Trooper-Gear has a new version of their SHTF Wrap (Stop Heat TransFer Wrap). The SHTF+ Wrap is very similar to the original in form and function but it benefits from the addition of thermal insulating material that is sewn into the wrap. The thermal insulation allows it to protect the user from an even wider range of temperatures.
The SHTF+ Wrap is secured around your free float rail via Velcro. It protects from heat (and cold), provides grip, and protection for the rail when bracing on barricades. It is fits most slick-sided free float tubes (and many 4 rail tubes) and it adds minimal thickness which is nice when you have purposely chosen your rail to be thin. You can even sandwich your weapon light’s tape switch in the Velcro portion of the wrap.
Many of the slick sided free float tubes do not have a heat mitigation solution available. The SHTF+ Wrap is universal enough that it can fill that role. Check out the SHTF+ Wrap at Trooper-Gear.com.
