I recently picked up one of these in .308 to go with the ATR .30-06. Seems they are pretty much a re-named ATR 100 without the Lightning trigger.
The mechanic's appear to be same, but there are some cosmetic differences as the pictures will show.
It shoots rather well. Unlike it's cousin the ATR, it has been more finicky with the ammo. The ATR likes a variety of brands and bullet weights. I've only put Federal Power Shoks and Remington Core Locts 150's through the Maverick. It definitly favors the Remingtons. While I've only had about 20 rounds through it, its showing 1 1/2" at 100 yards with the Core Locts.
I was surprised at how clean the rifle was upon delivery. I dis-assembled it thinking that I might find some grit and packing lube, etc. Not so. There was an appropriate amount of oil and no grit. A quick wipe down with some Hoppe's and it was re-assembled.
Since the photos, I've mounted a 3X9X40 Nikon Pro Staff and Leupold Rifleman rings. Bases were provided with the rifle.
