• Enhanced Carrier and Enhanced Bolt
• Semi-auto carrier - Medium Mass
• Dual extractor springs 
• Delays unlocking of bolt
• Unique contact rail system to reduce drag
• Includes LMT's proprietary coating for durability against heat and wear
• Manufactured to handle increased pressure including suppressed fire

LMT's .223/5.56 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 modified cam path allows for a greater dwell time, and superior extraction. The dual extractor springs help provide a more reliable extraction. Extraction is also greatly improved based on the fact that more of the extractor claw engages the rim of the case. The metal used to create the bolt is also extremely tough and a great improvement over carpenter 158 steel.

Note: for use with semi-automatic rifles
