Attachment 46910
M&M import 553 pistol registered as SBR. Aimpoint T1 in Spuhr mount. US made one piece Rotex style flash hider. SPG Tech m4 stock adapter, BCM single point receiver endplate sling mount, BCM stock, Magpul MOE-K2 adapted to the SIG lower, SwissArms railed fore-end. I need to add a low profile QD sling mount to the back left 9 o'clock rail. This thing is a bad ass little SBR.
