In looking at 14.5 or 14.7 inch complete uppers that state they are M4 configurations, do I assume they are carbine or mid length gas systems?
I ask because I am running across descriptions on different websites that only say M4. How will a 1/8 twist function in a 14.5/14.7 middy? I do not want a 1/9...1/7 is ok though. Just curious about a 1/8 in that length. |
