The PTR-91 MSG follows the G3 pattern and uses a roller-delayed blowback action with a fluted chamber for reliable extraction. It is built on a stamped steel receiver with a matte black finish and accepts widely available HK G3/PTR-91 pattern magazines. Controls include the paddle-style magazine release, a folding charging handle, and a two-position manual safety.
The 18 inch heavy-profile barrel is fluted and threaded, and it is fitted with a birdcage flash hider. This configuration provides a durable, heat-managing profile while maintaining standard threading at the muzzle for compatible devices.
Sighting is handled by a hooded front post and a diopter rear drum, offering a precise and familiar sight picture for this platform. A welded, receiver-length Picatinny rail is integral to the receiver, providing a solid base for mounting optics.
Furniture includes a slim/standard G3 polymer handguard without an underside bipod groove and a polymer stock with an adjustable cheekpiece and adjustable length of pull, plus a rubber buttpad. The rifle has a front sling loop and a rear stock sling point. A PTR-licensed ventilated handguard with a bottom accessory rail is included and can be installed if desired.
