Over the last few months we have tested many different crazy looking super light bolt designs and had mixed results. After long months of testing on the field and shooting over our high precision chrono, we found that using the stock type bolt face oring as well having no cuts between the two rear orings yielded the best consistency and efficiency. My results found that removing the stock-type face o-ring and replacing it with a standard o-ring reduced our velocity at any pressure and dwell by about 15-30 fps and decreased consistency. We think its because the stock type o-ring seals in the barrel really well. We also found that placing a groove between the two rear orings for added weight reduction actually decreased consistency. Instead of a standard deviation of between 3-4 FPS with no groove, we got a standard deviation of about 15 fps with the groove. Weird, huh? We hated that our more cut down versions didn't test better....but what can ya do. Invert did a really good job when designing the bolt for this gun. The MRTv1 bolts we're offering produced less kick, peak efficiency, and great consistency. The MRTv1 GOLD is 28% lighter than stock, and the MRTv1 Delrin is about 50% lighter than stock. Currently the best bolts we have made are the ones you are seeing.
