Detailed Features 

The 20" carbon fiber tension barrel is precision lapped and button rifled with a match chamber, the construction that backs up the accuracy claims. 
 
The precision machined aluminum receiver uses dual extractors and opposing locking lugs, which keeps extraction reliable across a range of ammunition. 
 
The adjustable cheek riser (1" of travel) and adjustable length of pull (12.5"-14.5") cover a wide range of shooter builds. The 7075 aluminum billet chassis includes a folding stock with a locking hinge and MagneLock technology, so the rifle folds down for transport without looseness when deployed. 
 

Usage Scenarios 

1. Small Game Hunting: The .17 HMR caliber is well-matched for rabbits, squirrels, and similar game, enough velocity for clean kills at distance with minimal meat damage. 
2. Target Shooting and Competition: The match chamber and precision barrel make it a practical choice at the range and in competitive rimfire formats. 
3. Skills Practice: The adjustable stock lets shooters work on fundamentals without fighting a poor fit.

Owners of the Christensen Arms MPR Rimfire .17 HMR generally have a lot of good things to say, particularly about the build. The carbon fiber construction comes up constantly. Shooters like that it keeps weight down without making the rifle feel flimsy. Accuracy at both short and longer distances gets positive marks, which matters for the varmint hunting crowd who are the natural audience for this caliber.

The trigger draws frequent praise for being crisp and responsive. Aesthetics also come up; the rifle has a modern look that appeals to people who want something that feels purpose-built rather than traditional.

On the critical side, price is the most common friction point. Some owners think the quality justifies the cost; others feel alternatives exist at lower price points. Availability and supply have also been issues for buyers trying to track down this specific model.

A few users wish for more factory customization options out of the box. They appreciate that the rifle accepts scopes and bipods, but want more variety in how it ships.
