Screw the AR platform...I wish there were bolt guns available in the 6.8!
No problem...
I built one a while ago for a friend. He really likes it and says the results on game are impressive...like a low-recoil lightning bolt.
The build is cheap and very easy to do.
I picked up a Wal Mart ADL and a few boxes of factory rounds in 7-08 and dumped out half the powder.
I told him it was an improved 6.8.
I named it the 6.8 GPC.
I didn't tell him what the "g" stands for.
