PS, the front rest is sand paper. It'll of course, mark your forend. My solution is a dedicated forend, flat, 3 inches, and oil stained. That way, when you want to sell it, you just knock the bottom smooth with some 240, then 320, a little tru oil, and you are good to go.
With lapua brass, berger target bullets, 332, match primers, etc. and a totally stock .223 TC barrel, I get REAL 6s to an occasional 4.
The most important part of an accuracy rig, beyond a good rest, it a SUPER trigger. Mine breaks crisp at 10 oz like a thin glass rod. Don't hump the grip, easy does it on the handwork aligning the shot, and with practice and a top notch barrel, 3s and 4s are routine for a competitor, and a journeyman like me can produce 1/2 inch groups most of the time.
One last thing, if you are shooting easy recoiling cartridges, consider a longer eye relief high power rifle scope at >4 inches. If you really want to go all out, compensate a .223 or some similar round with a high power rifle scope (side compensation only! so you don't ruin your scope!!!) Virtually no recoil, and WOW can you shoot tiny groups like that.
FWIW, hope this helps.
