Larry Vicker’s was sent some photos of the HK433 by a German fan. The HK433 is H&K’s new rifle. It is interesting that they are going with Keymod but the rest of the gun reminds me of the FN SCAR, the Beretta ARX 100 and the Remington ACR. Behind the magwell I see what looks like a bolt catch/release similar to the ACR. Beneath that it looks like H&K went with a lever style mag release.
