>>7085093>>7085178Actually on further examination they appear to be Combat Brick LSAT Experimental Lightweight Machine Guns, with the foregrip removed, scope switched out and over half the box magazine chopped off, that last detail is what I was stumbling over, but mystery solved heh.
I should gently curse you anon, just pulled the trigger on an order with that store for that set and a couple others that caught my eye. Anyway, no such thing as too many guns.
