Detailed Description


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 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. 

Our extensive experience as a premier custom builder of AR-15 rifles will ensure your satisfaction with this next generation precision tactical shooting platform.

  • Mil-Spec type 3 hardcoat anodize black finish
  • Hand prepped for a flawless surface finish
  • 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 Mil-Spec forged lower receivers or Wilson BILLet-AR lower receivers and any standard AR barrel
  • Enhanced receiver will not accept some aftermarket bolt releases
  • Approximate Weight, 9.2 Oz.

WC billet upper , black armor tuff.
This upper receiver is a classic, solid and machining is top notch, as always. This is the 4th WC billet receiver I own, there is a reason I come back for more. Tighter BCG raceway, top notch machining, can pin recess has a nice machined transition inside upper, vs the sharp edge that gets rounded off in your typical forged upper. To top it off, WC customer service has always exceeded my expectations. Keep up the great work WC team!
Billet Upper/Lower
Very nice receivers. I built a custom 300 BLK with a stainless fluted barrel. Looks outstanding. I used frog lube on the receivers and the finish just rejected the lube like oil on a Teflon frying pan. The attachment pin for the bolt release is threaded, not a push pin, which surprised me. Takes a 1/16 Allen wrench. The pin hole for the dust cover is different too, no c clip. The hole for the rear take down pin spring hole is hidden under the grip too. Just a few notes to help the next guy.
Great Upper
I own two of these & the dominating feature for me is the tight BCG raceway. Theres hardly any noticeable play between the BCG & the receiver. I have two other billet uppers of comparable cost & you can feel the difference in the amount of play. Im positive this tight fit enhances accuracy of my rifles. I highly recommend the Wilson Billet upper receiver.
