Looking for a SBR kinda like the DPMS Kitty-Kat. Only difference is Have a flattop without the traditional 'A' frame gas block. No more then an 8 inch barrel and free floated. Probably with either Eotech or aimpoint for optics. And most likely with suppressor added. Anyone know about either the DPMS 'Kat' or comparable system? Would like to get this order going asap.
