The TechT MRT Bolt (MASS REDUCTION TECHNOLOGY) for the for the Invert Mini, Mini GS, Empire Axe, Axe Pro and Empire SYX has been engineered with efficiency and consistency as the most crucial design elements. TechT's MRT system minimizes excess weight by removing portions of the bolt which are not utilized. TechT's spiral cut pattern allows us to lengthen the channels of material to be removed, resulting in lower weights and a really cool look!
Like all of TechT's bolt upgrades, the MRT BOLT bolts have been through rigorous R&D and field testing. Initial prototypes saw the removal of the "rubber tip seal" on the front of the stock bolt. After testing various other o-rings and seals, TechT decided that the MRT needed this cup seal on the front of the bolt for the best performance. The removal of this tip seal, like on other competitors' bolts, actually yielded worse efficiency and a loss of up to 15 fps compared to a bolt with the proper tip seal. This important recognition sets the MRT bolts apart from their competition; no other aftermarket bolt maintains this important seal. The lightweight and clever design make it the most efficient and fastest bolt available for the for the Invert Mini, Mini GS, Empire Axe, Axe Pro and Empire SYX. The MRT bolts produce less kick, lower pressure, peak efficiency, and great consistency. MRT Delrin is about 60% lighter than stock.
