I also own a completely stock Proto SLG which rocks but my stupid field doesn't use air so i have to sell.
Anything that won't break if you drop it or squeeze it lightly. I would say anything except Canadian Tire or Walmart paint but that's the closest thing we have to a proshop or paintball store within thousands of miles. I use big balls or procaps X balls which are really good.
I have heard good things about this barrel, and I had to choose between this and a JJ ceramic barrel and I ended up choosing this. When it arrived I went downtown to get paint and Co2, yes, Co2. I came home called up my friend and tried it out, I was amazed, I was hitting a 4 by 4 from 90 feet away and only missed once when I tried to hip fire. (my fault)
I got my friend to try it and I stood in front and beside it and found it to be a lot quieter than all my other barrels. The barrel shoots great from far and close, if you can aim at something, you will nail it. I was sooo excited to try this out with my friends in play.
Stories of success:
First day of use:
Pegged my friend in the ankle from under a van he was hiding behind.
Won a Gatorade in a shooting competition with one of my friends.
Headshotted my friend when i was trying to flank him and he saw me from about 100 feet.
Headshotted my other friend when he peeked around a corner.
And nailed my first time paintballing friend in the ass when we were all rushing his base and he was running out the back door.
So lets just say I was happy with my purchase and my friends really weren't lol
I was using a tippmann 98 and Co2 but it shot straight as ever and groupings were as good as you can aim.
Great barrel, you won't be disappointed unless you buy the wrong thread lol
I had it in a 14 inch .689 bore barrel, and used it all day whenever I played. I haven't had a break yet, and I just sold it to the friend I shot in the ankle as I will be getting an SP1 so I can keep using Co2. I will give it a 9 because nothings perfect, but this is as close as ive ever seen so far. I often think about getting a freak or sly carbon fiber, but it`s only because they look nice, and my CP is accurate as hell, so I tell myself that.
If you need a light, extremely accurate, cheap, quiet barrel, this is it. Enjoy the headshots
