I've shot several hundred rounds through my buddies mkIII and it is the nicest shooting. 22 I've shot.
Made me kind of regret buying my Beretta neos a little. Except for the price.
The mkIII target has a fantastic trigger.
I like the Buckmark but have to go with the Ruger, in fact I have a Mark I, Mark II and Mark III!
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.

A nice thing with both the ruger and Browning is that you can buy a speed loader pretty cheap and trust me you will want one lol. One other thing I think the buck Mark come with one mag while the mark3 comes with two.
Rain, snow or sleet.... Mud, sand and dirt.... My GLOCK will work ;)
