Description Reviews (0) LMT 40mm m203 receiver. Made to be mounted to any conventional 1913 Picatinny rails. Isn't going to consist of barrel or sight. Contains 3 recoil lugs and three locking lugs to hold to rail. Crafted from 7075 T6 aluminum forging for durability. Timelessness conjures up true greatness. https://denisv443pzi4.empirewiki.com/user
