AR15 Tropical Camo M-LOK Builder’s Set

Tropical Camo Cerakote by Weapon Works

Our fall 2022 custom builder’s sets feature expertly machined, high-quality parts with a custom Cerakote Tropical Camo finish!  Each builder’s set includes a Ballistic Advantage Enhanced AR15 Receiver Set and a 9.3″, 12″, or 15″ M-LOK handguard with an ATLAS attachment system.  These sets were all manufactured to have a seamless fit.

The Aero Taper Lock Attachment System (ATLAS) is highly functional, extremely secure, and the best-looking handguard attachment to date!

BA Enhanced Lower Receiver Features

  • Threaded Bolt Catch Roll Pin – Allows for simple bolt catch installation and virtually eliminates the chance of damage to the finish during installation (pin included). 1/16″ Hex Key required for assembly.
  • Integrated Trigger Guard – Eliminates the possibility of breaking the trigger guard tabs by integrating the trigger guard into the lower, creating a stronger, more rigid platform to build upon.
  • Upper Tension Screw – Allows users to fine-tune the fit of the upper and lower receiver using a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
  • Threaded Takedown Pin Detent Recess – This allows users to easily install the Takedown Pin detent and spring using a 4-40 set screw (no more launching detents across the room).
  • Increased Magwell Flare – Increased the flare of the magwell to aid in quick and efficient magazine changes.
  • Marked and milled to accept short-throw safety selectors but will also work with standard selectors.

  • Prices do not include your dealer’s transfer fees.
  • Not eligible for return after transferred into your possession via ATF Form 4473.
  • There will be a 30% restocking fee on all controlled items returned because of failed background checks.

Federal law requires that you be 21 years of age or older to purchase a pistol, stripped receiver, or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver, not a handgun or long gun. However, they are still “firearms” by definition and are subject to the same GCA limitations as any other firearm. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
