Step 1: If you don't want to spend lots of quality time with a carbine OFF the range, be very VERY careful what you pick up from an individual at a gun show.
I really don't have any regrets about buying this carbine. It will cost more than a common commercial gun and I'll have lots of time in it. However, the new barrel should make up the difference.
Now, what publications should I peruse to find tips on making this thing perform at it's best?
I'm thinking about changing the barrel clamp while I've got it torn down. Is there one style that is more desirable for consistency and accuracy? The unit I have requires plenty of effort to get it over the nose of the M2 stock.
