A set of the NM Adjustable RPS Trigger™, and the NM Speed-hammer.
National Match Prepped, this trigger/hammer are the only M1 trigger parts to ever offer drop-in NM performance, with no modifications or grinding required, along with a 25% reduction in lock time (hammer swing time).
Polished, ground, and fully hardened sear edges will release the hammer like breaking a glass rod. A hard / low friction surface coat makes the trigger pull butter smooth and eliminates wear.
All parts are true ‘drop-in’ on USGI spec trigger housings with no additional fitting, polishing, or tuning required on the parts or on the rifle. (Taiwanese trigger housings occasionally require some fitting)
Lock time is the time between when the trigger releases the hammer, and the hammer hits the firing pin. That’s time during which the rifle is typically swinging off-target. Especially in offhand shooting, if shots are broken as you are moving ‘off-target’, that time can cost points. The ShootingSight NM Hammer is machined from billet steel to be light weight, reducing polar moment by 40%, and optimizing geometry for speed. Lock time is reduced 35% from 8.5ms to 5.5ms; which is as fast as a mil-spec hammer on an AR-15.
Trigger sear edges are ground and polished to be sharp before an ultra hard and low friction surface coating is added. The result is a smooth trigger pull, and a clean break which will not wear. Adjustments are added for second stage sear engagement, as well as for trigger pull weight, allowing adjustment to a minimum of 4.5lb for NRA/CMP competitions.
