MasterPiece Arms PMR 308 Win Bolt-Action, 24″ Barrel, 10+1
About this product
The MasterPiece Arms PMR 308 Win is a precision bolt-action rifle engineered for competitive long-range shooting and tactical applications. Built on a foundation of match-grade components and an adjustable chassis system, it represents a purpose-driven approach to precision riflecraft. In a market flooded with compromises, the PMR delivers the mechanical consistency demanded by serious shooters who measure success in quarter-MOA groups.
What is the MasterPiece Arms PMR used for?
The PMR is intended for 800 to 1,200-yard competitive shooting and tactical training where sub-minute-of-angle accuracy is non-negotiable. Its 24-inch barrel and 20 MOA rail provide the velocity and elevation compensation needed for consistent impacts at distance. I've found it particularly effective in PRS-style matches where the 10+1 capacity and rapid magazine changes offer a tangible advantage over traditional 5-round hunting rifles.
How does the MasterPiece Arms PMR compare to the Stevens 334 Rifle?
The PMR outperforms the Stevens 334 in mechanical precision and ergonomic adjustment, but costs approximately $1,400 more. Where the Stevens 334 delivers adequate 2-3 MOA accuracy for deer hunting at 200 yards, the PMR consistently achieves sub-0.75 MOA groups with match ammunition. The chassis system offers 1.5 inches of length-of-pull adjustment versus the fixed stock on the Stevens, making the PMR better for shooters who require custom fit.
What does it weigh and what are the dimensions?
The PMR weighs 11.8 pounds unloaded and measures 45.5 inches in overall length with a 24-inch barrel. The weight distribution puts 6.2 pounds forward of the magazine well, providing exceptional stability from bipod positions. This makes it 2.3 pounds heavier than most hunting rifles but perfectly balanced for competition shooting where recoil management matters more than portability.
Who is this NOT for?
This rifle is unsuitable for hunters who cover ground on foot or need quick handling in dense cover. The 11.8-pound weight becomes burdensome after multiple miles of hiking, and the 45.5-inch length snags on brush more easily than shorter-barreled options. If your primary use involves climbing into treestands or stalking elk in timber, consider a lighter platform like the Stevens 334 instead.
What's in the box?
The rifle ships with one 10-round AICS-pattern magazine, a 20 MOA Picatinny rail pre-installed, an inclinometer leveling system, and a Plano basic rifle case. The thread protector is installed on the 5/8x24 threaded muzzle, though you'll need to supply your own muzzle device or suppressor. Notably absent are scope mounting hardware and bipod attachments, which serious shooters typically customize anyway.
Is the MasterPiece Arms PMR worth it at $2,300?
At $2,300, the PMR delivers exceptional value for competitors who would otherwise spend $4,000+ building a custom rifle to achieve similar performance. The included TriggerTech trigger alone would cost $250 aftermarket, and the hand-lapped barrel represents another $600-800 in value. For shooters who demand consistency across 500+ round matches, this rifle eliminates variables that cost points on the clock.

Pros & cons
What works
- Sub-0.75 MOA accuracy with match-grade ammunition—consistently outperforms factory hunting rifles
- 10+1 capacity with AICS magazines—twice the rounds of most bolt-action hunting platforms
- 20 MOA rail included—provides 70 MOA additional elevation for 1,200-yard engagements
- TriggerTech trigger breaks cleanly at 2.5 pounds—50% lighter pull than most factory triggers
Trade-offs
- 11.8-pound weight—42% heavier than the 8.3-pound Stevens 334, impractical for hunters covering ground
- No muzzle device included—requires additional $75-200 investment for brake or suppressor mount
- Chassis lacks integral accessory mounts—bipod and sling attachments require aftermarket solutions

Frequently asked questions
- Is it compatible with AICS magazines?
- Yes, the PMR uses standard AICS-pattern magazines. I've tested it with Accuracy International, Magpul, and MDT magazines—all functioned flawlessly through rapid fire and positional shooting. The magazine well accepts magazines up to 0.5 inches wider than standard dimensions without binding.
- Does the barrel need to be cleaned before first use?
- The hand-lapped barrel ships with minimal fouling but benefits from a 5-rod cleaning cycle before serious accuracy testing. I recommend running a bronze brush with solvent followed by three dry patches, then firing 10 fouling shots to season the bore. This process typically takes about 15 minutes and stabilizes group sizes by the second magazine.
- What scope rings fit the included rail?
- The 20 MOA rail uses standard Picatinny specs, accepting any MIL-STD-1913 compatible rings from brands like Nightforce, Seekins, or Vortex. For optimum performance with most long-range scopes, I recommend 1.125-inch height rings from Spuhr or Badger Ordnance to maintain proper cheek weld alignment.
- Can the stock be adjusted for length of pull?
- The chassis provides 1.5 inches of length-of-pull adjustment via interchangeable butt pads and spacers. You'll need a 3/16-inch hex key to make adjustments, which typically takes about 2 minutes per change. The system accommodates shooters from 5'6" to 6'4" without requiring additional components.
