[GunCon 2024] VKTR Industries DI Bolt Carrier Group With Precision Cam

Last year at TriggerCon, VKTR Industries introduced their new piston-driven VK1 AR-15 in rifle and pistol configurations. At this year’s GunCon 2024 at Brownells, they introduced their brand new VKTR Industries DI Bolt Carrier Group for Direct-Impingement AR-15 rifles and pistols. This new DI BCG features the same precision cam geometry as the VK-1 piston rifle’s BCG, the goal of which is to have a smoother operation and less contact inside the receiver during lockup and unlock of the bolt.

NEW VKTR INDUSTRIES DI BOLT CARRIER GROUP

VKTR’s new DI BCG will be available as a complete, drop-in component for standard direct-impingement AR-15 pattern rifles and pistols. VKTR Industries describes their precision cam as having been designed to eliminate contact between the cam pin and the inside of the upper receiver by using a long-advance cam path. VKTR Industries’ explanation and features can be seen below.

Precision-machined, complete direct-impingement Bolt Carrier Group with a patented long-advance cam path that correctly times the rifle, finished in thin dense chrome. The patented enhanced cam pin provides consistent lock up reducing headspace variations. Match grade performance right out of the box, and a true drop-in component that will work with any barrel and gas system length.PRECISION CAM PINA Precision Cam pin with tighter tolerances compared with the standard milspec component, providing improved shot to shot consistency in AR platform weapons. The cam pin head features a directional arrow for uniform lapping, and is designed to minimize upper receiver contact when not used in conjunction with the Long Advance Bolt Carrier, while providing full bolt stability and control.CORRECTED TIMINGBy correcting the legacy cam path, the bolt unlocks at 22.5 degrees rather than 20.7 degrees ensuring the cam pin is at top-dead-center where it should be, thus avoiding interference with the receiver wall aft of the the cam pin recess. By delaying unlocking by almost 2 degrees, residual chamber pressure is reduced allowing the cartridge to fully release from the chamber wall easing extraction. The long advance cam path results in a flatter shooting platform with less recoil, even in over-gassed weapons, and smoother locking and unlocking all reducing muzzle rise.
