It's not so much the length but more the guage of the barrel and also the pics I have seen (the 'drawing' I used is a bad example) the end of the barrel is slightly tapered. I've never been a big fan of the stock Tamiya 105mm barrel. It's just too thick.
Not a personal attack, just an opinion.

Ah well, you have the advantage of me there. The only photograph I have access too has a cover on the muzzle, so I can't see the taper. I will bow to your greater knowledge.
