Bolt Systems | Invert Mini & Empire AXE MRT Bolt Systems


The TechT MRT Bolt (MASS REDUCTION TECHNOLOGY) for the Invert Mini and Invert AXE 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 bolts, the Mini & AXE MRT bolts have been through rigorous R&D and field testing. This testing guided our 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, we 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 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 made two different bolts because we realize that some people would like a metal bolt, while others prefer 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. The MRT Gold is hard anodized and teflon coated for minimal drag and friction.
