I have 2 Blackhawk Cheek pads (with zippered pouch) on both my wife's StealthII and my M700 VSF for our sniper games. For what we want to do, they work well. Easily removed for cleaning the bore, since the cleaning rod rubs against the top of the cheekpiece.
I'm not ready to drill holes in my HS Precisions stocks to install Rooster33 cheekpieces like on my other 2 Norinco M14's.
I cannot justify a new HS Precision stock for over $ 500 USD with the adjustable cheekpiece, not with my son in University.
Oh yeah, I've got an Eagle cheekpiece on my M700 .223 Earth pig Assassin Rifle (groundhog rig).
Find out what works for you !!
Cheers,
Barney
