AR15 80% lower that accepts the Sig p250/p320 9mm/40 magazine.
With the military adopting the P320 platform in some branches, and the exploding popularity of the P320 Handgun, we decided to build a lower that would accept these magazines. The rest of the parts used are common AR9 parts. This allows the end user to have an AR based pistol or carbine that accepts the same magazine as their p320/p250 carry gun.
This lower features our patented LRBHO feature that locks the bolt back on the last round.
