Re: Barrett M107/M82A1
From my USMC days....
Love: Expanded effective range and destructive power, rapid firing rate, decent long range accuracy when material is your target, very high CDI factor at a dog and pony show.
Hate: Thing chewed up brass, jammed often, heavy and huge, trigger is horrible, very finicky, loud and concussive reducing any chance of maintaining concealment, constantly in maintenance.
Really it wasn't practical outside the defensive spectrum of warfare. You could take it if you NEEDED it, but you would be slower, louder, and bigger in doing so. IDF and CAS could cover anything it was needed for in open ground, but it has it's place in urban settings.
