I tried out the Ko-Tonics upper.
All I have to say is it’s my bank account balance will probably not thank me for shooting that. It’s chambered in 6.8 SPC, which is a larger cartridge than I had imagined. It think it would make a fine deer killer.
The upper is light, really light, but felt recoil, a little while more than a 5.56×45, is still very reasonable. We had no trouble hitting the plates at 600 yards, sighting through Uncle’s EOTech. Joe Huffman was ringing the
500 400 yard plate from standing position using the Ko-Tonics equipped rifle.
