The Ruger Precision Rimfire 22 LR 18″ Threaded 15rd is a bolt-action .22 LR rifle built for shooters who demand sub-MOA accuracy from a rimfire platform. It pairs a cold hammer-forged barrel with a fully adjustable chassis and AR-pattern controls, making it a direct training analog for centerfire precision rifles. This model ships with a 15-round BX-15 magazine and a Picatinny rail with 30 MOA elevation for long-range optics.

Key Features
- Cold Hammer-Forged Barrel – The 18-inch threaded barrel is hammer-forged from 400-series stainless steel, delivering consistent accuracy across thousands of rounds. WHY IT MATTERS: You get match-grade performance without the premium barrel cost.
- Quick-Fit Adjustable Stock – The Precision Rimfire stock adjusts for length of pull, comb height, and buttpad angle without tools. WHY IT MATTERS: A proper cheek weld and LOP are critical for repeatable shot placement; this system lets you dial in fit in under 60 seconds.
- 15-Inch Free-Float M-LOK Handguard – The aluminum handguard free-floats the barrel for zero contact and includes M-LOK slots for mounting bipods, lights, or rails. WHY IT MATTERS: Free-float design eliminates barrel pressure points that degrade accuracy, and M-LOK gives you modular attachment options.
- 30 MOA Picatinny Rail – The receiver-mounted rail includes 30 MOA of elevation built in. WHY IT MATTERS: This allows you to zero at 100 yards and still have enough elevation adjustment to reach 300+ yards with a 22 LR.
- AR-Pattern Controls – The rifle uses an AR-style grip, safety selector, and bolt release. WHY IT MATTERS: If you train on an AR-15, you can transition to this rimfire without retraining manual of arms—muscle memory carries over.
Who It’s For
This rifle is for law enforcement and military personnel who need a cost-effective training platform that mirrors the ergonomics and weight of a 5.56 precision rifle. It’s also for serious competitive shooters in NRL22 or PRS Rimfire divisions who want a factory rifle that can hang with custom builds. Small-game hunters who value accuracy over magazine capacity will find it effective for squirrels, rabbits, and groundhogs out to 100 yards.
Pros / Cons
- Pro: Sub-MOA accuracy out of the box with match ammunition—verified by multiple independent testers.
- Pro: Fully adjustable stock and 30 MOA rail eliminate the need for aftermarket upgrades.
- Con: The factory trigger pull is crisp but heavy at 4.5 lbs; shooters accustomed to 2-pound triggers may want to swap to an aftermarket unit.

FAQ
Does this rifle accept standard AR-15 grips?
Yes. The Ruger Precision Rimfire uses an AR-pattern grip interface. You can swap the factory grip with any standard AR-15 grip from manufacturers like Magpul, B5 Systems, or Hogue.
What is the twist rate of the barrel?
The 18-inch barrel has a 1:16 twist rate, optimized for standard 22 LR ammunition (36-40 grain bullets). Heavier subsonic loads (45-60 grain) may not stabilize as well.
Is the barrel threaded?
Yes. The barrel is threaded 1/2×28 TPI and includes a thread protector. You can attach a suppressor or muzzle brake directly.
What magazines are compatible?
The rifle ships with one Ruger BX-15 15-round magazine. It also accepts all BX-series magazines, including the BX-1 (10-round), BX-25 (25-round), and BX-25×2 (50-round tandem).
Does the rifle come with iron sights?
No. The receiver has a Picatinny rail only. You must install optics (scope or red dot) to shoot. The 30 MOA rail is designed for scope use.
