Just a bit of knowledge gained over the years but by no means gospel, earlier Dye Ultralite barrels had ULTRALITE stamped down the side as well as DYE logo on each side. This meant they were the "standard" bore at that time when paint was CONSIDERABLY larger and therefore needed a bog bore barrel to shoot it.Hi Marco, i just rang dye and asked them about this because i was sure they were .688 and they said they were pretty sure all unmarked ones were .688 just wondered if you were maybe going off the picture off the website and had confused it or had some other info? cheers
