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 upper receiver set is 100% machined in their 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.

Wilson Combat’s 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 feed ramps 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.
  • Good match with standard GI lowers or Wilson BILLet-AR lower receivers and any standard AR barrel.
  • Hand prepped for a flawless surface finish.
  • Mil-Spec hard anodized black finish.
  • Enhanced receiver will not accept some aftermarket bolt releases.

Beautifully Manufactured Upper Receiver
Superb fit and finish.Beautifully made.Everything assembled perfectly.Of note, there is no Forward Assist on this receiver.It is shipped stripped so you're going to need an ejection port cover (cover, hinge rod, spring and circlip).Best of all, it was in stock!Very nice kit.
