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 MRTv2 bolt are TechT's newest bolts that will produce less kick, peak efficiency, and great consistency. The MRTv2 offers deeper cuts for greater weight reduction. The MRTv2 GOLD is 30% lighter than stock.
