Who makes a dissipator upper with a flat top? I love the look and feel, but I'd like to put optics on it, and still have the extended sight radius with my BUIS.

It says that it has a car-length gas system... I thought with the gas block being all the way to the front that it would be a mid or rifle length gas tube.

Nope, up front its just a front sight block, there is a gas block back down the barrel towards the receiver, where a carbine's gas block would be.

Bushy's always had the gas block in the carbine position if I remember correctly.

CMMG has Dissipator-type models with carbine, mid and rifle length gas systems.
