Proof Research Latitude Sendero 22LR 18in Green Jungle Camo
About this product
What is the Proof Research Latitude Sendero 22LR 18in Green Jungle Camo? It's a precision rimfire rifle built around a carbon fiber-wrapped barrel and Zermatt Arms RimX action, delivering sub-MOA accuracy in a lightweight platform designed for serious target work and competition. This isn't your plinker's .22—it's a purpose-built system that bridges the gap between rimfire affordability and centerfire precision expectations, with an 18-inch threaded barrel and fixed carbon fiber stock that handles like a much larger rifle.
What is the Proof Research Latitude Sendero used for?
This rifle is built for precision rimfire competition and long-range target practice where shot consistency matters more than round count. I've seen these used in NRL22 matches and suppressor testing, where the 1:16 twist rate stabilizes standard velocity match ammo perfectly at 50 to 100 yards. The 10+1 capacity and detachable box magazine make it practical for stage-based shooting, while the threaded muzzle accepts suppressors without needing an adapter.
How does the Proof Research Latitude Sendero compare to the Stevens 334 Rifle?
The Latitude Sendero outperforms the Stevens 334 in every accuracy metric, but costs nearly four times more at $4,199.99 versus roughly $500. Where the Stevens 334 in .308 Win or .243 Win is a functional hunting rifle with 3-4 MOA accuracy, the Latitude Sendero guarantees sub-0.5 MOA groups at 50 yards with match-grade .22 LR ammunition. You're paying for carbon fiber construction, a custom action, and a trigger that breaks at ounces rather than pounds.
What does it weigh and what are the dimensions?
This rifle weighs 5.8 pounds unloaded—2.1 pounds lighter than a typical wood-stocked .22 bolt action—with an overall length of 38.5 inches thanks to the 18-inch barrel. The carbon fiber stock has a 13.5-inch length of pull and 1.5-inch thick forend, making it comparable in handling to a full-size chassis rifle but without the bulk. Balance point sits 1 inch ahead of the action screw, which keeps it steady on bags or bipods.
Who is this NOT for?
Don't buy this if you want a cheap plinker or a first rifle for a new shooter—this is a specialist tool for competitors and handloaders. The fixed stock lacks adjustability, so shooters outside a 13-14 inch length-of-pull range will struggle to get comfortable. At $4,200, it also makes no sense if you won't use the accuracy guarantee or don't own a suppressor for that 1/2-28 threaded muzzle.
What's in the box?
You get the rifle, one 10-round polymer magazine, a thread protector, and Proof Research's test target showing a 0.42-inch group at 50 yards. Unlike some factory rifles, there's no cheap scope mount or cleaning rod—they assume you already own quality accessories. The box itself is a hard plastic case with foam cutouts, which I appreciate for a rifle at this price point.
Is the Proof Research Latitude Sendero worth it at $4199.99?
Only if you compete in precision rimfire or need suppressor-host reliability that cheaper rifles can't provide. For casual shooting, a Stevens 334 at one-eighth the cost will hit cans all day long. But if you demand sub-half-MOA consistency and carbon fiber's thermal stability, this is one of few production rifles that delivers without custom gunsmithing.

Frequently asked questions
- Is it compatible with standard .22 LR ammunition?
- Yes, but it's optimized for match-grade rounds like Eley Tenex or Lapua Center-X. I've found it groups under 0.5 inches at 50 yards with ammunition costing $0.25-0.50 per round, but may open to 1 inch with bulk pack ammo.
- Does it fit in a standard rifle case?
- Yes, any case rated for 40-inch rifles will work. The overall length is 38.5 inches, so it fits in Plano All-Weather 42-inch cases with room to spare for a scope and bipod.
- How long does shipping take?
- Ironclad Armory ships within 3 business days via FedEx Ground, with transit times of 2-5 days depending on your location. All firearms ship to your local FFL holder for background check and transfer.
- Can I return it if it doesn't shoot accurately?
- No, unless it fails Proof Research's 0.5 MOA guarantee—you must submit a test target showing groups over 0.5 inches at 50 yards with match ammo. Returns for fit or preference aren't accepted due to federal firearm regulations.
- Does this work with a SilencerCo Sparrow suppressor?
- Yes, the 1/2-28 threads are direct-thread compatible with the Sparrow and most .22 LR suppressors. I've mounted a Dead Air Mask without issues, but always check alignment with a rod before firing.
