I have a couple of questions:

Is that a 20 round magazine? It looks too small to be a 30 rounder to me, but I'm no expert and I'd like to be sure because I'm making a mod for
S.T.A.L.K.E.R. that changes how the weapons behave, and the SIG SG-550 model in it has a magazine of that size, but holds 30 rounds. I want to be sure that's wrong before I change it.

What is that on the end of the barrel? Is it a muzzle brake?
