Does this kit include a lower receiver?
No. Despite wording elsewhere on the page, this kit ships without a lower receiver, magazine, sights, or jig/tooling — it is not an FFL item.

What makes this different from our flat handguard kits?
It uses a classic A2 sight tower gas block combined with a round A2-style 2-piece polymer handguard, instead of a Picatinny or Keymod rail.

What twist rate is the barrel?
1×7 twist, chambered in 5.56 NATO with M4 feed ramps.

Is the bolt carrier group and charging handle included?
Yes, a mil-spec M16 BCG and charging handle are both installed.

Can I upgrade components before I order?
Yes, upgrade options for the BCG, charging handle, lower parts kit, flash hider, and stock are available at checkout.

Is this kit made in the USA?
Yes, the kit is assembled in the USA.
