The BattleComp 1.5 in black oxide is back in stock (seems like they’re constantly selling out). The BC1.5 has the same performance as the BC1.0 and 2.0 SVC and so will probably evoke the same sort of “BattleComp Tourettes” the first time you shoot it. The 1.5 has been extended and pre-drilled for permanent attachment on 14.5” barrels needing a 16.1” overall lengthy. Professional installation is required. This BC is made from 17-4 heat-treated stainless steel bar stock with a black oxide finish and will fit all barrels using 1/2x28RH standard threads.

The BattleComp is bad ass, you should check it out. Buy one here.

Here’s an older video showing a 1.5s performance:
