Also with .050" protrusion you are probably loosing more than .025" of travel leaving you with about .185" travel from sear release to primer ignition maybe less. IMHO the gains are getting going to be keeping the bolt clean from oil and grease. Possibly reducing the protrusion .015" and if someone is offering a better spring.......

Has anyone found a fit for something like this to go between the springs, Desh?
