BILLet Option for Wilson Combat ARs

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