metal construction also well constructed, and work flawlessly in my build. Fast shipping, easy of ordering, and amazing service what else can I say.
