gas system. AR15 Profile BCG for 16" barrels with a mid-length gas system,
18", 20" and 24" barrels. These are general recommendations. Please call us
with any questions or concerns before you place your order.

Thank You, MAS Defense.

These are high quality BCG's. Not your bottom dollar 4140 grade steel. They
