I have a Sumatra 2500 that needs some work. The check valve went out so I added a foster fitting with a one way valve in it. That works nicely for that issue. But I blew the burst disc and it leaks from the muzzle end of the middle air tube air tank plug where the burst disc is. Air Venturi sent me new burst discs but they were too small, and I have tried 12mm steel discs, steel disks with an o-ring, and steel discs with an o-ring and one of the AV burst discs but I still have a leak there.

I have an African Air Ordinance power upgrade kit installed, and before I blew the burst disc last week I was getting 1280 fps with 14.3 gr. CPHPs and 1171 fps with 23.4 gr slugs for 71 fpe.  That kit cost over $300 shipped to me.


I would get another air tank plug from AV and another front sight assembly since I have beat mine up a little bit, but I have already spent so many frustrating hours on this gun I am just done with working on it. I love the gun but sometimes you just have to stop before you mess it up any further. It has taken a bit of a beating from my taking it apart and putting it back together over and over trying to get this leak fixed, but it can be made to work again. The parts it needs to get it back into shape are:

This should top the current leak since it is the whole tank plug assembly including the burst disc.

Not necessary, but mine is beat up

Not needed with the 2nd foster fitting I have on it now but needed to put it back to where it was originally.

I also have a moderator, the original fill probe and probe air tank assembly, and some old valve parts left over from when I installed the power upgrade kit. These will be included.

I am asking $400 plus split the shipping. I have a couple of air gun boxes from some of my other airguns and I can take the stock off the Sumatra and ship it in a smaller box than I could if it were in a single piece. These things don't often come up for sale. I accept Paypal.
