Very cool design! And for those who question the functionality of the silencer/bayonet combo, that silencer is going to give out at some point. And when every shot is going to give your position away it's nice to have something as a last line of defense This dude is prepared!
While true, untill he removes the silencer the bayonette is not only none-functional, it actualy degrades the accuracy of the rifle both by throwing of the weight even more than just the silencer, it also means the barrel has another contact spot where vibrations can effect accuracy.
If he has the time to unscrew a disfunctional silencer, he has time to put on a bayonette. Untill then, leave the bayonette in the sheet where he can get to it in a hurry should he need a knife.
I have to agree to the below...that the bayonet and the suppressor are not combat...sure it could be a QD silencer...but that doesn't help him in the heat of a fight: "Hold on while I unscrew my silencer so I can gut you"... That's really the only fallacy I see in this picture. everything else is badass, and I want one to guard my house and kill trespassers.
Perhaps put the bayonet on his chest as a tactical knife.
