Features
The high-pressure Enhanced Bolt is a revolutionary advancement for users of .308 Cal/7.62 Cal AR-type rifles, addressing the common issues of excessive primer flow and ejector smear that arise from using factory rounds not optimized for semi-automatic platforms. Traditional ammunition development often overlooks the unique pressure requirements of AR platforms, leading to performance inconsistencies. Our Enhanced Bolt is engineered to mitigate these challenges, offering a significant improvement in reliability and accuracy. Crafted to the same rigorous standards as our standard bolt offerings, the Enhanced Bolt is designed to handle over-pressured loads effectively, reducing primer flow, ejector smear, extraction issues and ignition reliability problems. This innovative design broadens the range of compatible ammunition and load densities for AR .308 Cal/7.62 Cal rifles and other calibers like 6.5mm and 6mm variants. The bolt assembly is precision machined from SAE 9310 steel, renowned for its exceptional strength and durability. This ultra-strong steel alloy, also used in Formula 1 transmission gears, ensures the bolt lasts up to 10 times longer than standard carbon steel alternatives, withstanding up to 60,000 rounds. Its tough, ductile inner core resists stress fracturing, while the hard outer surface prevents galling and wear, making it ideal for high-impact, high-heat applications such as sustained full-auto fire. Meticulous machining of radiuses on all 90 degree corners of the locking lugs ensures even distribution of impact forces, reducing the risk of premature wear and cracking. The fully supported extractor face and precise extractor engagement guarantee smooth, reliable cycling, making the high-pressure Enhanced Bolt an essential upgrade for any serious AR-platform enthusiast seeking enhanced performance and longevity.
- Constructed from SAE 9310 steel for enhanced durability and prolonged service life
- DLC coating offers exceptional surface hardness and lubricity while preserving a ductile core
- Surface finish with minimal friction
- Fully compliant with military specification sub-components
- The enlarged diameter of the cam pin hole significantly reduces the occurrence of common bolt failures
- Enhanced lug geometry to minimize wear and facilitate smoother locking and unlocking
- The enhanced ejector minimizes head case extrusions and decreases brass smearing
- The enhanced extractor optimizes the extraction function and eliminates common ejection failures
- The enhanced gas ring minimizes internal friction and carrier wear while sustaining an almost indefinite gas seal
