Whether you exclusively run your AR-15 suppressed or simply want a more reliable BCG, the SureFire Optimized Bolt Carrier Group is what you need. It comes with a buffer weight and spring designed to be used with this AR-15 bolt carrier group to further improve functionality. The BCG itself comes with a ton of improvements including a lengthened cam pin slot and a neutrally balanced weight to delay unlocking of the bolt and allow for more gas to escape the barrel. This lowers chamber pressure to decrease wear on parts and reduces gas from expelling out the ejection port. Additionally, the balanced counterweight helps to keep the carrier at the rear of the gun longer for more reliable feeding of ammunition and nearly eliminates bolt bounce during lockup. The SureFire OBC reduces cyclic rate and felt recoil and the proprietary coating reduces friction for a smooth operating rifle.

Features:

• Improved cam path to delay unlocking
• Neutrally balance counterweight reduces cyclic rate
• Reciprocating weight reduces bolt bounce
• Long stroke design improves feeding reliability
• Anti-friction coating resists corrosion and makes cleaning easy
• Includes optimized buffer and buffer spring
• Great for SBRs and suppressed use

The SureFire AR-15 Optimized Bolt Carrier also features a shortened gas key and a shorter buffer to increase stroke by 60% to allow for more time for the magazine to feed rounds into the chamber. The combination of the buffer weight carrier weight, and spring rate increase inertia when the bolt picks up a round out of the magazine.

SureFire designs and manufactures a wide variety of firearms accessories, from weapon lights to suppressors but they built their name on weapon laser sighting systems. Since then, SureFire has been recognized as a leading manufacturer of rugged, powerful lights. The SureFire name has become synonymous with excellence in handheld illumination. They believe in providing a product that will give you the edge when dealing with unknown threats in the dark and any of the other possible reasons why a bright, small light could be used.
