12.5" BCM, stock. I'm unsure which one to go with. I'll mainly be using it for classes, which would require rapid fire and also shooting at night under nods. Shooting wolf gold as my training ammo. Also what should I run under it? Currently I have a standard A2 birdcage, looking for something that interfaces well with whichever Thunderbeast can I get and when the can isn't on reduces flash as good as the A2.
Thank you.
