The DT10-012 is a complete 10.5″ chrome moly, Nitride finish 5.56 NATO pistol build kit finished in Black, bundled with an 80% stripped lower receiver — everything needed to build a pistol from the ground up.

  • Caliber – 5.56 NATO (.223/5.56)
  • Barrel – 10.5″ Chrome Moly, Nitride finish
  • Twist Rate – 1:7
  • Gas System – Carbine-length
  • Muzzle Device – A2 Flash Hider, 1/2″-28
  • Handguard – 7″ Quad Rail (Picatinny)
  • Upper Receiver – M4 flat-top
  • Finish – Black
  • Lower Receiver – 80% stripped lower receiver included

What’s Included: a complete M4 flat-top upper — chrome moly barrel, mil-spec 5.56-specific BCG and charging handle, 7″ quad rail (picatinny) handguard, gas block and tube — plus a mil-spec Lower Parts Kit, a US-made pistol buffer tube with buffer and spring, and an 80% stripped lower receiver. It does not include a magazine, jig/tooling, or sights.

This complete Pistol Kit is not an FFL item because the lower is not complete — it is machined 80% and still needs machining to finish. Pair it with our 80% lower jig kit, or browse our full lineup of AR-15 .223/556 Pistol Build Kits.

WE DO NOT SHIP 80% LOWER RECEIVERS TO THE FOLLOWING STATES – NY, RI, NJ, CT, MD, DE, HI, IL, NV, CA, WA, DISTRICT OF COLUMBIA, DENVER, CO OR BOULDER, CO

Q: Does this kit include a lower receiver?
A: Yes — the DT10-012 includes an 80% stripped lower receiver, which still requires machining (jig and tooling sold separately) before it’s a complete, legal lower.

Q: What caliber is this kit chambered in?
A: Chambering on the DT10-012 is 5.56 NATO (.223/5.56) — a 1:7 twist, 10.5″ barrel, topped with an A2 Flash Hider, 1/2″-28. The BCG is caliber-specific to 5.56 NATO, so it won’t swap with a different caliber’s bolt carrier.

Q: Does the twist rate matter for the ammo I run?
A: Yes — the DT10-012’s 1:7 twist stabilizes heavier 5.56/.223 bullet weights (62–77gr) particularly well, in addition to standard 55gr loads.

Q: What handguard is installed, and does it free-float the barrel?
A: The DT10-012 uses a 7″ Quad Rail (Picatinny) handguard, free-floated off the barrel for consistent accuracy and zero retention under sustained fire.

Q: What gas system does the 10.5″ barrel use?
A: A carbine-length gas system, sized specifically for the DT10-012’s 10.5″ barrel to keep the action cycling reliably.

Q: Can this be built as a rifle instead of a pistol?
A: At 10.5″, the DT10-012’s barrel falls well short of the 16″ rifle-length minimum. Building it with a shouldered stock rather than a brace reclassifies it as an SBR under the NFA — that requires ATF Form 1 approval and a tax stamp before you assemble it that way.
