Includes a full-auto lug for compatibility with registered full-auto lower receivers. Even in semi-auto rifles, the added mass improves function under rapid fire.
-
Properly staked and chrome-lined gas key prevents gas leakage, loosening, or failure—meeting strict mil-spec standards for performance and safety.
-
Available in finishes like black nitride, nickel boron, Parkerized, DLC, and chrome, offering superior corrosion resistance and reduced fouling.Rare Breed FRT 15 E3 Tripper

Each unit undergoes HPT (High Pressure Testing) and MPI (Magnetic Particle Inspection), confirming structural integrity and long-term durability.
Legal Status
