Does this kit include an 80% lower receiver?
No. The DT10-080 does not include a stripped lower receiver — it ships with a mil-spec Lower Parts Kit and pistol buffer tube already included, so you’ll just need to add your own AR-15 lower receiver to complete the build.

What caliber is this kit chambered in?
.300 AAC Blackout — it uses a caliber-specific BCG and is not interchangeable with a 5.56 bolt carrier group.

Can I run this suppressed?
.300 Blackout is a popular suppressor host caliber, especially with subsonic ammunition, but you’ll need your own NFA-compliant suppressor and paperwork — this kit does not include one.

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

What gas system does the 7.5″ barrel use?
A pistol-length gas system, matched to the barrel length for reliable cycling on .300 Blackout.

Can this be built as a rifle instead of a pistol?
Only with a lower and stock combination that complies with current ATF rules; changing a pistol build’s configuration can trigger NFA/SBR requirements, so check current regulations before altering it.
