H&K, huh?
Funny, the German Ministry of Defense has decided that the H&K 36, the standard Bundeswehr infantry rifle, is defective (lack of accuracy) caused by sensitivity to environmental heating and the use of different plastics in the receiver.
Might have been another company.
That’s the G36C - the short carbine version, much like the US M4 is a short carbine version of the M16. The regular G36 has been used all over the world and hasn’t had those problems.
The Germans need to bring back the G3/HK-91.
