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. This Full Mass bolt carrier group includes in house manufactured bolt carrier body and bolt for the same high quality, reliable performance that is synonymous with the 2A Armament name.
NOTE: Does not support the use of forward assist. Is compatible with full auto 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.
