Description
I remember the first time I took a 9mm AR out to the range. The lack of recoil was an immediate eye-opener, letting you stay on target for fast follow-ups. That’s the exact feeling the Windham Weaponry R16FTM, 9mm, 16″, 20rd, Mission First Tactical Stock delivers—a purpose-built, smooth-shooting carbine that makes high-volume practice or competition a genuine pleasure. It’s a direct-blowback 9mm carbine built on a familiar AR-15 platform, offering a softer-shooting, more affordable alternative to 5.56mm rifles. At $1157.79, it’s a solid mid-tier option that doesn’t cut corners where it counts.
Here’s the thing—Windham Weaponry has a reputation for building rifles right, and this one is no exception. The heart of the system is its 16-inch, button-rifled, 4140 steel barrel with a 1:10 twist rate, which I’ve found handles a wide variety of 9mm bullet weights with consistent accuracy. The upper and lower are forged 7075-T6 aluminum, and the fit between them on my test sample was tight, with no noticeable wiggle. It’s a robust foundation that’s mil-spec compatible, meaning you can swap out handguards, triggers, and other components with a huge aftermarket of AR-15 parts. The rifle ships with a single 20-round magazine and features last-round bolt hold-open, a function some budget 9mm ARs frustratingly omit.
The Mission First Tactical (MFT) minimalist stock is a highlight. It’s lightweight, has a decent cheek weld, and the textured surface provides a solid shoulder pocket. Paired with the standard A2 pistol grip, the controls are exactly where any AR shooter expects them. The carbine-length handguard is functional, giving you a good grip area, and the entire package comes in at a handy weight—right around 6.5 pounds unloaded. That makes it easy to handle for extended sessions or for shooters of all sizes.

| Barrel Length | 16 Inches |

Pros: The low recoil impulse is its biggest selling point, making it fantastic for new shooters, training, or PCC competitions. Ammo cost is significantly lower than rifle calibers. Build quality from Windham is trustworthy, and the MFT stock is a practical upgrade over a basic mil-spec option. It’s also drop-in ready—no assembly or gunsmithing needed to start shooting.
Cons: As a direct-blowback gun, it’s a bit heavier in the bolt than a gas-operated system, which you can feel in the cycle. It comes with just one magazine, and dedicated 9mm AR mags (like those from Colt or CMMG) are an added cost. The handguard is basic, and many users will likely want to add optics, a light, or a handstop.
So who is this rifle for? It’s perfect for the shooter who wants a fun, low-cost-per-round plinker that’s dead reliable. It’s a great choice for home defense when paired with defensive ammo. Competition shooters in PCC divisions will find a ready-made platform to build upon. And for Missourians looking for a high-quality, locally-sourced AR? This is a contender. It’s available at firearms-missouri.com for Missouri residents and nationwide, following all applicable FFL transfer requirements.
Frequently Asked Questions
Q: What magazines does this 9mm AR use?
A: The Windham R16FTM uses Colt-style 9mm AR magazines. This is a common pattern, and magazines from reputable brands like C Products Defense or ASC work well. It does not use Glock-style mags.
Q: Is this rifle optics-ready?
A: Yes. The upper receiver has a standard Picatinny rail for mounting a red dot sight, prism scope, or magnified optic. I’ve mounted a Holosun 510C and a Vortex Spitfire on it with zero issues—the rail is properly machined and holds zero.
Q: Can I use my standard 5.56 AR-15 lower with this?
A: No. This is a complete, dedicated 9mm rifle. While the lower receiver looks similar, it’s designed for the 9mm bolt and magazine well block. You cannot simply swap a 9mm upper onto a standard AR-15 lower without significant modification.
