What’s Included: a complete barreled upper — chrome moly Nitride barrel, mil-spec BCG and charging handle, Ghost M-Lok free-float handguard, gas block and tube — plus an 80% (unmachined) AR-15 lower receiver. It also includes a mil-spec Lower Parts Kit and a US-made pistol buffer tube with buffer and spring. A jig is not included — you’ll need one to finish machining the 80% lower.
Pick up an 80% lower jig kit to finish machining the included receiver, or browse our full lineup of AR-15 pistol build kits.
This 5.56 complete Pistol Kit is not an FFL Item because the Lower is not complete — it is machined 80% and still needs machining to complete.
