why does it guarantee it? What if my barrel is recessed in the stock and butt to muzzle is shorter than 660 but the stock is over 660? Again I keep getting different conflicting answers. Can you picture what i'm asking? I might have to draw up a diagram to explain it because i'm probably not doing a good job of it
Overall length is overall length. End to end, no matter whats on the end (except a removeable muzzle device). If the stock is 660mm in length or longer than youre gtg. If you extend the forend past the muzzle then the muzzle isnt the end of the gun anymore now is it? Hook a tape over the buttpad and measure to the forwardmost point of the rifle not including muzzle device. Normally people dont extend the forend past the muzzle and I have no idea why anyone would but in that case you would measure to the end of the forend or whatever is out front.
