If you are looking for reliability, well make and affordable solutions to your next AR build, BCM has a history of providing just that.
The classic BCM4 that you have known for a decade. Built to near military specs, with white T-marks and gray interior lube, the BCM M4 is milspec forged and will fit almost any forged lower. BCM uppers are built a little tighter than most, to give you the best reliability. That means some heat may have to be applied to the upper to fit the barrel. Works with any AR15 or M4 barrel with an M4 barrel extension. Great for that budget build, or for your next military clone built.
BCM is known for its quality assurance. BCM sources materials from a number of suppliers and checks and double-checks products before they leave the shop.
Includes dust cover assembly and forward assist assembly. No BCG or charging handle.
Manufacturer's part number BCM4-UR-M4
