AR15 9MM MAG WELL ADAPTOR FOR COLT / UZI STYLE

mag adaptor works very well

Mag lock works great and fits great. Could be steel but aluminum is fine. Only complaint I have is the set screws that tighten the block to the frame are too small and stripped out as soon as you try to tighten them. Need to be bigger

I was originally going to get the Promag and save some $ but this is worth the extra cost. Well made and solid. There is a slight vertical movement when installed but I think it could be from my mag release or possibly be design to account for variances in different magazines. I used an ASC 32-round and two Metalform 32-round mags for my first 250-round range session. Out of 15 total mag loads (didn't always load a full 32 each time), I had 8 perfect mag runs meaning no feed issues or last round bolt hold open issues...perfect. But I did have 7 mag issues where the last round would smash into the feed ramp and the projectile would push into the case. I don't think this is a mag well issue but magazine issues. Still pleased with this mag well adapter.

Everything exactly as advertised...quick delivery.

This is a very well made part. Even though the price may seem a bit high, it's a great value for the price, especially when comparing it to the price of other similar products on the market. It was very easy to install. It slipped right into the top of the mag well and seated firmly when pressed all the way down. Tightening the two set screws at the bottom of the part holds it securely in place. I haven't had a chance to test it yet, as I'm still in the process of getting other parts to complete my 9mm AR. But, I expect it to function well, given the obvious quality of the part.

Built a carbine for myself and showed a friend you liked it so much had me order another adapter for him to build. Function and fit are every thing we expected. Thanks for a great product that works as advertised.

Did an 8" 9mm AR pistol build 3 weeks ago and decided to go with the magazine block style because I have a few 80%'rs lying around already. Searched high and low on the interwebs and after reading the comments on this particular mag block I decided this was the best product for the least amount of money. This thing works great, drops in from the top and I did not have to make any adjustments to install. I do recommend using a dremel and polishing the feed ramp, but it is not necessary, although it will reduce feeding problems. Another thing to note is that it is definitely picky with magazines. Took it out yesterday and the parkerized steel ProMag magazine I have gave me some feeding problems. I would shoot about 4 rounds and it would fail to pick up the 5th. No jamming or stovepiping, but I would have to eject the mag (which ProMag steel mags don't easily slide in and out, they are slightly too big and must be forced in) and re insert it and rack the next round. Metalform mags had zero problems and it ran like a champ. With ProMag steel mag, LRBHO only worked about half the time as well. Not really the mag blocks fault but I think potential buyers should know it doesn't really like the cheaper mags. Over all, great product, they are half the price and just as good as the Hahn mag blocks.

Want to state up front - #1 This is my 2nd AR build & #2 haven't shot it yet. I have done lots of research though. I've read blogs, reviews, watched YouTube videos, looked at every mfrs. products - read the reviews there, and about the best price/quality seems to be KAK. Little hard to get. You have to wait till they're in stock. Seem to be very well made. Comes in from the top, held in place by a screw washer that catches on the top of the well. Then when you put the bolt release in -- it holds it in. There is a little play in the magwell but that I think is to be expected. I don't think you'd want to have to hammer it in. I was tempted to try to put some set screws in to hold it firmly but I want to see which direction they should come in from. I got a 32 rd mag from Primary and it fits great, locks well. Drops out when you hit the mag release. And you can visibly see that the bolt hold open is going to work by where the follower in the magazine pushes the bolt release is moved to the 'open' position. Obviously not firing it I can't verify that but it sure looks like it's going to work.

Couldn't be happier with this product. Easy installation, tight fit on a Aero Precision lower. Also purchased the 9mm buffer. Shot the build today and absolutely flawless. Shot both new factory and two different hand loads, all three fed smoothly. Thanks for a great product.
