H&K SL7 A comment on the H&K SLB 2000 mentioned that there was a hunting rifle that looked like the G43. The SL7 was basically H&K’s attempt to make the G3 into a hunting rifle. It doesn’t use the G3’s magazines but has the same roller-delayed system along with the front and rear sights. Also no longer in production. It bears a very heavy resemblance to the G43; whether or not H&K did this as a historic nod to German firearm history is unclear.
