9mm Adapter and MP40 Stock Kit – American Tactical

Still waiting patiently for the next batch of SBR stocks.

Please read before purchasing, not impressed with the alignment & acceptance of glock mags. Fits very tightly, scratches the mags in 2 spots, sometimes dosen't line up correctly with ejector, I had to use a dremel to smooth out burs to run smoothly. Also not a fan of the cheap coat hanger LRBHO. It works but…..only 70% of the time or (until it bends) who knows?? Finally the worse part of all! and in my opinion the worst engineer flaw of all!! The mag release is on the left side of the ATI 9mm adapter. Any of you that know glocks & have had them for years know all the older generation glock mags have the mag lock on the right side. Therefore the ATI conversation WILL NOT WORK WITH OLDER GENERATION GLOCK MAGS! you must now purchase new GEN 4 mags with the (slot) mag catch/release grooves on both sides. Needless to say if I would've known that I was gonna have to purchase new mags I would've either went with the colt adapter or just went with the better made product from STERN. So in my honest opinion the only upside to this adapter you dont have to lock in set screws, tighten bolts, or put pieces together. Do your research more than I did before purchasing. Hopefully this helps someone.

anyone else laugh when shlomo appeared in the background? haha

I think you need a bolt cut specifically for Glock magazines, you can't just use any Colt pattern 9mm AR bolt

Is it just me or does the stock fold at the wrong angle

I dig that magwell block
