Adjust to any paint, get a new gun sell your back buy a new one
Takes at least 15 minutes to figure out what insert to use
I here the inserts bend if you sit on them or step on them.I dont do this, they work perfect when you put them in the barrel and shoot. some people say they dont shoot through breaks, I havnt had this problem. I used to use a an aluminum freak kit then I left paintball for a while and now there are so many kits out there and everyone bash's the smart parts kit, why??? Cuz it was the first one out so all else is compared to it. You probably will never use 3 of the inserts, who cares Id rather have them instead of not. the fact that you can buy different lenghts is awsome, and when you buy a new gun just buy a new back, with the dye or any others your screwed. If you use a decent paint its easy to match to an insert, if you use crappy paint you shouldnt be looking to buy an expensive barrel kit, save your money and shoot better paint!!! I know all paint isnt perfect but it should atleast be round!!
Maybe Im old school, but playing on and off for 17yrs now I have always found smartparts to be either the best or on par with the best and I still feel this is true. There are a ton of dye loyalists and evil lovers but alot of these people never owned anything else, my advice is if you get the chance to borrow a kit from someone do it and youll find this kit on par with the best. after all smartparts set the standard yrs ago when making the freak kit. nothing is 100% perfect but this is close as far as barrels go, i only wish a stainless back was available for my g7 fly.
