Well, you're ruined...
Did you notice how light it is? Open it up, look at the finish on the parts that never see daylight. Mine loves Black Hills 168s and FGMM 175s.
All you need are KAC 45 offset BUIS and the JP quick detach swivel plug, I've got two on back order, like $45 IIRC, best way to attach a sling to the front. Dustin at JP will hook you up.
Nice rifle.
