All parts are new and Mil-Spec quality by an ISO-9001 Certified Cage Code military contractor to ensure the best quality possible.

This is all the parts needed to Change caliber from 5.56 to 7.62 NATO. (Some minor Mods to your receiver are needed and MGA can assist in these Mods to your existing receiver.) 

We can assure they are accomplished precisely to allow a trouble free reliable conversion that can be changed back and forth as desired. (The cost is very reasonable)

If you want the MK-48 to be a new dedicated weapon, the receiver subcomponents are available to do a Class 2 Build which will allow simple caliber change from 7.62 to 5.56 with parts swapping creating 2 weapons in one, (As is accomplehed in the HK-21E/23E series ) See pics below for the parts supplied for 3250.00 added.

What all has to be done to the M249 receiver in order to shoot 7.62? I guess it really shortens the life of a M249?

I saw a ad in a military publication talking big about the "new modular M249" and its capability of being converted between the two calibers. That was last spring and I have heard any talk regarding re-work programs or purchase of new guns that can be switched between calibers, i.e. "two guns in one". I wonder if actually testing didn't go so well.

Yes the M249 tears up 5.56 casings. I would think the 7.62 chambering would tear up the M249!
