Student of the Gun
I purchased this BCG because Allen at Sprinco recommended it over every other option on the market. I have NOT been disappointed at all! following the SOTAR protocol I mic'd and gauged everything and this unit passed with flying colors. The AR10 is no where as forgiving as the AR15 when it comes to component fitment and gassing issues and this BCG is a HUGE leap above the rest in gas efficiency and durability. I would HIGHLY RECOMMEND this unit to ANYONE with a AR10 who wants to fix a gas issue OR who just wants to dramatically increase the longevity and durability of their rifle.
