Questions & Answers
Can I use this upper receiver for my .450 Bushmaster build! Expert Answer

No. The Wilson Combat AR-15 Billet Stripped Upper Receiver in .458 SOCOM takes only two caliber specific parts-a .458 specific bolt and barrel. It is designed to be used with only .458 SOCOM with an ejection port modified specifically for .458.

Does this work with a standard AR10 lower or does it need to be matched up with a Wilson Combat lower? Manufacturer Answer

This can work with with standard Mil-Spec forged lower receivers or Wilson BILLet-AR lower receivers and any standard AR barrel.

Burly beast AR upper by Pete, June 24, 2021
This upper is BURLY! Designed to eliminate any weak points with extra metal added in the main body, this upper will obviously last for years. Rock solid construction will help with durability and accuracy. One note: it does not fit in a normal block...

Was really bummed out when this upper did not work with my handgaurd due to needing a mil spec upper reciever. If that's not an issue for you its a solid choice for a clean billet upper. May have to get one in the future for a different build.

WC BILLet upper by Koal, Verified Owner, July 27, 2020
Great product, tighter BCG raceway. Love the slick side. Can’t go wrong with this well made upper receiver. Especially useful when paired with a heavy barrel, added thickness produces less fess flex and more support for the barrel

amazing quality !!! by Spencer, Verified Owner, February 24, 2026
I love these billet receivers, I’m currently working on my third setup. I’m having a great experience so far with no issues and just under 500 rounds.

No Forward Assist by Kyle, Verified Owner, July 30, 2021
True spec pic rail on top. The 'tighter raceway' has not proved beneficial nor a hindrance. After a few hundred rounds my BCG did minimally cut into the inner side (cam pin), probably from a sub par no name BCG. Charging handle also removed the anodi...

Product Info for Wilson Combat AR-15 Billet Stripped Upper Receiver

Bill Wilson and the designers at Wilson Combat have put all of their talent and techniques into designing an upper receiver that is a high-precision 100% machined unit for the AR platform of rifles. Machined from 7075-T6 aircraft-grade billet aluminum allows them to both address structural design weaknesses in standard rifles and provide some of the highest tolerances in the industry when it comes to AR15 Upper Receivers. Since 1977, Wilson Combat has been known as highly innovative and an industry leader when it comes to high-performance 1911's and tactical rifles, and a Wilson Combat upper is no exception to their quality standards.image

A billet upper receiver means that it has been machined start to finish from a single piece of aircraft aluminum, rather than forged. This allows for more strength in the parts, allowing for higher tolerances and durability. Rather than offering the standard forged receiver, the Wilson Combat stripped upper has extra material around stress points and more precise fitting when combined with the AR lower receiver.
