Americans would never use a plastic gun, so the XM8 and G36 designs were doomed to be rejected from the get go. Buy nevertheless, the Germans themselves don't use the XM8...
Anyway the whole point of the XM8 was to be a test bed for a modular rifle system, for some reason nobody likes German modular rifles..... have any of you ever heard of the H&K 'GR' series? lol
But like any good test bed, it sometimes gives fruitful results. Has anyone caught on to the fact that the new XM25 "Individual Airburst Weapon System" was developed in part by H&K who designed the horribly cumbersome XM29 OICW?
