Closed Bolt VS Open

[Lohman446]

In steady firing positions (read vices) it has been proven that closed bolt is not more accurate.

HOwever, if you are in fact getting more accuracy from one type of marker than the otehr in hand held situations, by all means use it. This is not to say that closed bolt is more accurate or anything, its just sometimes a number of variables coincide to make one marker more functionally (as in not in a vice) accurate than teh other

No paintball gun is accurate. This is why we have force feed loaders and super-electros.

The FN303? less lethal launcher? How about no .68 caliper 3 gram projectile is accurate outside of a vacuum?

If i were to shoot 1 shot outta a closed bolt gun, and 1 shot outta a open bolt gun, which would be more accurate?

[t33kyboy]

Give up.

ahhh what the hell......Magman's right

Depends... under scientific conditions, given everything else being equal neither gun would be more accurate

This whole debate seems to be a carry over from submachineguns and the early days of semis.

An open bolt blowback subgun (ie STEn) needs a very heavy bolt to keep it closed until chamber pressures reach a safe level. The downside is that when the heavy bolt is released, it tends to throw the weapon off target. Equal and opposite reaction and all.

A closed bolt blowback subgun (ie MP5) only has the lightweight hammer moving at the beginning of the firing cycle.

The early days of blowback semis (ie VM68) seemed to bear out the same findings in paintguns. Compared to an Autococker, the VM68 moved around a lot during the firing cycle.

Nowdays, with ultra-lightweight reciprocating assemblies found in most of the open bolt guns, there is probably no difference at all.

But, it's always fun to perpetuate the Autococker mystique.

"On a cocker bolt goes back, bolt goes forward, then the marker fires when the hammer is released. That spilt second can allow the ball to roll forward.

Now on E Blades or Race frames the load time and firing time is shorter which honestly makes it closer to an open bolt. The only real "closed bolt" shot is the first shot on a Cocker. "


incorrect...when an autococker is cocked and has a ball in the breech, the bolt is in the forward position, when the trigger is pulled, the valve opens, and air pushes the ball out the barrel. then air is redirected into pushing the bolt back, a ball enters the breech and the bolt closes in the forward position again.

on an open bolt marker, say a spyder, the bolt is in the back position when it is cocked and ready to fire. when the trigger is pulled, it releases the hammer and bolt at the same time. as the bolt moves forward, air begins to come out of the bolt and pushes the ball down the barrel. once the bolt is fully forward, air pushes back on the hammer and recocks the marker.

incorrect...when the trigger is pulled the first action is the sear releases the hammer. The hammer going forward hits the valve firing the ball. From that point the ram is pushed back then forward loading and cocking the marker.

bolt goes back bolt goes forward....then it can be fired and the action starts again.

And don't forget that with markers firing 12bps+ theres going to be no noticable diff between closed and open.

except the faries... Closed bolt still come with faries...
pretty much useless faries... but faries none the less...
