Key Features
- Roller-Lock Delayed Blowback Action – Why it matters: This proven system handles high-pressure .308 rounds with less recoil than direct gas guns, keeping your follow-up shots fast and on target.
- M-LOK Aluminum Handguard – Why it matters: Lightweight and rigid, it lets you attach lights, lasers, or grips exactly where you need them without adding bulk or shifting zero.
- Welded Picatinny Top Rail – Why it matters: It’s a one-piece steel rail that won’t lose zero under heat or impact, giving you a rock-solid mount for red dots or LPVOs.
- Adjustable Iron Sights – Why it matters: You get a backup sighting system that’s zeroed from the factory—no need to buy extra irons for close-range work.
- 20-Round Magazine Included – Why it matters: You’re ready to shoot as soon as you open the box, with enough capacity for range drills or home defense.
Who It’s For
This pistol is for the shooter who wants a compact .308 platform for truck-gun duty, suppressed use, or as a lightweight hunting sidearm for thick brush. It’s also ideal for students in tactical pistol courses who want a single platform that bridges the gap between a handgun and a rifle—same manual of arms, bigger punch.
Pros and Cons
- Pros: Rock-solid roller-lock reliability; M-LOK handguard for modular accessories; Picatinny rail holds zero; adjustable irights included; compact enough for vehicle carry.
- Cons: It’s heavy at 7.2 lbs unloaded—lighter than a full rifle but heavier than most AR pistols. The roller-lock system also requires high-quality .308/7.62 NATO ammo to cycle reliably (per PTR Industries).

FAQ
Does the PTR-91 PDWR accept standard AR-15 pistol grips?
Yes. The polymer grip is designed to accept standard AR-15-style pistol grips (same tang and screw pattern). You can swap in your preferred grip for better ergonomics.
What optics will fit the top rail?
The welded Picatinny rail is full-length (13 slots) and accepts any optic with a standard Picatinny mount—red dots, holographic sights, or compact LPVOs. It also works with magnifiers.
Can I use this pistol with a suppressor?
Yes, but you’ll need to add a muzzle device with 5/8×24 threads (the barrel is threaded, but the included flash hider is not suppressor-optimized). PTR recommends using a quality .30-caliber suppressor rated for .308 pressure.
Is the M-LOK handguard free-floating?
Yes. The aluminum handguard is free-floating, meaning it attaches only to the barrel nut and does not contact the barrel—this maintains accuracy and prevents point-of-impact shift from accessories.
