The AR has an optical sight. The bolts don’t lock back on AK’s.
I can see the optical (I think). I have Eotech holo’s on my AR’s - before the boating accident. HOW does the rear optical see through the front fixed iron sight?
And buy the man a two-point sling!
The black gentleman’s carbine doesn’t appear to be an AK. (but I don’t recognize the rifle)
