SureFire Optimized AR-15 Bolt Carrier Group - 5.56 NATO

The SureFire Optimized AR-15 Bolt Carrier Group is a next-generation solution designed specifically for 5.56 mm/.223 caliber rifles and carbines. Engineered with innovative features, this bolt carrier group delivers enhanced reliability and performance, whether firing suppressed or unsuppressed. One of its standout features is the long-stroke design, which provides 60% more travel beyond the magazine. This increased travel time improves magazine feed, reducing the likelihood of bolt-over-base malfunctions. Additionally, the dual-spring dwell weight significantly delays the direction-change of the bolt carrier, ensuring reliable operation.

The SureFire Optimized Bolt Carrier also features an improved cam path that delays the unlocking of the bolt, resulting in a 15% decrease in chamber pressure before unlocking. This design enhancement contributes to smoother operation and improved overall performance. To enhance durability and performance, the bolt carrier group is coated with self-lubricating Diamond-Like Carbon (DLC) and S-Line coatings. These advanced coatings reduce friction, providing consistent and dependable operation even in adverse conditions.
