The 2A Armament AR10 Full Mass Carrier (FMC) was designed and manufactured as a high-quality, full mass bolt carrier group for LR-.308 DPMS style rifles. We manufacture the carrier and bolt in-house to ensure fit and function.
NOTE: Does not support the use of forward assist. This BCG is compatible with full auto weapon systems.
COMPATIBILITY NOTICE: Some 3rd party skeletonized upper receivers have the bore surface compromised that the bolt carrier slides on. 2A Armament does not recommend the use of these upper receivers due to a non-continuous slide surface that can cause binding and cycling related issues. 2A Armament cannot guarantee flawless fit and function in a 3rd party skeletonized upper receiver.
