Silencers get HOT!, boys and girls! Really HOT, really quick!
So when using a suppressor on a centerfire rifle, what can you do to avoid burning yourself during weapon transitions or even basic weapons handling.
One basic solution is the TAB Gear (firstname.lastname@example.org) SAS series of mirage shields, These are distributed through Rifles Only's Pro Shop. http://www.riflesonly.com/
They're intended for keeping the heat mirage from obscuring the view on a sniper's suppressed rifle.
They're also one of the best products out there for keeping assault rifle shooters from burning themselves with their own suppressed semi-auto rifles. While they won't hold up to too much continuous fire, during the average number and rate of rounds expended on an engagement or sensible class, it'll shield the end user from burns jim dandy.
