Anyone know where i can get a new barrel and or barrel lock for the mendoza rm-600 ive looked everywhere but cant find anywhere to order either of them, ive sent pyramid air some emails hoping they can help, still waiting on the reply.

PyramydAir is about your only choice- except trying to go straight to the factory in Mexico.

Well i have it rigged so it will stay in now, not near as smooth but it works. This happened in the process of tuning it, i hope pyramid air can sell me a new barrel for the RM-600, if not i guess it will be retired.

Another thing, mendoza sucks...the main spring was bent and ive only put about 500 pellets through this thing so im assuming it came that way.

There is a number of reasons why virtually no one sells Mendoza these days; inconsistent quality control, a refusal to modernize their way of doing business with both dealers and end-use customers, meaningless delivery dates- from what I've heard, the list goes on...

Pyramydair does have Mendoza springs.

What exactly failed with the "barrel lock"? A photo would help.

im not sure what exactly ive got it in there now, but it came out and was too tight to go back in...doesnt make any sense i know, i hammer it all the way in thinking maybe it was slightly tapered or something but i put it in all the way and it never got any looser, so i got it out with some vice grips and and hammer, worked on it with a dremel for a while and got it to fit back in.

I think I know how to fix your problem. I have a mendoza RM200. I've tuned it several times. When you remove the barrel pin the lock comes out. The pin holds it in the right position. You need to compress the lock into the end of the barrel when you reinstall the pin. The lock has a flat side which needs to line up with the pin. Lube the lock before you put it back together and you should be good to go. If I understand you correctly, you used a hammer to put it back together. You may have damaged the barrel pin in the process. Pyramyd air was carrying Mendoza parts but they are out of springs at the moment. Good luck. Let me know if I can help you.

If you have a pin that has been removed but doesn't want to go back in then you can put it in the freezer for a few hours and then try and reinsert it. This will make the pin shrink a little so it is easier to reinstall. The Navy uses this method for the exact fitting of press fittings.
