Thank you for supporting our Legal Defense Fund!

*This product is part of the 80% Arms Legal Defense Fund. 100% of the proceeds from this product will go toward our legal team to support our lawyers combatting an onslaught of litigation against us and the 2nd Amendment. 

To see where these funds are directly going, look no further than the VanDerStok v. Garland case that the Firearms Policy Coalition (FPC) is undertaking on behalf of us. (We have had multiple wins in this case including receiving a preliminary injunction that protects us from the ATF's nonsensical 2021R-05F rule. The case was even vacated by the 5th Circuit of Appeals and is now awaiting review by the Supreme Court to conclude the case.

*Please Note:
We understand that any sort of heat-treating or coating has the risk of permanently altering your GST-9 MOD1 frame. Contact our support team if you run into issues caused by the Rit-dyeing process. We will be more than happy to help you with any issues or questions during the rit dying process.
