The Geissele Hi-Speed Service Rifle Trigger is designed for NRA High Power Service Rifle competition.  It is an approved trigger for use in CMP sanctioned competitions such as National Trophy, NTIT and all Excellence In Competition matches.

The Geissele Service Trigger includes all the Geissele standard features:

•  Lightning fast lock time
• Separate sear adjustment for a sharp 2^nd stage
• Independent 2^nd stage weight adjustment
• Overtravel adjustment
• Wire EDM cut sear surfaces for a smooth, precise pull

Service Rifle competitions require military based weapons that meet certain criteria, one of which is a minimum trigger pull of 4.5 lbs.  Our Service Rifle Trigger includes our exclusive 5-Coil trigger spring which will give a nominal 4 lb 1^st stage.  The Service trigger pull weights are biased with most of the pull weight on the 1^st stage; this will allow a light second stage with an icicle sharp break, effectively giving your weapon a match grade trigger let off.

*NOTE: Colt receivers with large pins (.169" dia) require our Large Pin Trigger.  Our Large Pin Trigger will not work in a lower that has a Sear Block.  Some early Colt receivers and all other branded receivers (Bushmaster, Armalite, Rock River, Olympic Arms, Eagle Arms, PWS, Stag, CLE, etc) use the small pin (.154" dia) that our Small Pin Trigger is designed for.
