I have a surefire blast warden on one of my ar builds and I love that little flame thrower. I'm onto a new build and have a KAC flash hider that will fit a QDC. I asked KAC directly if they sell mock barrel extensions like the surefire "suppressor trainer". They replied "we do not have them for sale to the commercial market". Then I stumbled upon the below! Does anyone think this baby will survive the real deal being machined aluminum or make an entertaining YouTube fail?
