Wilson Combat has been building custom 1911 pistols since 1977. By 2002, they were machining AR related products such as receivers and handguards.
Since then, Wilson Combat has expanded its product line to become a formidable manufacturer of custom firearms and parts. These include its high-end, AR-style rifles offered in a wide range of calibers.
In this article, we’ll take a look at their standard weight, non-ambidextrous, AR-15 billet upper and lower receiver set (TR-LOWUPP-BIL-ANO) in a custom pistol build.
Wilson Combat Matched Billet Receiver Set Features
- CNC machined from 7075-T6 aluminum billet stock
- Stylized shell deflector
- M4-style extended feed ramps offering better reliability with various calibers
- Undersize bolt raceway providing smoother chambering, improved feeding and improved recoil dynamics.
- Slick side upper receiver
- Oversized magwell for faster reloads
- Precision threaded receiver and reamed pin holes
- Hex screw bolt catch retention
- Anodize finish
Weight of Stripped Upper and Lower Receivers
- Upper Receiver: 9.2 oz
- Lower Receiver: 9.4 oz
At 18.6 oz, the Wilson Combat stripped billet receiver set is a little on the heavy side, especially compared to the 12.3 oz, 2A Armament Balios Lite stripped receiver set.
Wilson Combat Matched Billet Receiver Set Pricing
MSRP: $615. Street price is about $400.
Update August 2022
It seems that Wilson Combat no longer offers their billet upper and lower receivers as a “matched set” directly from their website, although you may still be able to purchase their billet sets from some online retailers. However, it looks like you can still buy the Wilson Combat upper and lower receivers “individually” directly from Wilson Combat’s website. Here is a link to their AR-15 billet upper receiver. Here is a link to their AR-15 billet lower receiver.
Wilson Combat Matched Billet Receiver Set Fit and Finish
The design and machining of the Wilson Combat billet upper and lower receivers are among the finest I have seen. I really like the design of the oversized magwell. I also love the wider integrated trigger guard which has nicely beveled edges that sit comfortably against the finger.
Wilson Combat also makes a lighter weight (7.6 oz) version of their upper billet receiver, which has material removed from the sides and a Picatinny top rail with a scalloped design that is the same found on the Picatinny top rail of their handguards.
That said, the upper and lower receivers do have a little bit of side-to-side slop, despite using the included black rubber tube/bumper that is supposed to provide vertical tension between the upper and lower for a tighter fit. This rubber tube/bumper sits inside a machined hole within the lower receiver. Some people may find the side-to-side slop of this matched billet receiver set to be disappointing. Keep in mind that inserting a loaded mag almost eliminates this side-to-side slop.
Wilson Combat’s standard anodized finish is a flat grey color (see image below), that tends to easily show scratches and marring. You can always order your receiver set directly from Wilson Combat and pay extra for their “Armor-Tuff” finish in a color of your choice.
Armor-Tuff is Wilson Combat’s proprietary finish that is similar to Cerakote and costs $90 to have it applied to their receiver set. According to the Wilson Combat website, Armor-Tuff must be ordered in conjunction with an Anodized Upper/Lower Set.
Color options for Amor-Tuff are:
Flat Dark Earth
The anodized finish of their 9.3” handguard also did not match the anodized finish of the receiver set. Therefore, I ended up having the receiver set and handguard Cerakoted in Sniper Grey, which can be seen in all of the images of the fully assembled AR-15 build in this article.
What I Don’t Like about the Wilson Combat Billet Receiver Set
As noted earlier, the Wilson Combat billet receiver set has some side-to-side slop, which is annoying. I’m also not a fan of their anodized coating as it is a dull grey finish that easily shows scratches and marring, in addition to not matching the anodized Wilson Combat handguards. This is why you may also want to have it Cerakoted, which of course, adds to the cost of the receiver set and handguard.
Another thing I don’t like is that Wilson Combat puts the rear takedown detent channel/hole for the detent spring, further down the rear of the lower receiver so that the rear detent spring must be held in place by the top of the pistol grip. This is a real pain in the ass, so much so, that I almost ended up using a 4-40 tap to put in a threaded allen screw that would capture the rear detent spring.
And finally, I don’t like that the Wilson Combat Billet upper is not compatible with the Strike Industries polymer Ultimate Dust Cover.

At the Range
For this particular build, I chose to use the Bootleg adjustable bolt carrier group instead of an adjustable gas block, to more easily adjust the gas for use with and without a suppressor. However, because the Bootleg adjustable BCG does not reduce the flow of gas as much as an adjustable gas block, I needed to use a heavier buffer (H3) for suppressed shooting.
Having shot approximately 300 rounds of 5.56 NATO 55 gr FMJ suppressed (YHM Turbo T2), the Wilson Combat custom build performed flawlessly.
