barrels.. what's the difference
between a government profile and a medcon (CMMG) and standard?
Also, what are some pros and cons of lightweight uppers vs regular. What makes them lighter? Are they less accurate or more likely to become less accurate with high round counts? I assume lightweights are easier on the muscles, but I wondered how much lighter they really are.
I'm looking at ordering (and waiting) on an upper receiver group and didn't really know the difference. I know I don't want an HBAR, but I didn't realize there were so many other options. Jeez....
XD9sc and other stuff
