If you had it set at the height for irons would it interfere with left handed shooting?
i just held the rifle into my left shoulder, then folded it and if the stock is folded to the third position of 6, then my pistol grip hand is clear of the stock, and flipping the mag release and mag changing are no different than normal, actually much easier than right handed use.
i assume when you ask about height for irons, you want know if the stock is too high to align with them?
as it is now, when comparing the original stock over top of the ar stock, the ar stock is about a half inch higher comb than the original.
i will take a pic of the ar stock right now, and set it to the lowest position the adapter will allow, but i can't align it with the rear leaf as its removed and a pain in the arse to remove again.
