CMMG Fastback Receiver Extension Listing ID: 3096578

This is a OEM Fastback buffer tube and stock from CMMG, came with my Mutant, but is not my cup of tea, comes with buffer for MK47 wich should work with any 308, if you want it for a normal AR15 you only need a buffer weight of the size. Brand new this part is $249. Only asking $120.
