Our enhanced bolts have a more resilient coating and stronger heat treat, as well as the cartridge case being fully supported by the bolt face.

When you shoulder your weapon, it must operate flawlessly - even in harsh weather conditions. Our superior carriers are enhanced with a more resilient coating, refined heat treat, and a fully supported cartridge case by the bolt face.

The extractor on the bolt assembly has "lobster tail" appearance and offers a double-spring system. The improved bolt is made from a stronger material than the GI-issue bolt. LMT® bolts and carriers provide dependable performance - BECAUSE FAILURE IS NOT AN OPTION®.

  • 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.
