9mm/40 magwell conversion - American Tactical Imports AR-15 Mag Well Adapter, 9mm, Glock

Fits a little snug but functions well. The only thing is that when I try to release the magazine it sticks and you have to manually remove the magazine. I would recommend this magwell adapter just need to get the magazine to release when you push the release button. Maybe use some kind of lubricants to maybe break it in.
