AMMO,
The only way to eliminate any amount of creap is to make the trigger adjustable.This should be done by someone who knows how.
If you do it wrong you'll buy another trigger or worse.Keep 1 thing in mind.Most,if not all military rifles are (and will always be)a 2 stage trigger.
The only way to get away from a 2 stage is to buy an aftermarket such as Timney,Shilen,etc.
Yes,I know they're not available for the M14-M1A unless of course you want to pay $200.00 for a Radar (not worth it).
There is a better solution to the radar and much less expensive (about $5.00 for parts).This is a secret kept amoung armorers though.
If you want to know about it I can send a private email.Keep this in mind also.A 2 stage trigger has it's benefits because you always know where the let-off is (also a built in safety).
So bottom line is,you can have less creap and a much better trigger pull.I charge $55.00 to smooth trigger and make it adjustable as well.
Some guys have 2 trigger groups.1 for match shooting and 1 for the range (just a suggestion).Not all good things are expensive.Let me know what you decide.
