Wraithworks WARP-15 AR-15 Polymer Stripped Lower Receiver

The Wraithworks WARP-15 Stripped Lower is an AR-15 receiver molded from glass filled nylon with the buttstock, buffer tube and pistol grip built in. One piece means less weight and fewer parts to buy. The stock has an A1 length 13" length of pull, M-LOK slots at the rear for a sling, and holes at the front for QD socket inserts. The flared magwell helps with fast reloads, and the whole receiver is lighter than a comparable aluminum lower with a separate stock.

It uses a carbine buffer and spring. The takedown and pivot pins have their detents built in, which removes the spring and detent holes from the lower. The selector spring and detent load from the top. It takes all mil spec fire control groups and cassette style match triggers like the KE Arms DMR and SLT, and it fits most common AR-15 uppers and lower parts kits. Finish it with a lower parts kit, a carbine buffer and spring, and an upper.
