Does this kit include an 80% lower receiver?
No. The DT10-170 ships with a mil-spec Lower Parts Kit and pistol buffer tube already included — you’ll just need to add your own AR-15 lower receiver to complete the build.

Is the FDE finish just on the handguard, or the whole kit?
The Flat Dark Earth Cerakote covers the handguard and receiver-facing components of the upper; the barrel itself retains its Nitride finish.

What caliber is this kit chambered in?
5.56 NATO, also compatible with .223 Remington.

What gas system does the 7.5″ barrel use?
A pistol-length gas system, matched to the barrel length for reliable cycling.

What is the House Keymod rail?
A slim, free-float Keymod handguard designed for lightweight accessory mounting without adding bulk.

Can this be built as a rifle instead of a pistol?
Only with a lower/stock combination that complies with current ATF rules; check current NFA/SBR regulations before reconfiguring.
