PTR PDWR BR Features The PTR PDWR BR uses a roller-delayed blowback system paired with a heat-treated full-auto capable bolt carrier the same mechanical foundation that has made PTR s rifles known for reliability. Chambered in .308 Win the 8.5 heavy contour barrel is threaded 5/8x24 and cut with a 1:10 twist to stabilize common .308 bullet weights. The black nitride finish on the barrel resists corrosion and wear from repeated firing in field conditions. A 20-round capacity gives the shooter substantial firepower in a platform short enough to maneuver in tight spaces or vehicles. The heavy contour profile also adds mass forward of the receiver which helps tame muzzle movement during rapid strings of fire from a roller-delayed action known for its heavy reciprocating mass. The mil-spec anodized aluminum receiver carries a Picatinny rail and an M-LOK compatible handguard inviting lights optics and other accessories to be mounted wherever the shooter needs them. An SB Tactical brace and black polymer grip round out the ergonomics giving stable shoulder or brace-assisted support without the length of a traditional rifle. The black Parkerized receiver finish adds further protection against the elements matching the barrel s corrosion resistance. At 8.1 lbs and including a magazine gun lock and case the PDWR BR is a complete ready-to-run package for shooters who want rifle-caliber performance in a pistol footprint. The combination of the M-LOK handguard s accessory real estate and the brace s compact profile makes the PDWR BR equally at home as a truck gun a home defense platform or a range pistol for shooters who already run the .308 roller-delayed system and want a shorter companion to their PTR rifle.
