MasterPiece Arms 308PMRRHBLKPBA PMR 308 Win 10+1 24″ Stainless Steel Polished Black Aluminum Black V-Bedded BA Hybrid Chassis Stock Right Hand

The MasterPiece Arms 308PMRRHBLKPBA PMR .308 Win 10+1 24″ Stainless Steel Polished Black Aluminum Black V-Bedded BA Hybrid Chassis Stock Right Hand is a factory-built precision rifle that skips the build-it-yourself hassle and delivers sub-MOA performance out of the box. This is a turnkey long-range system with a hand-lapped 416 stainless steel barrel, a TriggerTech trigger, and a fully adjustable hybrid chassis—no smithing required.

Key Features

• Hand-lapped 416 SS barrel: This isn’t a button-rifled blank pulled from a bin. MPA hand-laps each 24″ stainless barrel to minimize friction and copper fouling, which translates directly to consistent sub-0.5 MOA groups with match ammo.
• TriggerTech trigger: A fully adjustable, zero-creep, single-stage trigger with a frictionless release. You get a crisp 1.5–4 lb pull that eliminates the “stacking” you feel in budget triggers—critical for clean break at 600+ yards.
• 20 MOA scope rail + inclinometer leveling system: The built-in 20 MOA rail gives you enough elevation travel to dial out to 1,000 yards without maxing your turrets. The inclinometer helps you verify cant angle, so your windage holds stay true.
• Adjustable LOP and cheek riser: The hybrid chassis lets you dial length of pull from 12.5″ to 14.5″ and raise the cheek piece 0.75″ without tools. You can index your eye relief exactly to your scope’s exit pupil.
• V-bedded action interface: The aluminum chassis uses a V-block bedding system that locks the barreled action into a repeatable, stress-free position. No epoxy, no floating screws—just consistent torque and alignment.

Who It’s For

This rifle is for the shooter who wants to skip the barrel nut and torque wrench and go straight to load development. It’s for the PRS competitor who needs a reliable .308 trainer or match gun that doesn’t require a gunsmith’s touch to hold 0.5 MOA. It’s also for the hunter who demands a single-shot capable, 10-round repeating platform in a lightweight chassis.

Pros/Cons

• Pro: Factory-sub-MOA guarantee with match ammunition—verified by multiple independent reviews showing 0.4–0.6 MOA five-shot groups.
• Pro: AICS magazine compatibility means you can run Magpul, Accurate-Mag, or MPA’s own mags without feeding issues.
• Con: The polished black barrel finish shows carbon and copper fouling quickly. You’ll want to wipe it down after every range session to avoid discoloration.
• Con: The included Plano Basic Rifle case is functional but not foam-cut for this specific chassis—you may want to upgrade to a hard case with custom cutouts for transport.

Comparison

The MPA PMR competes directly with custom barreled actions from Geissele but comes at a lower price point with a fully adjustable chassis. For shooters who already own a Remington 700, the Timney trigger is a budget upgrade—but you won’t get the barrel or chassis quality.

FAQ

Last updated: April 2026

According to MPA specs, over 60% of their PMR rifles tested at the factory shoot sub-0.5 MOA with match ammunition. This is a production rifle that competes with semi-custom builds at half the cost.
