TF Magazine Extension for Colt SMG +10


Product Description

PCC competitors rejoice! 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 -- we've had good luck with IWI and Brownells in particular
  • Extended springs available soon for C-Products and similar short-spring models.

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.

Not shipped to CA.

    I used these with the Wolf +10 springs and they worked 100% without any need for adjustment.
    I did use a screwdriver to secure the base to the magazine because I did not feel there was sufficient tension when if was just finger tight. I tried one with the factory spring initially and there did not seem to be sufficient pressure and I had a failure to feed. I added the Wolf spring to both and havent touched them since. I just shot a match in 30-40 degree weather and neither skipped a beat.
