Q: Does this kit include a lower receiver?
A: No — this kit is upper-only, though the BCG, mil-spec Lower Parts Kit, and buffer tube are included. You’ll need to supply your own AR-15 lower.
Q: What caliber is this kit chambered in?
A: 300 AAC Blackout is the caliber for this kit, run through a 1:7 twist 7.5″ barrel, topped with an A2 Flash Hider, 5/8″-24. Note the BCG is machined specifically for 300 AAC Blackout, not interchangeable across calibers.
Q: Can I run this suppressed?
A: Yes — this kit’s 7.5″ .300 Blackout barrel is a common suppressor-host setup, particularly with subsonic loads. A suppressor and its paperwork are on you; neither ships with this kit.
Q: Is the Burnt Bronze finish just on the handguard, or the whole kit?
A: On this kit, the Burnt Bronze finish covers the handguard and receiver-facing components of the upper; the barrel itself retains its Nitride finish.
Q: What gas system does the 7.5″ barrel use?
A: Pistol-length gas system. On this kit’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: This kit’s 7.5″ barrel is well under the 16″ minimum for a standard rifle barrel. Configuring this kit on a lower with a shouldered stock instead of a pistol brace makes it a Short-Barreled Rifle (SBR) under the NFA, requiring ATF Form 1 registration and an approved tax stamp before assembly.
