Key Features
- Carbon Fiber Tension Barrel: The 20-inch carbon fiber tension rimfire barrel reduces weight and dissipates heat faster than steel barrels, so you can shoot longer strings without losing accuracy.
- Folding Stock with Adjustable Cheek Piece: The FFT carbon fiber cheek piece adjusts for height and length of pull, and the stock folds to the right for compact storage or transport — ideal for getting in and out of a truck or pack.
- Billet Aluminum Chassis: The rigid aluminum chassis provides a stable bedding surface for the action and free-floats the barrel, which helps maintain consistent point of impact as the barrel heats up.
- Threaded Muzzle: The muzzle is threaded (1/2x28) for direct attachment of suppressors or muzzle brakes, so you can quiet the report or add a compensator without a gunsmith.
- Adjustable Trigger: The trigger is user-adjustable from 2.5 to 5 lbs, letting you dial in the pull weight for precision shooting or field use without swapping parts.
Who It’s For
This rifle is built for the rimfire shooter who wants a lightweight, accurate platform that can go from the range to the field without weighing you down. It’s a good fit for small-game hunters who hike into their spots, target shooters who want to practice fundamentals with cheap ammo, and anyone who needs a compact precision rifle that fits in a backpack or case. The adjustable stock and trigger also make it a solid choice for youth shooters or smaller-framed adults.
Pros and Cons
- Pros: Lightweight at 5.5 lbs; carbon fiber barrel reduces heat buildup; folding stock for easy transport; threaded muzzle for suppressor use; adjustable trigger from 2.5 to 5 lbs.
- Cons: The carbon fiber barrel can be sensitive to barrel cleaning techniques — avoid aggressive solvents or brushes that might damage the carbon fiber wrap. Stick to a bore guide and patch-only cleaning for best results.

FAQ
What type of magazines does the MPR Rimfire use?
It uses standard 9-round rotary magazines that are compatible with most 10/22-style aftermarket mags. We stock OEM and extended options.
Can I mount a scope on this rifle?
Yes. The receiver is drilled and tapped for Picatinny rail mounts. We recommend a low-profile 30mm scope ring setup for a clean cheek weld.
Is the carbon fiber barrel accurate?
Per Christensen Arms specs, the carbon fiber tension barrel is designed to hold sub-MOA accuracy with match-grade .22 LR ammo. The tension construction reduces barrel whip and harmonics.
Does the stock lock when folded?
Yes. The folding mechanism has a positive latch that locks the stock in both the open and folded positions. It does not interfere with the trigger or action.
What is the twist rate of the barrel?
The 20-inch barrel has a 1:16 twist rate, which stabilizes standard and high-velocity .22 LR rounds well for targets and small game.
According to NSSF data, rimfire rifles now account for over 40% of all new rifle sales in the U.S., making a precision rimfire platform like the MPR a smart choice for shooters who want to practice fundamentals without breaking the bank on ammo.
