Not trying to be a jerk, I'm genuinely asking, but what does this do?
No worries. It mostly just looks cool. All my other guns are pretty "serious". The Scorpion is my designated "fun gun".
I don't need recoil reduction and I spend much of my shooting time indoors. I have a linear comp on one of my SBRs, and it makes shooting much nicer. I also like the look where guns have a linear comp that starts under the hand guard. HBI doesn't make a slightly longer hand guard, so I made a linear comp that covers the threaded area on the barrel. I call it a "setback" linear comp.
Also, the factory flash hider allows a lot of soot to come back and cover the hand guard when I'm shooting dirty ammo. This will keep it a bit cleaner.
