my SA rifle started life as a mil-spec DPMS m4. over the years i swapped some things out such as the handguard, barrel, trigger, stock, grip.
i have a rock river arms 2 stage trigger, a wilson combat super sniper 20" barrel in 223 wylde that i had my local gunsmith install and he added one of those rubber accu-wedges.
that gun shoots 1/2 in groups at 200 yards from the bench when i do my part with federal factory 53 grain v-max.
