WTS: used, chrome lined, Colt mfg. 11.5" lightweight profile barrel. This barrel was pulled off of one of the Colt Commando barreled uppers that CMMG sells. Please note that the barrel is used, the FSB does not have a bayonet lug, and that the flash hider, crush washer, front sight, front sight detent, detent spring, gas tube, gas tube roll pin, delta ring, handguard ring and spring assembly are not included. It's a stripped barrel with barrel nut, handguard cap and front sling swivel. It's in good shape, but the parkerized finish is sort of mottled in color. It'd be a great barrel to refinsh to use in a XM177 retro project. Price is $185 with PAYPAL or certified funds shipped to your CONUS address. Barrel is marked C MP CB .
