A+ Lowrise causing chops

[pgaglio]

I recently put an A+ low rise on my Speed and have had nothing but ball chops since I installed it. I've tried using an Evo II with it, a Halo B (brand new with Z-code and rip drive), sensi on (all different modes), and sensi off. My sensi passes the drop test fine and the rod is clean. I've made sure the hammer is adjusted properly and I've also cleaned the ball detents and stiffened them by stretching the springs. The marker's battery is totally charged and the paint I've been using is fresh. I also bought an A-4 bolt, hoping it would help (it didn't). I don't know what else to do.

btw, I took off the A+ low rise and put the stock gated feed neck back on and didn't have a single chop using my Egg II and sensi mode 3. This whole experience leads me to the conclusion that it's the A+ low rise causing the chopping problems.

Anyone have similar troubles with an A+ low rise or better yet, any ideas for a solution?


Thanks.

I'd say the problem is that the rise is holding the ball stack in such a way that two balls are meeting right where the eyes in the halo feedtube are. The eyes are looking throug this gap, not "seeing" a ball there, and the motor will continue to try to load balls. That would be the only way I could see a rise giving you problems.
You could try to sand the halo some more, if it isn't going all the way down into the lowrise. If it is bottoming out, you could cut off the bottom of the halo to let it sit lower, and align the ball stack differently to allow the eyes to work.

It's a good idea except that I had the same chopping problem when using an Evo II and the low rise (with and w/o sensi). I haven't sanded the Halo neck at all because the A+ is a clamping low rise. When I put the stock rise back on and use sensi I get no chops. Wierd....:puzzled:

I had a lowrise on my speed and it caused issues, now that I'm using a CCM clamping midrise it is fine. Try the new A4's feed neck, I wish those had been out when I needed one.

i have this EXACT same frustrating problem today....

both my halo and revvy were both having problems, so i'm pretty sure its not an issue of the Halo Eye ...

this is my first time out since installing the A+ low rise - and i basically chopped every single ball ... and im not kiddin - i didn't play a single game, and spent 3 hours in the staging area tech'ing this thing.

[warpedx]

wow, just wierd. A+ boycott in the making? If a revvy is chopping with sensi, then i really don't know. I could count out the egg (it couldn't feed my iR3 with the rof set at 16), but not something as simple as the revvy.

Had the same problem with my A+ lowrise. I thought that it might have been the paint. Worr Paint Domination would chop (paint on the bolt and breech), but when I shot it through my '03 Shocker I would get barrel breaks. Has anyone tried contacting them to get a refund or has anyone tried the Check-it lowrise?

[alphakry]

as wierd as it sounds, i think it was an issue of the 1st ball in the stack, pentrating into the breech ... HOW, i am unsure ...

a) I have a4 bolt, to prevent rollback
b) it did it with the halo, it did it with the revvy, so it wasent an issue of force
c) i have no idea how a lowrise could have anything to do with this
d) yep ... im stumped ...

Actually, the inner diameter may be just a tad larger. This would allow the balls to be set on top of each other kind of diagonally. Sort of like a double column pistol magazine if any of ya'll know what that's like.

Anyways, it would place the ball in the breach just a little farther forward, thus allowing the ball above it to go just a little bit further down, and put it in the bolt's path.

Does this make any sense to anyone?

[warpedx]

Yes, that actually makes a lot of sense, and would be about the only way I could see it affecting chops. Unless there was something about the way the bottom of the tube was milled (threads sticking too far down maybe?)

This does make some sense to me. At first I thought the problem was caused by the Halo and force feeding, etc..., but then when I had the exact same problem with an Egg (with and without sensi), I was totally stumped. It must be some kind of allignment issue that allows the next ball in the stack to stick slightly down into the chamber and then get chopped.

My chopping only occured when I was rapid firing. Whenever I had a chop (which was about every 3rd or 4th ball with the A+), I was amazed at the amount of paint that was going up the feedneck. It was even going all the way up into the bottom of the Halo neck. This might be further support for your idea, which is about the only thing so far that makes any sense.

I also thought this could be the case. However, from what I could see (looking throught the front of the Speed with no barrel attached) both the A+ and the stock rise are seated in exactly the same place when screwed all the way into the threads of the body.

Weird.... I haven't had a problem with my A+/Halo at all. The inner diamater theory does sound good. And mine is slightly larger than the stock one.

I have an A+ low rise on my Speed and on my RatPulse... The only issues I would ever have was from double balling. Stretched the stock springs out and it fixed the problem for me.

yeah, I tried that and it didn't work.:angry:

[F5monkey]

i havn't had any problems with my a+ low rise with my halo b or egg II z board. i say if going back to the stock rise fixed the problem, then go with it.

good luck

sorry to bring up an old thread, but someone one pbnation was have a related problem and linked to this, and I had a flash of brilliance.

If you put a layer of electrical taped on the inside of the feedneck, then you reduce the area for the paint to roll around in the feed neck, and stop those feed neck related chops. Just a theory, but something to check out nonetheless.

[Biotron]

the size of the A+ hole is smaller than the standard feed... so that can't be the problem,
I think the balls are jumping up at High rof (no pressure from upper balls) so the sensi detect the ball, it jumps up, and when the ball comes down again he gets choped by the bolt.
the solution would be a gated feed, just like the standard feed ;)

but i still try to get my speed working with the A+.

the war is not over now !!! ;)
