TechT MRT Bolt Upgrade for the Invert Mini, MINI GS, Empire AXE, Empire AXE PRO and Empire SYX

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. Our MRT system minimizes excess weight by removing portions of the bolt which are not utilized. Our 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 our 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, we 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.

We decided to made two different bolts because we realize that some people would like to keep an all metal bolt, while others prefer self lubricating qualities of delrin. Both tested very similar, so you really can't go wrong. The metal bolt weighs about 3 grams more than the delrin, however both show excellent improvements over the stock bolt. The MRT Gold is hard anodized and teflon coated for minimal drag and friction.

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 the MRT Delrin is about 60% lighter than stock.

We have not had any issues out of either bolt. We just like to give players the option to have either a metal or delrin bolt.
