Detailed Features 

The M.O.A. Trigger System lets you dial in pull weight and consistency for repeatable shot placement. The free-floating barrel cuts down on vibration at the muzzle, which translates directly to tighter groups. Controlled round feed and ejection handles cartridge cycling reliably, including under field conditions where dirty or damaged cases can trip up push-feed designs. The Bell & Carlson synthetic stock has a sculpted cheekpiece that puts your eye in line with the scope naturally, and it keeps the overall weight down. The hinged floorplate lets you clear the magazine without removing it. 
 
The rifle also ships with sling swivel studs and a Pachmayr Decelerator recoil pad, which takes the edge off .300 Win Mag recoil during a long range session.

The Model 70 Extreme Tungsten MB in .300 Win Mag draws mostly positive feedback, though the discussion is honest about the rifle's trade-offs.

Build quality and the classic controlled-round-feed bolt are the two things owners consistently mention first. The action cycles smoothly and the M.O.A. trigger gets credit for being predictable shot after shot. Accuracy at extended ranges is a common theme. The .300 Win Mag caliber handles larger game cleanly and holds flatter than most hunters need.

The main criticisms are weight and recoil. At 7 lbs 4 oz with a 26-inch barrel, this is not a light mountain rifle, and carrying it on long approach hikes gets old. On the recoil side, experienced shooters generally manage the .300 Win Mag fine, but the feedback is consistent that newcomers should spend time with it before a hunt rather than taking their first shots afield.
