A used stock Tippman is worth around $80-$100
Usually LPR's are used to save on gas usage and if your paintball marker can work with lower pressures (otherwise you may end up with an effect that is similar to "passing gas" where the gas just leaks out of your marker upon actuating the bolt - if your paintball marker requires your air tank to be using a higher pressure)
This is a Nelson 707. It was made originally for marking cattle or trees and was later adopted for the earliest games of paintball. It is the predecessor to the Nelspot 007 marker.
There comes a point in paintball markers, where you can only make so many improvements while meeting the standard of 300fps and a hopper feeding BPS limit. This occurs in the $1000 plus marker range, where the "Best" marker literally becomes a choice in how the marker feels in your hands (ergonomics and valve design). Some markers in this category are The Ego 10, Dm 10, the Luxe, macdev clone and Bob Long Victory. None of these markers have a significant advantage over each other, all are used in high division paintball tournaments, and all are on the leading edge of paintball technology.
Unless you have certain Angel models, High pressure air is fine.
Anything that is designed to be loaded into a paintball marker that matches the bore size of the marker (can be from .50 to .68 caliber, and typically would be paintballs filled with water, other liquids safe for use in paintballs, or "reballs", paintball-sized rubber balls used for practice and or training). Use of any other spherical objects are not intended and may damage the mechanical components and may render it unsafe to operate.
as long as your at a feild... dont go shooting people on the streets
It is used to improve accuracy of your marker by tightening the barrel and letting less air get around the ball and more pressure actually pushing it.
The first paintball gun to ever exist on this planet was the Nelspot 007. The funny thing was this marker wasn't made for the initial use of paintball, it was made for agricultural use. It wasn't until twelve players with Nelspot 007's discovered the wonder of "Paintball" and changed the world as we know it. At the time "Paintball" was known as "Survival," a game that was first written about in 1980 in get this... Sports Illustrated. But the first paintball gun to be used intended for the game of paintball was the NSG Splatmaster.
They are the same thing. "marker"is the preferred term used when talking to non-paint ballers. It is just a better way to speak in public so people don't give you weird looks or think of paintball as overly militaristic. At paintball fields either term is fine, though older players will probably correct you.
Less then 50 dollars.
Around $50.
