LMT Defense AR-15 5.56 Enhanced Bolt (L7Q3B)

Lewis Machine & Tool (LMT) Enhanced Bolts are designed to improve upon the shortcomings found with the Mil-Spec AR-15 bolts when firing full-auto, suppressed, or from a short barrel weapon system. If you have a full-auto, SBR, or suppressor -- the LMT 5.56 Enhanced Bolt is the best possible upgrade to increase reliability and functionality.

Built from a proprietary material that LMT claims is both stronger and easier to clean -- the Enhanced Bolts have a more resilient coating and stronger heat treat, as well as the cartridge case being fully supported by the bolt face. The extractor on the bolt assembly has "lobster tail" appearance and offers a double-spring system, which provides stronger and more consistent extraction with much greater spring life when compared to a single spring extractor. The modified locking lugs increase durability over a GI Bolt, especially when dealing with high-pressure, and overgassed rounds (ex. M855A1).

Features:

• Modified cam path increases dwell time, allowing for a much easier extraction
• Five gas vent holes
• Extractor claw engages more of the cartridge case rim to ensure positive extraction
• Geometry of locking lugs decreases stress
• Manufactured from a much stronger material than GI issue bolt
