Barrels
All American-AA barrels will increase your accuracy big time. AA will also significantly quiet your gun. The drawbacks are the gun has an arching trajectory, which if you are not used to, will hurt your accuracy. Accuracy is still top of the line once you get used to it.
Average price $85
Tear Drop-will give relatively same characteristics of AA barrels. While Tear Drop barrels long-range accuracy is reportedly not as good as an AA, I've heard Tear Drop barrels are significantly quieter then AA.
Average price $65
Progressive-Same as the Tear Drop minus the fancy porting.
Average price $49
Tippmann Sniper-I was greatly disappointed in the Sniper barrel. The accuracy wasn't bad at short to medium range, but the ball veered off at long range. Longer stock barrel really. My recommendation would be to buy another barrel in the Sniper's price range.
Average price $40
Dye-Dye have been praised as, excellent top of the line barrels, and they live up to the hype. Dye's give excellent long-range accuracy but are also beleaved to be over priced. Other barrels will give comparable performance for less cost.
Average price $105
Eliminator-a step down from Dye's in the accuracy department, but are much lighter and quieter.
Average price $65
Power-this gives just a slightly better performance over the stock barrel. Not really a good buy, but better then the Sniper.
Average price $45
Armson-In two words, RIP-OFF. These barrels give good short to medium range accuracy but long range accuracy is awful. Plus an Armson barrel is LOUD, definitely not worth the hefty price tag. I have had MANY questions about this barrel. THIS IS NOT THE NEWER PORTED BARREL. This is the older model.
Average price $85
J&J-There are too many different types to give any kind of summary. I do know that J&J's quality control leaves something to be desired, but their variety of barrels might make up for that. The Stainless Steel, Spiral Ported with whisper brake barrels is recommended.
Average price $35-$85
Bolts
Note: it is widely believed that aftermarket bolts are not as good as the stock bolts. Plus aftermarket bolts tend to mess up your gun and/or barrle. You might be wise spending your money elsewhere.
Venturi-The widely popular and effective design generally increases performance, but for the most part not with Pro/Carbine. I've heard (and seen) Venturi's break massive amounts of paint, and heard they can get jammed in AA barrels, but have also heard players praise their Venturi. This product is like rolling a dice.
Average price $25
Starfire-The Starfire design is very poor. You will probably be better off with the stock bolt over this piece of garbage.
Average price $30
Rimfire-Now finally some good news. The rumor has said that the Rimfire will increase range and accuracy slightly, and without all the screw-ups. A $25 price tag might not make the Rimfire worth the money however.
Average price $25
Cyclone? -I've heard rumors that there is the famous Cyclone bolt now for Pro/Carbines. Whether these rumors are true remains to be seen to me. I haven't heard any performance info; feedback would be greatly appreciated.
Average price who knows?
Grips
Stock grips-The grips that come with the Pro/Carbine are somewhat large, and many players don't like the "battle grips" so they look to upgrade their comfort.
.45 grip-These are very popular in the paintball market. They are smaller in diameter then the battle grips. You can also get Hogue wraps around the grip to give you comfortable and cool looking finger grooves.
average price for base .45 $15
average price for .45 with Hogue wrap $20
Tank Adapters
Vertical adapter-For those who like to shorten their Pro/Carbines, or play indoor or speedball games where maneuverability is an advantage, there is a vertical CA adapter available. It relocates the tank from bottomline to in between the trigger and forgrip at a vertical 45 degree angle. There is another one that comes straight down at a 90 degree angle.
average price $35
Remote-Players who want to shorten their guns without having all the weight in the middle usually get a remote. Remote relocates your tank from the CA adapter to a harness located on your back. You can either buy a steel hose or coiled hose (latter looks like a phone cord). Also you can buy a gas-thru stock if you want something to rest you shoulder on when you shoot. I recommend the coiled hose (better in cold weather) and the adjustable gas-thru stock, which adjusts from 8" to 12".
Coiled remote average price $52
Steel remote average price $33
Stock average price $25
Adjustable Gas-thru stock average price $40
Expansion Chambers/Regulators
Backbottle Expansion Chamber-Taso made this baby specifically for the Pro/Carbine. From what I've heard of it, it's pretty good. While not as good as those Mega capacity EC, combine the backbottle EC with a regulator and you got a combo that will keep liquid out and give you more consistent velocities then any large expansion chamber on its own.
Backbottle average price $35
Deluxe Expansion Chamber-This is the same as the backbottle, except the Deluxe is located in by the trigger and goes at a vertical angle. It also is bigger thus making it more effective.
Deluxe average price $75
KC No Hot Shots/RG-1-If you want consistent velocities then a regulator is a must. Regulators give guns extremely stable velocities, which means improved accuracy. With either the KC No Hot Shots, the RG-1 or Palmer Stabalizer your velocity will be +- 2-4 f.p.s. variances. Definitely worth the money, and probably a must for tournament play.
Average price $70
