The TECHT MRT (MASS REDUCTION TECHNOLOGY) Pro Series TPX Bolt has been engineered with efficiency and consistency as the most crucial design elements. We have also added a soft touch face to our TPX Bolt, (the same used on our Phenom MRT Pro Series Bolt) which will significantly decrease ball breakage. Our MRT system minimizes excess weight by removing portions of the bolt which are not utilized. Our spiral cut pattern allow us to lengthen the channels of material to be removed, these results produce a very dynamic looking bolt. Players that upgrade to the MRT Pro Series TPX Bolt will see significant increases in efficiency and the elimination of ball breakage typically associated with the stock TPX bolt. The TECHT MRT Pro Series Bolt is made of a combination of aircraft grade aluminum and delrin, which results in a super light design. As with all of our products it carries a Full Lifetime Warranty.
The TechT MRT Pro Series TPX Bolt utilizes the stock spring. It is not necessary to install our TPX Low Pressure Spring Kit when using our MRT Pro Series Bolt. In our testing we found that changing to a different spring (lighter spring) caused issues with the bolt hitting the breech with too much force. We saw increases of 20-30 FPS when changing out the stock bolt for the MRT Pro Series Bolt. Our tremendous increase in efficiency is due to the combination of the soft-touch face- which helps seal the off the barrel when fired, the tremendous change in weight, and our high flow face. This means more mags per cartridge! The sound signature is also greatly reduced when adding the MRT Pro Series Bolt.
