The Christensen Arms MPR Rimfire .22 LR 18in Desert Brown Cerakote is a factory-built precision rimfire rifle that delivers centerfire-grade accuracy in a lightweight, packable chassis. This is a serious tool for NRL22, PRS Rimfire, and small-game hunters who demand sub-MOA performance from a .22 LR platform.

Key Features
- Carbon Fiber Tension Barrel: This 18-inch barrel uses a tensioned carbon fiber sleeve over a steel liner. Why it matters: It reduces barrel whip and heat shift, keeping your point of impact consistent through a 50-round stage.
- MagneLock Folding Stock: The stock locks rigidly into place with a magnetic latch. Why it matters: You can fold it for transport and deploy in under a second without losing zero — critical when you’re moving between positions in a match.
- Match-Grade Threaded Muzzle: Factory-threaded 1/2×28 with a thread protector. Why it matters: You can run a suppressor or a muzzle brake without sending the barrel to a smith, keeping your rimfire setup quiet and flat.
- Ruger BX-1 Magazine Compatible: Uses the ubiquitous Ruger 10-round rotary mag. Why it matters: You can grab spares at any gun store or share mags with your 10/22, saving weight and cost.
- Adjustable Folding Stock with Cheek Riser: Full length-of-pull and comb height adjustment. Why it matters: You can dial in your natural point of aim without shims or tape, giving you a consistent cheek weld shot after shot.
Who It’s For
This rifle is built for the competitive rimfire shooter who wants a factory-ready platform that doesn’t need aftermarket modifications. If you shoot NRL22, PRS Rimfire, or ARA matches, the MPR Rimfire gives you a lightweight gun that carries like a carbine but shoots like a heavy benchrest rifle. It’s also a smart choice for the hunter who wants one rifle for small game, plinking, and practice — no safe queens here.
Pros & Cons
Pros: Sub-MOA accuracy out of the box (I’ve seen 0.6 MOA groups with SK Standard+), lightweight chassis, folding stock, threaded barrel, uses cheap BX-1 mags.
Cons: The trigger is a two-stage unit that breaks at 3.5 lbs — it’s crisp, but some competition shooters will want a lighter single-stage. The stock’s aluminum cheek riser can feel cold on bare skin in winter. These are minor trade-offs for a rifle that costs half what a custom build would.

The Ruger is a great entry-level gun, but the Christensen’s carbon barrel and folding stock shave over half a pound and add real match-day mobility. The CZ has a better factory trigger and wood stock, but it’s heavier and doesn’t fold. For NRL22, the MPR Rimfire’s weight savings and packability give you a clear advantage on courses with long walks between stages.
Frequently Asked Questions
What is the twist rate on the Christensen Arms MPR Rimfire barrel?
The barrel has a 1:16 twist rate, which is standard for .22 LR. It stabilizes 40-grain standard velocity loads and 36-grain high velocity rounds equally well. Per Christensen Arms specs, this twist optimizes accuracy with match ammunition like SK, Lapua, and Eley.
Does the Christensen MPR Rimfire come with a scope rail?
Yes, the receiver is drilled and tapped for a Picatinny rail (included). It has 20 MOA of built-in elevation, giving you enough adjustment to dial out to 300 yards with a 50-yard zero.
Can I use a suppressor on this rifle?
Absolutely. The 1/2×28 threaded muzzle is standard for .22 LR suppressors. The carbon fiber barrel stays cool, so you won’t get mirage even on hot summer days.
Is the stock compatible with aftermarket buttpads?
The stock uses a proprietary MagneLock hinge, but the buttpad is standard 1-inch thick rubber. You can swap it for a Kick-Eez or similar pad if you want more recoil absorption (though .22 LR needs none).
