Paint breakage

Any problems: We had to sand down where the oring closest to the barrel is, to make sure it didnt pinch the oring in the body. The nubbin needs to be a bit longer in the back to keep the rear oring on it.

For about 1000 of this it was Loaned to a Kid from DC ( sorry I dont recall your name off hand) He used it in the Big Game at Pevs. I am gues he shot over 1000, and I shot about 500 at the shop the night before.

I know he broke some paint but no real details, but I belive it was Operator Error.

This Nubbin I need to shave off some flashing so it would return after a ball passed. The nubbin was a tad fat at the nub end and was hanging a bit in the grove.

Well one other thing to remember is durability. That's one of the problems I encounter with my V/P nubbins. When they are old they can rust and crack with a little poke. Sometimes you bend them too far by accident and SNAP!, there goes your nubbin, and now you have to go find another one.

People should see how much the nubbins can take. By bending them in the warm, cold, trying to squish them, etc. I think this would show how the new nubbins and more durable then the old.

Gun type: Automag with retro valve
Barrels Used: DYE Boomstick, LAPCO BigShot
Bolt: Long Nose bolt
Loader: 12v revvy with intellifeed to z-grip:D
Air Sysytem tpye: AA Raptor rex 68cu 4500 psi
Air System Input: 850 psi
Installed: 11/14 just for fun:)
Approximate number of shots: 600 total, 300 in each barrel
Paint used: Marballizer, JT, and inferno
Bore Size: Who knows? Who cares? but they are all about .688 or .687
Paint Breakage: NONE
Any problems: Well the nubbin on the DYE boomstick didn't
appear to do all that much

and here are some more oobservations


I tested the nubbins on my DYE boomstick first. The Boomstick had the perfect size barrel o-ring slots. They were nice and narrow. Therefor I didn't experience the problem most others did with the nubbin being to short and the o-ring creeping down. I did however experience once problem. I tested this with 3 types of paint. some fresh Marballizer. some older JT paint, and older inferno. All 3 paint shot well with no double feeds but that was surprising. The nubbin barely sticks into the bore of the DYE boomstick. I did notice it did have some resistance and after about 300 shots there was 0 wear on the nubbin. The boomstick is very different to most barrels in the breach. Rather than being flat it is concave and acts as it's own ball detent with medium paints. I am going to test it with hellfire next time and see what happens. After the shooting test I grew suspicious of the boomstick. I took one marballizer ball and put it in the barrel. I then realized that the nubbin did have SOME effect but by applying little pressure I was able to get it past the nubbin and when I blew harder it flew out the barrel. This paint might of been a bit too small for the boomstick with is a .678 bore(calipers). Overall the boomstick seemed to handle it very well and DID NOT double feed so I was happy. I replaced the nubbin with the 3 others and I came out with the same results every time. I am still uneasy about that indent where the breach in the barrel meets the feed port.



Now I tested it on the LAPCO Bigshot. While the barrel o-ring slots are much larger on this barrel, the nubbins still weren't too short but just to be safe I added an extra o-ring. I did notice that after 300 shots there was a little wear but nothing serious and in the LAPCO there is no concave shape where the breech hole is. It's nice and flat. There were no double feeds and eveything went smoothly with all 3 paints. I was pleased. I blew hard and still the nubbin held the ball in place. Once I pushed the ball past the nubbin and blew surely enough it popped out the other side. Both barrel are near the same bore. I think LAPCO's for mags are a smaller bore for some reason when compared to LAPCO's for spyder. But that's a completely different story. Here is my feed back. I am a little confused though. From the pics I saw some people were having obvious problems with the nubbin being too short. Did I get the second batch of nubbins? I received mine in the mail yesterday and I sent my envelope in the day after the contest was announced but I don't live to close to IL.


So overall, in the DYE, the nubbin didn't seem to do all that much but it was still okay. In the LAPCO the nubbin was perfect and there were no real flaws. I didn't even need the extra o-ring but I thought I might as well seeing how I had a couple parts kits laying around.

[hitech]

Has anyone at AGD considered using a wire "holder" with a plastic ball "tip" for a nubbin? Seems to be that would work well, but then I don't design paintball guns for a living. :) Just curious.

BONEisAgod, your post is kind of useless here unless you provide some information about the nubbins. Nice gun though. I still wouldn't call it "(Tricked out the ***)"

This is for feedback on the new plastic nubbins.

When you get your new plastic nubbins this is what you should fill out.

Barrel Used: Smart Parts two-piece (very old)
Bolt: Long Nose bolt
Loader: 12v revvy with intellifeed to Intelliframe
Air System type: Crossfire 68
Air System Input: 800 psi
Installed: 11/12
Approximate number of shots: 1200
Paint used: 32 Degree Competition
Bore Size: I really don't know
Paint Breakage: One barrel break (not breach).
Any problems: None. Actually forgot I was playing with a replacement part.
Other: Rainy day, 90% humidity, 67 degrees.

Observations: I noticed that the first 10 shots over the chrono curved around as if I had previously broken a paintball in the barrel, but the barrel was dry. Don't know what that can be tied to; but the subsequent shots were straight.

The one ball-break was down the barrel. I am not sure if it was due to the nubbin (this break was within the first 100 shots of the day) or over-brittle paint. It cleared well and I didn't have any problems the rest of the morning.

[scenario skwirl]

only problem i encountered was that the orings didn't sit all the way in the barrel making it hard to get the barrel back on, sometimes stretching them pretty bad.

A special thanks goes out to Dubstar112 for sending me two of these. He is truly a generous fellow AOer. Thanks again Dubstar112.

I did try one of them this weekend in my Freak. Shot great no problems except for the short end that pops out of the back Oring when I removed the barrel. Otherwise it fit nicely in the slot with no trimming like some of you have reported. I had absolutely no problems with the thing except its just a bit too short. I fired a full hopper of Powerball pearl at targets with the thing. I pronounce...I LIKE EM!:D

A Magical thing did happen to one of them though. More on that later.;)

Gun type: E-Mag
Barrel Used: Stock, .691”
Bolt: Stock
Loader: TurboRev upgraded Revy, Warp Feed
Air system type: MacDev Conquest
Air system input: 600psi
Installed: 11-7-01
Approx number of shots: 2200
Paint used: 32 deg Competition (hey it’s only rec ball!)
Bore size: Med
Paint breakage: 4, all in the barrel, none near the breach
Before: dependent on paint weather, blah, blah
After: None due to nubbins
Any problems: The plastic nubbins are a bit too big to fit into my warp mainbody, with both O-Rings. I had to remove the O-Ring nearest the breach, and I used 2 O-Rings in the groove nearest the muzzle, to retain the nubbins. I also trimmed the boss on the back side of the nubbins, that contact the inside of the mainbody, to allow the nubbins enough area to flex out of the way of the bolt. I got the barrel jammed up pretty good in the mainbody, when the O-ring nearest the breach apparently popped out of its groove when the barrel was inserted. It was hell getting the barrel out in the field after a ball break. The barrel sustained some more damage where the barrel detent gouged the barrel along the track which guides the barrel. I Hate nubbins! :(

I broke a couple of balls out at the country club but I think I just need to sand it down a bit more and I think my bolt is screwed up and that may have helped with breaking thew balls

Thanks a TON for the feedback. We are making the changes to the mold now and the next batch should be perfect! I am going to float this post now so we can make room for other stuff.

Thanks!
