I have one on a .223. One of the issues I read about is that you need to ensure the recoil lug contacts the aluminum bedding block when the action screws are tightened down-evidently, they're not all perfect. Mine does and it shoots very well. If you want to clean from the breech without disassembling anything, you'll have to cough up $10 for the extra low cheek piece. I put the detachable magazine kit on mine. Being a single stack, it sticks out a bit more than I'd like and wobbles a little, but it's working well so far.
I had planned on drilling two holes and installing Uncle Mike's QD sling swivel studs, but after taking the thing apart to see what I'd be threading into I was not impressed, especially at the rear spot. I'm too cheap to buy their $80+ push button swivel setup, so I put one M-lock swivel up front and ran the sling through the bar on the side of the butt.
Overall, I'm pleased with it.
