Filipino new show News5E reported on a raid on a crew of guns-for-hire by the National Bureau of Investigation. The cops found a nifty-looking suppressed .45 ACP submachine gun modeled after a M4 Carbine.
The gun designer looks like he was also party inspired by H&K. The sight rail on the top looks similar to a H&K G36 and the foregrip placement resembles the famous H&K MP5K.
Thanks to Chester for the tip.
