New HK121 Machine Gun

One of the lessons learn’t during the recent wars in the Middle East is that the 7.62x51mm owns the long distance engagement. The problem with 7.62mm weapons is that they are heavy. The new HK121 is a next-generation GPMG that is designed to be as light weight as possible.

The HK121 is still a prototype. The Visier magazine article (cover pictured above) states that it is a new design despite the external similarities it shares the the MG4. It weights just a few pounds more than the MG4 making it much lighter than the FN MAG / M240.

    There really isn't any reason to get rid of the MG3, it' s proven itself like the M2HB of the American Army. The Americans should rather dump the SAW in favor of the MG3, and get rid of the women in the army--which are the reason for all the concern about weight anyway.

    Well it looks like a nice MG. but will it have the same pschycological effect as the MG3? That gun has proven it self for 68/9 years [Counting MG42, bascily same thing] But this new gun looks pretty intimidating.
