The PTR 91 GI .308 Win 18in Green Fixed Stock 10+1 is a roller-delayed blowback semi-automatic rifle built for shooters who demand reliability and accuracy from a classic battle-proven platform. This example, in reconditioned condition, delivers the same rugged performance as a new build at a fraction of the cost, with a tapered 18-inch barrel and fixed green synthetic stock. Chambered in .308 Win / 7.62 NATO, it’s ready for high-volume range sessions or precision matches.

Key Features
- Roller-Delayed Blowback Action – Why it matters: This proven system soaks up recoil and cycles reliably under rapid fire, keeping your sights on target for faster follow-up shots in competition.
- 18-Inch Tapered Barrel – Why it matters: The classic profile balances maneuverability with velocity retention, giving you consistent 168-grain match bullet performance out to 600 yards.
- Fixed Green Synthetic Stock – Why it matters: Lighter than wood, impervious to weather, and equipped with sling attachment points for stable prone or barricade support.
- Paddle-Style Magazine Release – Why it matters: Ambidextrous and instinctive, it lets you drop a mag without breaking your firing grip—critical for stage transitions.
- 10+1 Capacity – Why it matters: Compliant in most states while still giving you enough rounds for a full COF without reloading.
Who It’s For
This rifle is for the competitive shooter who wants a .308 battle rifle that’s proven in service and on the clock. It’s also ideal for the budget-minded precision enthusiast who isn’t afraid of a little cosmetic wear in exchange for a mechanically sound platform.
Pros & Cons
- Pro: Rock-solid reliability – the roller-delayed system runs dirty and wet without hiccups.
- Pro: Affordable entry into the HK-style ecosystem compared to new builds.
- Con: The fixed stock limits LOP adjustment for shooters with shorter arms; consider an aftermarket buffer tube if you need more adjustability.

FAQ
Is this rifle in new condition?
No, it’s reconditioned. The receiver and barrel are mechanically sound, but the green synthetic stock may show minor cosmetic wear like scuffs or light scratches. Function is 100%.
Does it come with a magazine?
Yes, it includes one 10-round magazine. You can use standard HK91/G3 pattern mags for higher capacity if your state allows.
What type of ammunition does it require?
It cycles both .308 Winchester and 7.62x51mm NATO. For best accuracy in matches, use 168-grain or 175-grain match loads. Avoid steel-cased ammo for the first 200 rounds during break-in.
Can I mount a scope or red dot?
Yes, the receiver has a welded rail for optics. You’ll need a low-profile mount to maintain cheek weld with the fixed stock.
How does the roller-delayed blowback system affect accuracy?
It’s inherently accurate—the barrel is fixed and doesn’t tilt. Expect sub-MOA groups with quality match ammo once you find the right load.
