I have a lightweight accumark in 270 weatherby that I bought when they first came out.
I have had the trigger tuned but otherwise it's completely stock.
I have taken dozens of critters with this rifle,it has worked well for me. If you sight in 3 inches high at 100 yards,it is pretty much point and shoot out to 400 yards. I really like that,no need to fiddle with lasers,dots,turrets,or windometers,
Just get a decent field rest and kill stuff quickly.
If there is something wrong with the Accumark,I haven't noticed it with my rifle.
