No End Cap Buffer

After receiving my 2 used Tippmann Pro/Carbines in the mail I began dissembling them to clean the internals and check to make sure nothing was damaged. Under the guidance of a friend who has disassembled his Pro/Lite on several occasions and with a little help from this diagram we took apart the first gun and cleaned it throughly and reassembled it. Then we took apart the second gun but discovered their was no end cap buffer (a small rubber stopper that blocks the bolt from slamming into the end cap). Fortunately I haven't fired the gun yet but can/will it be damaged should it be fired without the buffer? Also, where can I purchase a replacement?

The buffer between the hammer and the end cap is just an "O" ring. It is there to cushion the impact of the hammer against the plastic back cap. The original back cap is plastic and stands up to situations where there is no buffer just fine.

There are come stocks that use a metal back cap. If you use that metal cap without the stock the force from the hammer impact will eventually crack the retention grooves in the marker shell...even with a buffer "O" ring in place.

If the back cap is the original Tippmann plastic there is virtually no danger that any damage has been done

Oh, I am sorry. I thought you meant the cap on the back end of the marker. If you were speaking of the front end cap, the side or bottom end cap or even the left, right or top end cap, please disregard everything I said. I obviously stuck my nose in with information that was clearly bogus for this particular application.

I have reviewed my full page schematics, at your suggestion, of the M98, the 98C, and the Custom Pro. I see now that my comment was based on misinformation due to my faulty memory. I  also see that the only buffer in the marker is referred to as the O-ring rather than the "O" ring. A careless and egregious mistake on my part. Again, I apologize for any confusion my off-the-cuff comments may have caused.

The buffer is an ordinary "O" ring...available at hardware stores, automotive parts stores, gas stations that do service, McMaster Carr, and about 14,000 different vendors on line INCLUDING Tippmannparts.com!!!

Yes! I have used a flat disk cut from a tire inner tube!
