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.

6 reviews for 10.5 AR15 Pistol Kit 10″ Quadrail Upper Assembled With 80% Lower
Only logged in customers who have purchased this product may leave a review.
Q: Does this kit include a lower receiver?
A: Yes — the DT10-014 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 DT10-014 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 DT10-014’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 DT10-014 uses a 10″ 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: The DT10-014 runs a carbine-length gas system — matched to its 10.5″ barrel for consistent cycling.
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 DT10-014’s 10.5″ 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.
