Designed by Bill Wilson and the Wilson Combat design team as the base for the ultimate precision tactical AR-15 rifle, the BILLet-AR matched upper and lower receiver is 100% machined in our Berryville, Arkansas, facility.

The Wilson Combat BILLet-AR receiver was engineered from the ground up to address structural design weaknesses in standard USGI receivers and enhance overall tolerances. The BILLet-AR upper receiver has a precise bolt raceway for smoother chambering, more rigid receiver walls to reduce firing flex, an oversize magazine well for quick reloads, an integrated trigger guard for gloved use, and added lower receiver strength. Our extensive experience as a premier custom builder of AR-15 rifles will ensure your satisfaction with this next generation precision tactical shooting platform.

  • CNC machined from 7075-T6 aerospace aluminum billet stock
  • Picatinny top rail
  • Shell deflector
  • M4-style extended feedramps for excellent reliability with a wide variety of calibers
  • Undersize bolt raceway for smoother chambering, improved feeding and enhanced recoil dynamics
  • Smooth side profile without forward assist for maximum accuracy potential
  • Oversize, EDM-cut magazine well
  • Precision threaded receiver and reamed pin holes
  • Hand prepped for a flawless surface finish
  • Mil-Spec hard anodized prior to final finishing

The BILLet-AR is only available from Wilson Combat as a custom upgrade to existing AR-pattern rifle models and on complete upper assemblies.


Raddlock Magazine Lock Button AR Upgrade for California Residents

To help our customers maintain compliance with California law we are offering the Raddlock Magazine lock as an upgrade to Wilson Combat Custom AR Rifles sold in that state.

The AR Raddlock Magazine Lock Bullet Button provides a unique two-position operation, making it one of the most flexible designs available for use on California legal AR rifles, and is precision machined from 6061 aircraft aluminum with hard coat anodizing.

Position 1 acts in the same way as any of the other bullet button locks, in that the magazine can only be removed with the use of a tool.

Position 2 allows the AR Raddlock to be activated with a press of the finger, just like a standard magazine release button. Position 2 is perfect for shooting outside of California or when using a .22 rimfire upper. Never use position 2 inside California with a centerfire upper and any banned features installed on your rifle, as that would construct a banned assault weapon and is punishable by California law.


This lock kit has NOT been approved by CA DOJ. This magazine lock has been designed to conform to the law as written in CA Penal Code § 12276.1 (a), which defined “detachable magazine” as any ammunition feeding device that can be removed readily from the firearm with neither disassembly of the firearm action nor use of a tool being required. Title 11 CCR § 5469 (a) “A Bullet or Ammunition cartridge is considered a tool.”

Parts installed by Wilson Combat will match finish of rifle unless otherwise specified by customer. A 50% deposit of the estimated work cost on complete rifles, or a $50 deposit on customer-supplied rifles, is required at the time the work is scheduled. The balance is due upon completion. Cancelled work orders are subject to a $50 cancellation fee. Please do not send items not necessary for the custom work such as: gun rugs, gun boxes, bushing wrenches, etc. All firearms are left in shop at your own risk. Once your custom work is completed, a final invoice for the balance will be mailed.

Please do NOT send items such as gun rugs, gun boxes, bushing wrenches, etc. Please include a detailed letter of the problem or services you require by printing out the gunsmithing rates form. Your custom work will not be scheduled until we have received your firearm, $50 deposit and a signed work order form. Due to Federal regulations, customer’s firearms must be returned to address from which they were received. If you have a change of address, written request for such change is required.
