Nice purchase! The SOCOM barrel is a bit overkill as others have said, but screw it... it's your gun to enjoy.
"jammed" is very broad and non-descript. How did the M4s malfunction? You "clean and maintain" them, but were they properly lubed? In the maintenance records, how many rounds have been fired since the extractor was replaced? Were the magazine springs and feed lips inspected?
I understand that you may have had legitimate problems, but it doesn't help anybody to throw out broad complaints with no details.
Thank god/alien or whatever my Colt M4 jammed several times during weapons qual few weeks ago instead of a firefight. Did I mention a lot of them did. I don't know, maybe is the platform and not Colt, and yes we do clean and maintain them.
