RT problem on A5

[thcdelta9]

Hi, I went to the field recently and my gun shot fine 3/4 of the day, towards the end this is what happened. I would squeeze the trigger fast once to only get one shot but it would rapid fire like a machine gun and only one paintball comes out. Each time i fire the trigger it machine guns and shoots only one when the sound was like 7-8 shots

Any ideas? I noticed the cylinder is VERY close to the trigger

Forgot to mention i even put the ROF down to a minimum and still does it

You out of air?

[thcdelta9]

no man, as soon as it started happening, i filled it up and it still did it..

btw, i was using CO2, i know my sig says AIR but that field didnt have AIR so i had to use CO2

[thcdelta9]

anybody have any ideas?

Sounds like low air to me.. not enough air for anything to catch (the rapid fire sound) and not enough air for the cyclone to cycle (thus one ball is loaded and shot).
Or a damaged o-ring. In my case, the rear bolt o-ring was ajar.

[thcdelta9]

I'll recheck all my internals again, any other specific o-rings that could be causing this problem? (I was full of CO2 by the way)

[thcdelta9]

OK, I took it apart checked EVERY o-ring, none are broken, i lubed em all up, same thing is happening

[bvdave]

its not low air, and its not the RT, its your sear or bolt, where the sear catches the bolt it is worn down, its 95% the sear and 4% the bolt.. 1% something really weird lol

if its teh sear its easy, you can get a ne wone for a few bucks, or you can just get a file and file it down where its worn to give it a new edge so it will catch the bolt again

[thcdelta9]

so the sear is a part inside the trigger handle right?

Thats for a 98, but an A5 sear looks pretty much the same

So i need to look for spots that are used up? The gun is brand new too, this is ridiculous, i checked the sear out, its still square, but i noticed the sear spring was crooked inside, dont know if that matters, but ill try out my gun later

[thcdelta9]

OK, after checking everything I called Tippmann, they said it might be a crack in the power tube. Has this every happened to anybody?

Edit: Man I checked EVERYTHING, no cracks in the power tube, no NOTHING

I guess it's the 1% weird you were talking about bvdave

i need help ;(

[bvdave]

can you take a pic of the ends of teh sear and post it? also maybe try changing the spring, if it doesnt look right that could do it too, its the top part that catches the bolt.. also if you have a camera get a pic of teh bolt where the sear catches it, if thats worn it could cause problems too.

last but not least (ive seen it takes up about half of that 1% weird) how tight is your grip on? if its loose the sear will sit slightly lower then it should, i saw a bt-4 sear.. same one as on a5.. get toasted when the markers almost new cuz he lost a bolt and jimmyrigged something ne won that held but not "uite" all the way to the top so teh sear wore fast)

Ive fixed this problem on more markers then I can count, and only that one time was it not the sear.. well it was the sear but it was caused by the grip lol.. so i guess it was still the sear..


also the 98 and the a5 use the exact same sear, you can swap em with no problem,

[thcdelta9]

The grip is snug, its in there perfectly, so i don think it's that, but i'll check it anyways, im gonna try my friend's CO2 tank tomorrow also to make sure it's not the tank (never know)

[Cajun_Shooter]

i had the same problem but with my spyder, the spring broke. now on my a-5 i have response trigger and i can't shoot anything but semi. yesterday they cut my spring bc it was shootin320. then the dude dials it down with that screw in the side. and now it doesn't shoot anyhting but semi. yea i would think it would be the piece that catchs the bolt

[bvdave]

it could be the tank if the pin isnt depressing all teh way (part of the 1% weirdness lol)

still.. get a pic of teh sear if you can, when its rounded its not rounded much, barely noticable even

[thcdelta9]

ok bvdave, i tried my tank and i tried my friends tank, and it seems the problem has gotten worse, now when i pull the trigger, the gun doesn't even stop, it just fires full out till i shut off the tank

any ideas with this new information? btw, ill try to take pics of the rear bolt and sear, but my cam is old and really sucks on closeups, so i dont know how they will turn out

[TheGoldenFlash]

I'm guessing its one of three things.

1. out of air, but you said it wasn't
2. damage to the macro line
3. Broken Sear

I hope its one or two because those are quick fixes.

[thcdelta9]

hey, you think it's the RT's macro line? I'm 100% sure it's not our of air so that is eliminated.. hell i'll make a list of what i checked for sure

1. Not Tanks or Remote lines (tried my friend's brand new line to make sure)
2. Grip is in properly
3. Checked all o-rings and even lubed them up
4. Checked Sear and Rear Bolt, the sear is still perfectly edgy, the bolt is rounded a tincy tincy bit, it's still very edgy (ill take a pic to confirm)
5. Checked for cracks in power tube
6. Removed RT and re-installed it, even checked o-rings on the RT screw
7. Unassembled and Reassembled entire marker

That's it I think

[bvdave]

the rt hose cant cause anything like that, its excess gas it has no effect on cocking in any way whatsoever and i cant see teh piston bouncing teh triger like that,

if its teh sear or bolt it gets worst teh more you try it, and you said it just did so its looking more like teh sear or bolt... you dont happen to live in ingersoll by any chance do you? lol

anyways show us a pic of the bolt, if its got a tiny tiny bit roundeed then its probubly that, or your spring under your sear not being strong enough, from what youve told us it sounds almost 100% its a sear/bolt problem, weather ist teh sear, bolt or the spring not holding the sear tight enough.. get us pics of all three if you can, sear, bolt and that spring

[thcdelta9]

actually i live in Toronto, hehe kinda close, I'll try to borrow my friend's cam cause mine is so crappy on closeups of small things lol

[Corrupted355]

It sounds like a valve problem to me. If you know anyone with an A-5, see if you can get them to lend you their valve for a few minutes. A gunked up valve could account for the marker not re-cocking.

Also worth considering:
* worn drive spring - if you store the marker cocked
* drive spring that's been cut
* certain stocks are known to have a drive spring seat that is too deep, resulting in lowered drive spring pressure
NOTE:{any of the previous three would could be evidenced by low velocity or having the FVA screwed out most of the way and/or RVA in most of the way}
* sear spring issues - misplacement, bad spring
* anything that might be causing too much friction between the rear bolt (hammer) and the marker body; IE: burrs, lack of oil, or debris

[bvdave]

toronto is pretty close :P you busy on saturday? im hosting a game at my field in ancaster if you wanna join, maybe I can take a look at your a5 then, if i cant fix it you got a backup? if not I can loan you a bt-4?

my msn is bvdave@flasc.com if your interested.
