IIRC the parts replacement cycle on a Mk48 is drastically shorter than a M240. Numbers popping in my head are 15,000 before bolt replacement and 50,000 on the receiver compared to 100,000 for both on the M240....I might be completely off, it's been a while. I mean, I can't imagine the Mk48 receiver having the same life as the M249 (Minimi for our Euro friends).Does anyone know how the service life and MRBF compare for the HK121, Mk48 and MG3?
That's incredible. I imagine most barrels would suffer some sort of distortion or complete failure if subjected to that.In my HK21E demos I would fire a single continuous 500 and even 1000 round belt cyclic, remove it w/o a glove, dunk in it water, reinstall it, mount an optic, load match grade ammo and shoot @ 1 MOA groups at 100 meters all day long, and I did this with the same barrel for years. No one makes military-grade barrels like HK.
