My three:

Marlin Model 39A .22 LR. This is the funnest, most accurate .22 sporter that I own. The fact that it was a gift from a close friend endears it even the more. I have a Leupold M8 4x on top.

Remington Model 870 20 gauge. I love hunting uplands the very best and find the 20 is plenty for them and easier on the random cottontail rabbit than a 12 gauge.

Winchester Model 70 Classic Stainless .30-06 Springfield. I bought this rifle at 18 years old. It was the first I ever saw with a stainless steel finish and a walnut stock. I have killed many elk and deer, along with many other critters. I could happily hunt big game with this rifle forever more. I have a Leupold VX3i 3.5-10x40 on top.
