The MOA Customs AR10/308 Carbine Buffer is a necessary component for shooters wishing to use their AR-15 carbine stock on their .308 platform rifle. Full sized AR-15 buffers are too-long for AR-308 bolts to properly cycle, but this heavy (3.8 oz) shortened buffer (2.5″ long) allows for reliable cycling!
NOTE: For use with MIL-SPEC or commercial AR-15 carbine buffer tubes only. This buffer will not function with rifle (A1/A2) or GI 8″ receiver extensions.
Modified AR-10 buffer spring is recommended for maximum reliability.
