PTR PTR-91 GI .308 Win 18in Parkerized 20rd

The PTR PTR-91 GI .308 Win 18in Parkerized 20rd is a semi-automatic roller-delayed blowback rifle built for practical shooters who demand reliability and accuracy out of the box.

Key Features

• Roller-Delayed Blowback Action – Why it matters: This proven system absorbs heavy .308 recoil into a smooth, predictable cycle, keeping your sights on target for faster follow-ups in three-gun or tactical matches.
• 18-Inch Tapered Barrel – Why it matters: Shorter than the original full-length profile, this barrel shaves weight and improves maneuverability without sacrificing the velocity needed for 600-yard steel.
• Parkerized Finish – Why it matters: The phosphate coating resists corrosion and glare, so you can run this rifle hard in rain, mud, or sun without worrying about rust or reflections giving away your position.
• Accepts HK Claw-Mount Optics – Why it matters: With the factory top rail removed, you can mount a low-profile claw-mount scope or red dot directly to the receiver, maintaining a cheek weld that feels natural.
• 20-Round Detachable Magazine – Why it matters: Standard capacity for competition stages and range sessions – pairs with affordable surplus G3 mags for extended shooting.

Who It’s For

This rifle is built for the competition shooter who wants a battle-proven .308 platform without the price tag of a premium custom build. It’s also a solid choice for the precision enthusiast who appreciates the roller-delayed system’s inherent accuracy and reliability. If you’re shooting three-gun, tactical rifle matches, or just want a hard-use .308 that runs on surplus mags, the PTR-91 GI fits the bill.

Pros & Cons

• Pro: Rock-solid roller-delayed action – cycles everything from 147-grain M80 ball to 175-grain match ammo without hiccups.
• Pro: Low cost of ownership – uses cheap surplus G3 magazines and standard .308 parts.
• Pro: Accepts aftermarket trigger packs (e.g., Bill Springfield) for a cleaner break.
• Con: The factory trigger is heavy and gritty – plan on a trigger job or drop-in pack if you want sub-4-pound pulls.
• Con: Reconditioned condition means cosmetic wear on furniture and metal; not a safe queen.

FAQ

Does the PTR-91 GI accept HK claw mounts?

Yes. The factory top rail is removable, exposing the integral claw-mount slots. You can attach any standard HK claw-mount optic rail or scope mount directly to the receiver.

What condition is the rifle in?

These are reconditioned units. Per PTR Industries, they may show minor wear on the synthetic furniture and working surfaces, but all mechanical components are serviceable and function as new.

Can I use surplus G3 magazines?

Absolutely. The PTR-91 GI is compatible with all standard HK G3/91 pattern magazines, including inexpensive steel surplus options. The included magazine is a 20-round polymer unit.

Is the barrel chrome-lined?

No. The 18-inch barrel is button-rifled and has a Parkerized finish. It is not chrome-lined, but the phosphate coating provides adequate corrosion resistance for normal use.
