About This Firearm
The Ruger Precision Rimfire is a deliberate copy of the centerfire Ruger Precision Rifle in .22 LR — same AR-pattern pistol grip, same adjustable folding stock, same free-float handguard, same AICS-pattern magazine interface. It ships with a 30 MOA Picatinny scope base and one 15-round BX-15 magazine. It costs a fraction of what the centerfire RPR runs, which is exactly the point.
The Ruger Marksman Adjustable trigger breaks at 3.6 lbs from the factory, heavier than the CZ 457's 2.5-3.1 lb factory range but adjustable down within the housing. The 18" barrel is shorter than the CZ 457's 20.5" or the Tikka T1x's 20", which matters less for .22 LR ballistics than it would in a centerfire, but the trade-off is a 38.63" overall length that still fits in most rifle cases. The 1/2"-28 threaded muzzle accepts any standard rimfire suppressor without an adapter.
What the RPR does better than anything else in this class is let a centerfire precision shooter run the same manual of arms — same grip, same stock adjustments, same prone position, same scope — at .22 LR ammo cost. NRL22 and Rimfire Sporter competitors use this rifle specifically because the transition back to a centerfire chassis rifle requires zero relearning.

Strengths & Limitations
- Ships with a 30 MOA Picatinny base installed — you can mount virtually any centerfire scope or red dot straight from the box, and the same scope and rings from your centerfire RPR will fit without modification.
- The 15-round AICS-pattern magazine is the largest capacity of the three precision .22 bolts in this class. The Tikka T1x runs 10 rounds and the CZ 457 ships with a 5-round mag.
- At 108.8 oz (6.8 lbs) unloaded, this is the heaviest of the three. The Tikka T1x comes in at 91 oz — nearly a pound lighter — which matters when carrying in field positions for extended stages.
- The 3.6 lb trigger is the heaviest in the precision .22 class — the CZ 457's factory range is 2.5-3.1 lb and the Tikka T1x sits around 3.5 lb. The RPR's trigger is adjustable, but getting it significantly lighter typically requires some tuning time.

Frequently Asked Questions
What optics and accessories fit the Ruger Precision Rimfire?
The RPR ships with a 30 MOA Picatinny rail installed, so it accepts any standard Picatinny-mount scope, red dot, or LPVO without modification. The same scope rings you use on a centerfire Ruger Precision Rifle will work here. The free-float handguard has M-LOK slots on the bottom and sides for bipods, lights, and foregrips — Atlas and Caldwell bipods with Picatinny or M-LOK mounts attach directly. Suppressor-ready owners can thread any 1/2"-28 rimfire can onto the barrel without an adapter.
Does the Ruger Precision Rimfire accept AICS magazines?
It uses an AICS-pattern magwell, but it ships with Ruger's own BX-15 magazine rather than true AICS steel mags. The BX-15 is reliable and well-regarded. Some aftermarket AICS-style 10/22 magazines will fit, but the compatibility isn't universal — check the manufacturer's fitment list before buying extras. The stock 15-round BX-15 is the safest bet for feeding reliability.
Is the Ruger Precision Rimfire good for NRL22 competition?
It's one of the most common rifles in NRL22 and Rimfire Sporter matches. The adjustable length-of-pull (15.5" as spec'd, adjustable shorter), AR-grip, and prone-ready chassis geometry translate directly from centerfire PRS shooting. The main limitation competitors note is the 3.6 lb trigger — many owners invest in a trigger upgrade relatively early. The rifle is legal across NRL22 divisions as shipped.
