Think so mate - its to see down my sights while still using a cheap hopper.

Just remember that if you put this on, you are restricted to either only shooting out one side of a bunker (if your hopper leans left, you need to shoot out the right) or else if you come out the other side you leave your hopper hanging out a mile. Instead you'll get on better tilting your gun to the inside and looking straight down the barrel, leaving your hopper behind cover. even if the gun is tilted it's still going to shoot in the exact same way.
although come to think of it, does the BT omega not come with an offset feedneck as standard? So the hopper will go straight up but it is moved to the side.
