Why so much work to put an expensive and heavy kx3 on there anyway?
I run a linear comp from another manufacturer on my 7.5" and it does the same thing for like 40 bucks.
Some folks have their mind set, others look at all options. I'm not a fan of the KX units, but it's not my build. If you're going short, keeping it light should be a consideration. 10.5" 8lb gun defeats itself.
