Has anyone else had an issue with blowing the seals out of the CCI pierce pin assemblies, or is it just me? Whether it's with the lever changer on the DSG or the screw-type side dropout on my Zeuses, I seem to lose these things an awful lot.

Last night I may have found a solution, or at least, a better alternative; remove the flat face seal, run a light bead of superglue around the outside edge of pierce "cup", and put a size-matched o-ring in there instead. With Leland 12ies, not only does it seem to seal much more easily (lever doesn't have to be set nearly as tight to seal), but I've ripped the lever open with 6 almost completely filled 12g's and the oring has made no attempt to exit the pin assembly. Doing so with the stock CCI pierce seal would blow out almost every time if I didn't slowly open the lever and allow the gas to purge gradually (obviously not ideal in a firefight).

Just curious if anyone else has encountered this or if it's been limited to me, myself, and I... I seem to remember DM6Rocker losing one of his at the last NJ MCB get together, if I'm not mistaken, leading me to believe we are not alone.

Definitely have had this happen. Can't remember who did it, but someone used a type of glue/resin(something that didn't dry completely hard)/can't remember exactly....

Anyway, he dripped it in slowly, letting it dry into a new, very durable seal. Sounded nice.

I vaguely remember the thread I think, searched all over but couldn't find it... I think it was RTV sealant or something... Maybe CJ? Either way my superglued o-ring seems to be holding for now, I'll put it through its paces at the MCB g2g this Saturday and see how long it lasts.

It's just one of those really pesky problems that I find really annoying personally. Nothing makes me more angry than getting into a fight and getting left defenseless because of some stupid failure. I was inches away from carving into my wood grip to route macro through it and use the gun as constant air but figured I'd try the o-ring trick first.

And when the oring gets too worn you just goo-off it?

[CJOttawa]

Yeah, that's me. Check the Redux section for anything on pierce-pins and seals. Putting a bit of epoxy behind the seal should keep it in even if you dump a full 12-gram.

Try drilling a small bleed hole just above the seal surface at 90 degrees from the slots.

Granted I haven't tried it yet, but it's still glued on to a smooth metal surface, so I'm expecting and Xacto blade wouldn't have a problem picking off any remnants. Besides I'm not sure how long it would take to wear out as it's using compression for a seal still, so it isn't like the o-ring should really wear much. Degradation due to freezing might be another story though.

I was thinking of that too. I'll see how the o-ring trick works out long-term and if it doesn't hold up I'll try epoxy and the bleed hole on a stock seal.

Stop ejecting full 12 grams. Bit of a waste isn't it?

I have had it happen in the shop too, but I am intentionally ejecting partly full 12 grams since I don't have time to shoot them down when testing. Its really related to the speed at which you can eject using the lever. There is no bleed down. Its just GO! The gas goes behind the seal to vent and just blows it out.

Its possible to do it with a bucket changer as well.

[PistolRogue]

Well I tested with full ones to make sure it worked. In play I've had them blow out with partials too. One of those things where if I know I'm about to dive headlong into the grinder I'd rather go in with a full than half-full 12ie loaded up, you know?

I've had a big problem with it too. Fortunately, I generally only dump a half-full one between games, so I have time to let it bleed for a second, but it's still a pain. Going to try the RTV trick soon.
