Not really, in fact, many players use the Dye backs and a Proto tip.
They are very similar (as Dye owns Proto), but the Dye UL is much lighter and offers slightly better accuracy. accuracy is determined by paint to bore match and paint quality, depending on the paint you use the proto could very well be more accurate, as for the two barrels the UL is not much lighter, if anything it is very minimal and i have yet to see that anything besides the logo and a little of the outward shape is different between these barrels
99.9% of all guns made in the last 14 years have removeable barrels.....however they use many different "threads" on the barrels and you must match the new barrel to your old barrels "threads" Most common Threads are Autococker Tippman 98 Tippman A5 Spyder and Impulse The most common is Autococker (Dye, Proto, Evil, Infinity, Automag, and Eclipse use this thread)
they are pretty much identical, both lightweight aluminum 2 piece barrels, take your pick
They are basically the same company just different names. Their products are nearly identical. There is even some speciaulation as to Proto discontinuing the PM8 because Dye wanted to use that is "new" technology for their guns
Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.
