Since I'm stuck in the PRK I can't buy one of these out right, so I've decided to build one myself.
The final result will be a stock 20" A2 AR15, no aimpoints, no rails, no tacticool junk. That said I have 3 questions.
First, why does the government use a 1:7 twist rate where as most commercial AR's have a 1:9. Which is "better" if there is such a thing and why.
Second, has anyone dealt with CCMG? I've been looking at their lowers and they seem to be decent.
Finally, how much of a weight/balance difference is there between the heavy barrel uppers and the regular government profile barrel. I don't mind weight as my normal shooters are of the wood and steel variety, but if puts the rifle at an awkward balance I probably would rather have the stock barrel. Also, will the heavy barrel last longer than the government barrel.
