AR15 9MM MAG WELL ADAPTOR FOR COLT / UZI STYLE

This was my third 9mm magwell adapter. Great fit and quality, although I checked my first magwell adapter the other day to find the set screws were backing out. I re-tightened them and used some blue locktite. I did the same on my last one to find that Palmetto placed an out of spec bolt release in the lower. The people at Palmetto must have forced the bad part in making the KAK part fit too tight and it bowed, not allowing the mag holder to work. I replaced the bolt hold open and went to take the screws out that I had blue locktited in the Kak magwell and the screws were very easy to strip out the allen head. I would like to see Kak put larger set screws and a tighter fitting allen wrench in future product. It works well now but a lot of screwing around.

I did have some issues with Failure to Ejector initially upon first firing but after a closer inspection I realized that the ejector was not making contact with the round casings. So I got some pliers and bent the ejector inwards a little and that did the trick! ASC mags fit nice and snug, I did have to file the edge of the ASC orange mag feeder as it was catching on the front of the KAK adapter when it got down to one of two rounds causing a failure to feed, after I did that it has been running great! I was expecting to make some slight modifications from what I've read online since an AR9 is not a standard platform and the problems were easy to fix. adapter sits perfectly and is nice and tight but easy to remove if and when the time comes.

I bought this adapter to replace a lesser expensive block adapter and i should have bought this KAK brand from the get go, at first i had a bit of trouble getting it to fit , so i called KAK and they gave a few ideas to try and i ended up using my dremel to make a small adjustment and i got it to drop in with out a hitch, my nephew helped me get it to seat right in the magwell and he fastened the set screws and i test fired it today 5 11 19 and it ran very well with the exception of 2 malfunctions but i was trying different ammo, the 2 rounds i had a problem with i stopped using and i did not have a problem the rest of the day, so in closing if you are looking for a great 9mm dropin adapter block KAK is defintely the way to go for the money and reliabilty plus the last round hold open latch worked perfectly.

Not the most expensive...But fits like a glove. Fits the lower perfectly. I have a dedicated 9mm lower and other regular lowers. This is way cheaper and I don't have to buy another lower for a pistol caliber AR. Mags lock up tight and drop free. I will buy more.

Works like a charm, good price, good quality. I did have bend the ejector down a bit, but I'd expect to have to do a little tuning on any of the adapters.

I originally purchased a competitor's two piece magazine insert. I could not even reliably cycle the bolt by hand without double and triple feeds. I wanted an insert that was easily removable to convert back to a rifle caliber AR. Even Colt uses an insert on their dedicated AR 9mm platform that is affixed by two roll pins. I liked the fact that the KAK insert uses a bolt hold open that works with a standard AR15 bolt catch. It does hold the bolt open on factory Colt magazines that I had for my Colt 9mm carbine. Loosen two set screws and remove the top screw and it will slide out. I had purchased a Spikes Tactical 9mmX buffer. On my first trip to the range, I did still have some issues. Believing it was due to the length of the buffer, I replaced it with a standard length 9mm buffer. I also polished off the feed ramps a little bit with a Dremel tool. Today's trip to the range I ran hollow points and ball ammo with not one malfunction and 100% lock open with the Colt Mags. I couldn't be more pleased. The first day of shooting when I had lock back and a few feeding issues, I sent an email question to company. It was a Friday evening. I wasn't expecting an answer until the next work week. I received an email back from the owner within a half an hour. Very impressed with the customer service.

Great fit, well-made, very affordable. I liked it so much I bought a second one.

Why would anyone attempt to re drill to match holes or drill and install a 2 piece mag well adapter when this product is available??? It’s absolutely perfect for fit, finish and quality. Although I haven’t put it to use yet as in slowly gathering up bits and pieces, I have no doubt this will function flawlessly. Well done kakindistry for offering this ingenious product.

Even without instructions this was a no brainer installation, the magazines slip in and lock without difficulty and feeding has been positive with the limited shooting I have done so far. The unit is used in a pistol build which has turned into a fun project. I use Colt mags to match my Colt AR 9mm.
