*Due to the force exerted on the BCG with a blow back system, there is a high likely hood of breaking the bolt catch when activated by the LRBHO feature.  New Frontier Armory is not responsible for sending replacements as this is not a warranty issue. 

***WARNING – This firearm is not meant to be fired with the stock in the folded position.  New Frontier Armory is not responsible for any damage caused by attempting to fire with the stock folded.***
