E-Triggers - Electronically
controlled, giving you semi-auto, burst or full auto
firing modes, great for support role players who
just want to hold down the trigger and lay waste to
their opponents!
Double Triggers - Less effort
involved and makes it easy to walking the trigger
(walking the trigger refers to when your two fingers
are simultaneously pulling the two grooves on a
double trigger).
Triggers depend on your style, and how good the stock one is. Sometimes
triggers are hard to fire (they're kind of tough or stiff to pull
back on). Getting a new trigger that fires the way you want is such a great feeling. This is one of those 'test your current gun' first to see if it fits your needs. If not, maybe a new trigger is in order.
(Note: If you're going to be playing tournament speedball then
you will want to upgrade to a double trigger).
Here's a video explaining how to walk a
trigger, note the double trigger in the video
6. Sights - Rear & Front - Scopes & Lasers
You can get many different types of sights for your
markers. Sights are very popular especially for scenario
and woodsball paintball. Actually they're so popular
that the Smart Parts SP-1 can mount more sights and
rails then my age, well not that much, but you get the
picture.
You can add regular front or rear sights to help you with your accuracy.
Why not get a
scope? There are regular scopes,
night vision scopes and also scopes that have
green
or red
dot lasers to guide your
shot and make it more accurate.
You can acquire scopes &
sights that fit on to any paintball gun, or one's that will fit
your specific marker.
Video About Scopes & Sights (Note: Make sure to bust a move while you watch...you'll see what I mean.)
This is the part that attaches your hopper to your gun - holding the two
together. This is usually a very popular upgrade piece, because stock feed necks
can sometimes be flimsy and brittle and end up breaking within 1-2 days of play.
That's not to say all feed necks need to be replaced,
there are clamping feed necks available
and I suggest going for one of those above a regular
feed neck. The reason being, clamping feed necks
actually "clamp" to the marker, therefore your hopper is
less likely to detach after you dive behind an obstacle.
Some feed necks are universal, some may require a
specific paintball marker.
8. Regulators
Regulators
regulate air flow from your air tank to your paintball
marker.
Without a regulator, the air flows into your marker at an unsteady fashion
giving you inconsistent shots.
The regulator will
control how the air flows in from your air tank, making it smoother
and more steady -
giving you higher accuracy, as well as consistent distance on your
shots.
Some regulators can just snap on and work
immediately, while others are little more complex and
can be adjusted and fine-tuned.
9. Remote Lines
If having your air tank attached to your marker is
annoying, you can put the tank in your backpack or
attached to yourself, and hook up one of these 'remote lines'
to it. It will take your air and feed it into your gun.
Remote lines are great if you're going to be playing
extended periods of scenario paintball because it takes
a lot of the weight off your marker and puts it on your
back.
Another benefit of having a remote line is a
reduced profile of your marker, making it easier to go
into prone (laying down).
10. Electronic Boards & Chips
If you have a more advanced gun, chances are it has a
computerized electronic board in it. Upgrading your
board can increase how fast the balls shoot (some going
over 25 balls per second) to increased accuracy.
Boards & Chips also give you different firing modes, and different tournament modes already preset in the chip.
Not only do paintball markers have chips, but electronic hoppers also
have boards & chips in them to increase efficiency.
