Kns Non-rot Trg/hmr Pin.1555 G2

The KNS Non-Rot Trigger/Hammer Pin .1555 G2 from KNS Precision is a high-strength stainless steel takedown pin engineered specifically for the severe recoil and impact cycles of full-auto and semi-auto rifle platforms. Built to withstand the unforgiving duty of suppressed 9mm, .223, and 7.62x51mm weapons, this generation 2 pin design represents a critical upgrade for any operator running an M16, AR-15, or compatible platform where mil-spec pins would fail under sustained automatic fire or hard-use conditions.

The pin features an 11 inch-pound maximum torque specification with an 8 inch-pound recommended installation torque, providing a balance between secure retention and reversible disassembly. Constructed from stainless steel with either black nitride treatment (black finish) or DuraCoat protection (all other color options), the KNS G2 pin delivers superior corrosion resistance and dimensional consistency compared to standard MIL-SPEC alternatives. The precision-ground geometry eliminates rotational slippage during firing cycles, preventing the hammer and trigger pins from walking and causing weapon malfunction during critical moments. This is not a cosmetic upgrade—it directly addresses a documented failure mode in high-round-count rifles.

Operators, armurers, and law enforcement personnel managing rifles in duty or training roles will find the KNS Non-Rot Trigger/Hammer Pin essential for platforms subject to continuous automatic fire, suppressor-induced back pressure, or high-velocity ammunition. The .1555 diameter specification ensures compatibility with standard AR-pattern and M16 receivers while delivering measurably stronger performance than factory pins. Field testing confirms that this upgrade eliminates the pin rotation problem that degrades trigger reset and increases malfunction risk on worn or heavily-used receivers.
