About this product
Built for mil-spec AR-15 uppers, lower parts kits and buffer tubes: the RL556v3 accepts those slides and parts once the receiver is finished, and runs STANAG AR-15 magazines. Listed for builders who want a rifle on the same bench; the RL556v3 is not a pistol frame.
Threadless pistol grip design specific to Polymer80 lowers; the buffer tube housing is reinforced. What ships: RL556v3 80% AR-15 lower receiver with solid core and flared magwell, polymer jig, trigger-hole drill guide, drill bits, end mill.
Sold as an unfinished frame or receiver. Check your state and local law before ordering; we do not ship where unserialized frames are prohibited.
