The TechT MRTv2 (MASS REDUCTION TECHNOLOGY) Invert Mini Bolts have been engineered with efficiency and consistency as the most crucial design elements. 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 as having no cuts between the two rear orings yielded the best consistency and efficiency.
The MRT bolts produce less kick, lower pressure, peak efficiency, and great consistency. The MRT's deep cuts allow for greater weight reduction in both the GOLD and Delrin versions.
The MRT GOLD is 30% lighter than stock, and theMRT Delrin is about 60% lighter than stock.
