Site Mfg is a company that makes OEM carbon fiber products for industrial and miltary equipment, and a few years ago they broke onto the paintball scene with Stiffi Carbon Fiber Paintball Barrels. In the quest for lighter weight aluminum can only be shaved so far down before it loses its structural integrity. Carbon fiber is so featherlight it has to be held to be believed yet still rigidity and strength. It is resistant to thermal expansion, meaning expansion or contraction due to heat or cold is negligible.

The carbon fiber barrels have a slick finish internally and are step bored with a smaller bore towards the breech for compression to get the paintball to velocity, then expanding to .695″ at the muzzle. This boring creates less drag and friction on the paintball and combined with the smooth finish helps shoot through broken paint. Often it just takes a couple of shots to blow most paint splooge out the muzzle so you can get back to reasonable accuracy without stopping to squeegee out the barrel, keeping you focused on your opponents and not your marker.

The carbon shaft are attached to precision machined aluminum backs. For the one piece barrels the shafts and backs are permanently attached and the back is machined to a stated inner diameter such as .689, .691 etc. For their multi diameter Stiffi Switch Kit the backs are machined to size and threaded to accept the Switch tip fronts. Even with the aluminum backs Stiffi barrels are insanely lightweight… the 23 inch model is only 3 ounces!

One common misconception about carbon fiber barrels is they crack or that the muzzles can get easily damaged. Well, I wouldn’t say its impossible but you would have to go way out of your way to damage a Stiffi… basically, you’d destroy any barrel with what it would take! One thing you do not want to do is use a fluffy swab or other fiber squeegee, as the carbon tends to grab the fibers and the results will be a permanent fuzz on the inside of your barrel! Only use rubber or silicon pull throughs and stick squeegees… however, given the nature of the finish and step boring you won’t need to do this too often.

We currently have Stiffi Carbon Fiber Paintball Barrels for most popular threads and diameters in 12, 14 and 16 inch lengths. There is also the crazy long Stiffi Carbon Fiber 23Inch Tippmann Sniper Barrel… don’t laugh. These are only 3 ounces and are truly one of the most quiet barrels I’ve ever heard! I have always said that 20+ inch barrels do have a specific advantage in many situations and one is to be able to spear the barrel through branches and leaves to take stealthy shots while remaining hidden and behind protective cover. This is the ultimate barrel for that role.

We also have the Stiffi Switch Kits in several popular lengths and barrel threads. Pick the overall length and thread that you desire and you get 4 sizing breeches to match up any paintball you need to shoot, ensuring the best possible accuracy.

If you already have a pre-existing Custom Products or Smart Parts Freak Barrel Kit and want to lighten up your marker you can get a Stiffi Stif-Tip for Custom Products or Smart Parts barrel kits and 2 piece barrels.

Site Mfg has been producing and refining the Stiffi Carbon Fiber Paintball Barrels over these last several years and have created one of the most desired barrels in paintball today, used by recreational, woodsball and scenario players like the Psycho Clown Posse as well as top tournament teams such as Stockholm Joy and Miami Rage. Yes, they are not cheap… but the most advanced toys in life seldom are !
