These are add-ons to markers. Drops are for the ASA. These are mostly for looks, though some say it balances the gun (i personally do not believe so). Rails on on the top of tatical markers for scopes and such.
If they both have the same rails, yes. Rails are usually Picatinny or 3/8 inch.
as soon as the paintball leaves the barrel, the paintball begins to be affected by gravity.
Since it has weaver rails, all you need are Weaver scope rings. An offset mount will help too.
It depends on the Model, but most have 7/8 weaver rail.
In general scopes are not very useful in Paintball due to the relative inaccuracy of the Paintball itself and the tunnel vision effect of the scope. but if your Paintball gun had weaver or 3/8 rails, you can mount whatever scope (or sight, a better option) you wanted on it
Yes. without rails there is nothing to mount the scope (and scope rings) to.
No, but any drop forwards with the standard two hole fitting will work.
No. It does not have any rails, nor is it accurate enough to need one.
If by drop you mean it drops quickly in air when fired, then yes, your gun is almost out of CO2.
"Weaver" is a certain size rail that is skinny at the bottom, and thicker at the top. It is the standard mount for most Red dot sights and scope rings. There are also hand-grips, flashlights, lasers, range finders and grenade launchers that fit these rails.
A paintball, that is regulated, can travel at around 300. The time it would take to drop depends on the height of a person, but It would end up around 300 feet.
