Would someone please ID this rifle?

Had a co-worker as me what the soldier in the foreground was using, and I had no clue. Thanks in advance!

H&K G3 with the fixed stock and later-issue polymer stock/handguard kit. 7.62 Nato (.308), 20 round capacity. Semiauto and fullauto capable though VERY hard to control on full auto from what I understand. Made in Germany and license built in a few other places I think. Been in production since the '50s.
