The TechT MRT Bolt (MASS REDUCTION TECHNOLOGY) for the Empire Invert Mini and Empire AXE 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. The spiral cut pattern allows lengthening of the channels of material to be removed, resulting in lower weight and a really cool look!

Like all of TechT's bolts, the Mini & AXE MRT bolts have been through rigorous R&D and field testing. This testing guided the Mini & AXE bolt to what is now the MRT. Initial prototypes saw the removal of the "cup seal" on the front of the stock bolt. After testing various other o-rings and seals, it was decided that the MRT needed this cup seal on the front of the bolt for the best performance. The removal of this cup 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 cup seal. This important recognition sets the MRT Mini and AXE bolts apart from their competition; no other aftermarket Mini or AXE bolt maintains this important seal. The lightweight and clever design make it the most efficient and fastest bolt available for the Mini and AXE.

The MRT bolt produces less kick, lower pressure, peak efficiency, and great consistency. The MRT's deep cuts allow for greater weight reduction over the stock bolt. The MRT GOLD is 30% lighter than stock. The MRT Gold is hard anodized and teflon coated for minimal drag and friction.
