Compact and Sniper configuration Edit
Is it a mistake that the compact version with the collapsed barrel is stated as a seperate variant rifle in this article? I think so, because the visual guide indicates that the barrel of the weapon is just retractable on page 156 in the part about sergeant Melshi. I think this way there is no indication of a compact version with a collapsed barrel. As for the sniper version the aricle states that the barrel is replaced by the cooling shrout. But isn't it the nature of such a barrel shroud (not called barrel itself) to be added to the barrel instead of replacing it? I won't change it since I'm just a guest but just wanted to tell the authors my observations. P.S. Corporal Rostoks box on page 157 also states that the shoulder stock is retractable too which isn't mentioned either.
Conecpt art Edit
I found this in the search for images of the A-300.
