KNS Gen 2 Mod 2 .154 Dia Non-Rotating Trigger / Hammer Pins Flat Dark Earth
Kns Precision
The Kns Precision .155" Gen. 2 Mod. 2 Non-Rotating Pin Set delivers a clean, low-profile trigger pin upgrade for AR-15 builds that demand precision and minimal receiver footprint. These oversized .155" diameter pins are engineered to eliminate pin rotation—a common source of inconsistent trigger performance—while the Gen. 2 Mod. 2 design keeps links pulled tight and pinned geometry stable shot after shot. If you're tuning a match rifle, precision rifle build, or simply want tighter tolerances and more predictable trigger behavior, non-rotating pins are a smart, inexpensive upgrade that transforms how your trigger performs under fire.
The Mod. 2 variant features ultra-low-profile links that sit closer to the receiver than standard sets, making them ideal if you're working with a tight-fitting lower or want to minimize any protrusion. The .155" pin diameter is larger than the standard .154" option, taking up tolerance slack and locking trigger geometry in place. This sizing also fits standard pin holes—no gunsmithing required—making installation straightforward for anyone comfortable doing basic AR maintenance.
Kns Precision has built a solid reputation among serious shooters and gunsmiths for trigger reliability and innovation. These pins are a no-nonsense, mechanical solution to a real problem: as your lower reciever ages and pin holes wear, or as temperature and recoil cycles your trigger, pins can migrate and rotate, degrading trigger feel and consistency. Non-rotating pins simply stop that from happening.
