AR15 9MM MAG WELL ADAPTOR FOR COLT / UZI STYLE

The only issue with this block is that it will not fit a Wilson combat lower but fortunately I had a spare Anderson that it for perfectly. My reason why it's not 5 is that the screws do not have great contact since they are so short. Otherwise a good product

Works great and easy to install

Fit was nice and snug to an Anderson Lower.

So far it has worked great! I have it in a Silencerco lower and it was extremely tight to get in. But a little rubber hammer, with gentle taps, slips it right in. Two set screws for added security and it’s good to go!

Haven't had a chance to take it to the range but based off of overall product and customer service I recieved i will be ordering from KAK again. Shipping was fast, and install instructions were included even though it's pretty self explanatory, but it was nice to have them included.

The first mag adaptor that I recieved from KAK was too tight to fit in an Anderson lower. After discussing the issue with Chris the block was exchanged for a new unit but it was still too tight. After removing about .004" combined from the leading and trailing edges the fit in the Anderson lower was nice and snug---could be installed and removed with finger pressure. I took the finished rifle, KAK 9mm 16" barrel, Anderson lower with KAK mag well adaptor. and C-Products Colt style Duromag to the range yesterday and had no FTF issues! The product worked perfectly after the initail triming of the front and rear of the block. I really like the feed ram idea on the Colt style blocks, it definitely helps to eliminate feeding issues. I have a dedicated Glock lower and it has feeding issues, mainly becssue of no feed ramps and also the Glock and Pmag magazines are loose in the lowers mag well. On the contrary, the Colt style magazine when installed in the KAK mag well adator is a nice snug fit but drops our easily when the mag relaese is activated.. Thanks for the nice product.

Received in good order, Would not go into PSA lower so I used an Anderson. It was a tight fit. Ordered Pro Mag 32 and 25 mags which took some modifying to drop free. Metalform 32's drop out beautifully but jam when cycling dummy rounds. Haven't tried live fire yet but will soon. I'll update review afterwards. So far I am pleased.

Bought two of these an could installed both in the same lower, could tell that there was a noticeable different in how tight one was over the other. Tried the looser one in a different lower and it absolutely would not fit.

Initially a bit worried as, it fit as tight a a scotch mans purse. Tried several lowers before I found one it liked, kinda like college roommates.
