I think what Mr. Campbell is referring to is that there are none of the bells and whistles that typify the "standard" ATA style of preferred trap gun. Refreshing, actually. Makes me feel better about all those flat ribbed guns I have.
Here is a link to a nice site for int'l shooting. Has a link to the ISSF rules down the page a bit.
http://www.bunkershooting.com/tyro.htmlLike TW mentioned about the front sights in another thread, Perazzi had those florescent things on their guns in the late 60's. Several of the ones here still have them but the ATAers were quick to yank them and tap in a Bradley. Actually NBD to me since I don't see it anyway but the lost aesthetic is bothersome, innt?
