Description The  enhanced  bolt  carrier  is  designed  to  reduce  carrier  tilt/cant  during  recoil  and   increasing  reliability  by  strategically  relocating  key  bearing  surfaces.  The  enhanced  carrier  has  fewer   points  of  contact  resulting  in  less  friction  area  and  the  slight  increase  in  carrier  mass  extends  dwell   time  and  ensures  proper  gas  pressures  for  reliable  extraction. • Material:  Case  Hardened  8620  Steel • Finish:  Black  Nitride.  This  advanced  low  friction  coating  minimizes  the  need  for  lubricants.
