If you drop your gun upside down from a few feet or catch the feed neck against a solid object while sprinting. those most prone to cracking or breaking are the Spyder plastic feednecks. Having a metal feedneck is less likely to break than anything else.
generally feed necks break when either the loader is too heavy and too much side to side motion is applied or when the feed neck is plastic and is hit hard on something. Generally the best feed necks are metal and clamping.
Most systems will fit adjustable feednecks. The only major size differences are .50 caliber hoppers, and the tippmann cyclone hoppers, which have very large feedholes.
No.
No, they will break and you will be injured.
No. Only if you are VERY far away, the paintball may not break at all.
Break Beam Eyes are sorta like headlights. If a paintball crosses into the "headlights," only then will it fire. This prevents any breach breaks.
can you? yes, but it does matter which kind of window, a typical house window you can almost all the time, car windows are a little more robust and you typically can not, the windshields are very strong and I have yet to hear of a case where a paintball broke one
They will "fit" but they will not fire correctly, and will break when the bolt tries to push two of them at once.
because freezing causes brittleness, it would break.
One can find discounted paintball accessories from Just Paintball, Paintballing, Discount Paintball, Zephyr Paintball, Outpost Paintball, Paintball UK and Armed Paintball stores.
Most people suggest you turn your velocity down and dry fire a few tanks to break in the spring. Any marker will shoot better after its break-in period.
It's a barrel for Tippmann paintball guns and only Tippmann guns. It specializes in a flat trajectory, though suffers in accuracy. How it works is it adds backspin to the paintball therefore shooting it in a flat trajectory. Tippmann argues that the barrel adds range and while it is true that the paintball is in the air longer than a standard barrel the problem is that because of the backspin the paintball looses speed as it goes, so right around there a paintball from a standard barrel hits the ground is where a paintball from a flatline becomes useless as well as it will not have enough speed to break on anything.
