This extension adds a full 10 rounds to your 32-round Colt SMG-type magazine.
Adds +10 rounds, reaching 42+1! – Easy thumbscrew-and-gasket disassembly (no tools, unless you want it SUPER secure)
CNC machined from billet aluminum – Works with many «stock» mag springs
NOTE: Colt SMG mags come from many different manufacturers. Colt offered at least two major types — one where the floorplate slides on from the front, and the other which slides on from the rear. Our extensions are built to work with BOTH the front-mount and rear-mount styles. No matter what type you’re starting with, in all cases the TF retention screw should end up on the BACK of the magazine.
