I have been wanting a 6.8 for a while now. I didn't know exactly what I wanted, but I am happy with this rifle, as it is my first ever build. It is a Para USA lower that I acquired in an even trade for 28 AR mags. The upper is a Bushmaster 16" M4 Govt. profile flat top that I got for an even trade for a taser x26.. It has a CMMG lpk (partial trade + cash for handheld ham radio), the old buffer and spring from my RRA SBR, and will be sporting an extra Nikon 3-9x40 Pro Staff scope I have lying around. I got $75 for the ham radio on top of the parts -$12 for the shipping of the taser in the trade. So, I am at a net +$63 for this rifle. When I got the upper, the gas tube was in backwards and upside down. I fixed that and lined up the barrel nut a little better. This rifle runs like a Rolex now. I will use this at the lease to hunt hogs and deer.
