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, A2 flash hider, 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.

Only logged in customers who have purchased this product may leave a review.
Q: Does this kit include a lower receiver?
A: Yes — the DT10-024 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: 5.56 NATO (.223/5.56) is the caliber for the DT10-024, run through a 1:7 twist 7.5″ barrel, topped with an A2 Flash Hider, 1/2″-28. Note the BCG is machined specifically for 5.56 NATO, not interchangeable across calibers.
Q: Does the twist rate matter for the ammo I run?
A: Yes, and it’s worth knowing for the DT10-024: a 1:7 twist favors heavier 5.56/.223 bullets (62–77gr) without giving up performance on standard 55gr ammo.
Q: What handguard is installed, and does it free-float the barrel?
A: The DT10-024 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 7.5″ barrel use?
A: A pistol-length gas system, sized specifically for the DT10-024’s 7.5″ barrel to keep the action cycling reliably.
Q: Can this be built as a rifle instead of a pistol?
A: At 7.5″, the DT10-024’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.

Love this kit I’ve bought a couple and it’s always arrived sooner than expected
Eric Paro (verified owner) –
We bought this kit and for the price we were really not expecting it to be as good of quality as it is. It is definitely well worth the money and absolutely no regrets on buying it. I will say milling Out a lower receiver is much harder than I thought it would be. We ended up buying a Spikes stripped lower receiver and all of the parts in the kit fit it perfectly. The upper matched perfectly with the Spikes lower. If I was going to order the kit again I would order it without the lower receiver and just buy a stripped lower receiver to complete the build. It shipped out pretty fast considering everything that is going on. So I guess I highly recommend Daytona tactical. Thanks for a great kit!
