Just got these rifles a few weeks ago from Ryan Kelsey... owner of Diablo Custom Rifles... The kryptek rifle is a 28 nosler.. defiance deviant hunter.. bartlein 3b.. manners eh1.. jewel... this thing is a laser and is better than a quarter moa shooter!! And the proof barreled rifle is a 300 rum... McMillan a3 sporter.. proof barrel.. jewel.. built on lone peak arms razor action... terminator t3 brake.... this thing is insanely awesome... no recoil at all and is shooting in the .1s!!! I'm extremely pleased with both rifles and will b having Ryan build all my rifles from here on out... he is a great gunsmith and a hell of a guy... quick turn around times as well! If you're looking for a true one of a kind rifle give him a call! Or get ahold of me and I'll get you a deal
