Description
Picture this: you’re glassing a ridgeline, the morning sun filtering through the timber. You need a rifle that’s steady, precise, and blends into the Missouri hardwoods. You need a tool that bridges the gap between a benchrest queen and a hard-use field rifle. That’s the mission profile for the Windham Weaponry VEX-SS, .223/5.56, 20″, TrueTimber MC2, SS, 5 rd.
The Windham Weaponry VEX-SS is a complete, factory-built AR-15 upper receiver assembly chambered in .223 Wylde for superior accuracy with both .223 Remington and 5.56 NATO ammunition. It features a 20-inch stainless steel barrel with a 1:8 twist, a TrueTimber MC2 camouflage finish, and ships with a 5-round magazine. This precision-oriented upper is designed for drop-in compatibility with any mil-spec AR-15 lower receiver, making it a versatile upgrade or build core. Available at firearms-missouri.com for Missouri residents and nationwide.
Let’s break down what makes this upper a serious contender. The heart of the system is that 20-inch stainless steel barrel. The extra length provides a full powder burn for maximum velocity and a flatter trajectory, giving you a tangible edge at distance. The 1:8 twist rate is the modern sweet spot—it stabilizes the heavy 77-grain match bullets favored by precision shooters while still handling lighter varmint loads with authority. Paired with the .223 Wylde chamber, you get match-grade accuracy potential without sacrificing the ability to run bulk 5.56 ammo. This isn’t a picky rifle; it’s a practical one.
The TrueTimber MC2 finish isn’t just for looks—though it does provide excellent breakup in multi-terrain environments. It’s a durable, baked-on coating that protects the stainless steel from the elements, whether you’re in a humid river bottom or a dusty CRP field. The rifle weighs in at approximately 7.8 lbs when paired with a standard lower, offering a solid, steady platform. The included 5-round magazine keeps the profile sleek for prone shooting or hunting in states with capacity restrictions. At $1073.56, this upper represents a focused investment in precision.
Here’s the thing—this is a build that requires no gunsmithing required. You simply mate it with a quality mil-spec lower, like an Aero Precision M4E1 or a stripped Anderson lower, insert two takedown pins, and you’re operational. The system includes a bolt carrier group and charging handle, so it’s truly a complete upper receiver assembly. The handguard provides ample real estate for a bipod mount up front and a forward grip or barricade stop further back, allowing you to set it up exactly for your intended use, be it NRA High Power competition or predator control.

Pros: The .223 Wylde chamber and stainless barrel are a proven accuracy combination. The 20-inch length maximizes ballistic performance. TrueTimber MC2 is a functional, durable finish. Complete with BCG and CH for immediate use. Drop-in compatibility offers huge build flexibility.
Cons: The 20-inch barrel makes for a less maneuverable rifle in tight quarters. The 5-round magazine is limiting for some training scenarios. As an upper alone, it requires a separate lower receiver purchase and FFL transfer.
This upper is for the shooter who values precision over portability. It’s for the hunter who wants a dedicated, camouflaged coyote or varmint rig. It’s for the competitor dipping a toe into service rifle matches, needing a reliable and accurate foundation. It’s also for the builder who wants a turn-key precision upper from a reputable manufacturer like Windham—known for their legacy and quality control—without assembling every component themselves.
Frequently Asked Questions
Q: Is this a complete rifle?
A: No, this is a complete upper receiver assembly. It includes the barrel, handguard, bolt carrier group, charging handle, and forward assist. It must be attached to a separate mil-spec AR-15 lower receiver, which requires an FFL transfer for firearm purchases.
Q: Why a .223 Wylde chamber instead of just 5.56?
A: The .223 Wylde chamber is a hybrid design. It allows for safe firing of both .223 Remington and 5.56 NATO ammunition while providing the tighter tolerances of a .223 chamber, which typically yields better accuracy with match-grade .223 rounds. You get versatility and precision.
Q: Can I attach a muzzle device to this barrel?
A: Yes. The barrel features standard 1/2″-28 threads, making it compatible with a vast array of muzzle brakes, compensators, and flash hiders. Just ensure any device is properly aligned and torqued.
