Works Very Well 31/05/2018
Works well with C product metal form mags. Drop in is easy to take in & out if your swapping uppers. I did have an issue with the mag catch not poking out enough to grab the magazine. I went with a 9mm Mag catch and then had to take material off the base by the post. This caused it to can't into the wag well more with success. No fault of the drop in.
Great product 10/11/2016
I bought this to use in my SBR lower with a10.5" upper. Functions perfectly with metalform mags with 3 different bullet weights. Easy in and out in about 3 min. At the same time I bought a designated 9mm lower for a 7.5" pistol. Nothing but malfunctions using the same mags.
