The VKTR VK-1PW 5.56 NATO piston rifle in Sniper Grey (brand part no. V31100916622) is a low-profile, piston-driven AR-15 with a 13.7-inch barrel. A HUX WRX Flash Hider XL QD is pinned and welded to the barrel to bring it to 16 inches, so the rifle keeps the compact handling of the short barrel. The patented short-stroke piston system matches the footprint and weight of a standard direct-impingement AR-15 and includes a staged gas bleed for suppressed or unsuppressed shooting. Billet ambidextrous controls, a Radian Raptor charging handle and a Hiperfire single-stage trigger come standard. From VKTR Industries, it is aimed at shooters who want a short, fast-handling AR that still runs reliably.

Key Specifications

• The chambering is 5.56 NATO, a widely available cartridge for range and defensive use.
• The barrel is 13.7 inches in a heavy profile, hammer forged with machined cooling flutes and a gas block alignment pin, which saves weight while staying rigid.
• The muzzle device is a HUX WRX Flash Hider XL QD pinned and welded to reach a 16-inch barrel length, which tames flash and supports a quick-detach attachment.
• The twist rate is 1:7, a fast twist that stabilizes a wide range of 5.56 bullet weights.
• The operating system is a short-stroke piston with a one-piece op rod and removable gas block, which runs cooler than direct impingement.
• The trigger is a 4.5 pound single-stage Hiperfire, which gives a crisp, predictable break.
• The handguard is a 12.5-inch VK-1 low-profile design, giving room for lights and accessories without adding bulk.
• The stock is a Magpul SL, a slim stock that keeps the rifle compact and comfortable on the shoulder.
• The grip is a Magpul K2, which gives a more upright angle for confident control.
• The color is Sniper Grey, a muted finish that avoids the stark look of a plain black rifle.
