Just ordered  one from Olympic.  Anyone have any input on these?   I currently have a PCR4 that supports a Leupold M4 CQ/T.  The PCR4 with this set-up will put 10 in a 1 3/4 at 100 with random shooters behind it.  NO KIDDING.  I almost opted for the flattop upper receiver and utilizing the barrel, but thought I would be better off having a short range set-up and a med range set-up.
I know there are not a lot of OLY fans out there, but this thing really performs.  I hunt yotes with it, and have confermed kills out to 375yrds with my current set-up.  Any input on the K8 model would be greatly appriciated.

My K8 Oly Rocks, bagged 23 Coyotes with it this winter...kill shot ranged form 75' out to 400 yards!
I went with the FRISH front hand guard, Harris Bipod, Ace stock and Leupold scope.

Thanks for the input.  I purchased, installed and testfired 2 16inch uppers last year for a couple of dog hunters last year, and the 100yrd groups were very respectable, right out of the box.  I only hope the K8 is everything I heard it would be.
