A day out training is something we all look forward to, running and gunning, practicing those tactical moves, and sending a bunch of ammo down range into the target. A fun day can quickly go South by accidentally coming in contact with a hot muzzle. If your muzzle device makes contact with you or your clothing, the best case scenario is ruined clothing or gear and worse case a painful blistering burn. Set that hot rifle down in its case and you might melt the nylon or put it in the back of the car ( I have done this) and burn a hole in the the carpet of the wife's SUV.

The Crucible(R) Heat Shield is made of 6061-T6 Aluminum and extends the Hardened Arms AR15 quad rails out in length so that the handguard covers the entire barrel and muzzle brake. This serves to protect and shield the shooter from burns and as an added bonus it looks (no pun intended), amazingly cool. Its extra length and matching
vent ports create a custom streamlined look that absolutely rocks! The Crucible(R) Heat Shield and SMC muzzle brake offers all of the recoil dampening muzzle rise reduction of a great muzzle brake. While the system does not reduce sound or flame signature, its heat shield is very effective and its look will definitely enhance your AR15!

The Crucible(R) Heat Shield is sold as a complete system and is available on our 7" 10" 12" and 15" screw mount Quad rails with versions coming soon for the SDX(TM) Hardened Arms Handguard. The Crucible(R) Heat Shield Rail Extension is a factory mounted accessory for Hardened Arms(R) Handguards only.
