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.

Q: Does this kit include a lower receiver?
A: Yes — the DT10-028 includes an 80% stripped lower receiver that arrives already machined, ready for your lower parts kit to complete the build.
Q: What caliber is this kit chambered in?
A: The DT10-028 is chambered in 5.56 NATO (.223/5.56), with a 1:7 twist 7.5″ barrel, topped with an A2 Flash Hider, 1/2″-28. Because 5.56 NATO uses a caliber-specific BCG, it isn’t interchangeable with a different caliber’s bolt carrier.
Q: Does the twist rate matter for the ammo I run?
A: It does. At a 1:7 twist, the DT10-028 handles the full range of common 5.56/.223 loads, including heavier 62–77gr bullets that slower twists struggle to stabilize.
Q: What handguard is installed, and does it free-float the barrel?
A: The DT10-028 uses a 4″ Quad Rail (Picatinny) handguard, free-floated off the barrel for consistent accuracy and zero retention under sustained fire.
Q: What gas system does the 7.5″ barrel use?
A: Pistol-length gas system. On the DT10-028’s 7.5″ barrel, that length keeps the action running reliably without over- or under-gassing.
Q: Can this be built as a rifle instead of a pistol?
A: Only with a lower and stock combination that complies with current ATF rules. The DT10-028’s 7.5″ barrel is below the 16″ rifle-length minimum, so pairing it with a shouldered stock instead of a brace makes it an SBR under the NFA, requiring registration and a tax stamp first.
