I KEEP SEEINGTHIS TERM USED ALOT WHAT DOES THIS REALY MEAN. I HAD A LOCAL GUNSMITH PROMISE ME THAT HE COULD GET MY GUN SHOTTING 25% BETTER BY DOING THIS. PLEASE IF ANYONE HAS INFO ON THIS LET ME KNOW.

By accurizing a rifle, various small improvements may be made to a rifle to improve performance. Such include free-floating the barrel, bedding,andlightening the trigger pull. Some guns get great group improvements from this, some have no effect at all, and in rare cases, negative effects.

In my 26+ years,I have never experienced a negative impact on rifle's accuracy directly related to work I have performed on said rifle. Basically,I can sum it up to doing the handwork and blueprinting that the factory cannot afford to do unlizing mass production systems involving tolerences.
I will let others,more skilled in words explain this.
