As the one that should not be named is no longer manufactured, for a larger calibre "bang stick" what would the assembled inteligentia choose instead. My three suggestions are 1: H&K G3 7.62mm, traditional and still in current production, once used by "them" in Ulster. 2: A bit more modern the H&K 417 also providing the power of the 7.62 or 3: A newer calibre (possibly the successor to 5.56) the Barrett REC7 in 6.8mm. If adopted this round will give nearly the performance of a 7.62 with the mag capacity of a 5.56. The last two are of course M4 clones with an improved gas system.
