Gen2 ProMag 9mm AR15 Adapter block install

In this video, I will install the Gen2 Pro Mag 9mm AR-15 Magazine Adapter Block (PM237B) on a standard mil-spec lower.
This adapter requires no modification to the lower and no tools to install or remove. It allows you to use colt smg style magazines on a standard 556/223 lower receiver.

    Long shot question seeing that this vid is 3years old… will this adapter work with Glock mags?

    Have you shot any with the Pro Mag adapter yet? How well does it work?

    I have a pro mag adapter like this and the round feed too low into the back of the barrel. The feed ramp is too low it bounces the bullets off the back of the barrel before they go in the chamber and occasionally drives the bullet back in the case and I have had the bottom of the case blowout because the Bulge created at the base of the bullet when it’s driven back into the case and short Chambers. The feed ramp does feed into the chamber it feeds into the back of the barrel . the bullet gets shoved back into the case and causes high pressure and blows the bottom of the case out

    You didn’t put a link

    So this allows you to have the 9mm mag well that has a bolt hold open and drops the mag from the normal mag release button?
