I need some help picking out orings on mcmaster carr, im trying to build a little repair kit for just in case

It would be more cost effective to purchase an already assembled kit from a trusted supplier/seller (on your favorite paintball site or auction website). However, if you wish to do your own, use the manual for your model and get the correct number for the different sizes for each rebuild. Or...if you just want an emergency kit for those that may wear out fastest, then order based on those attached to moving parts and assume the stationary ones are less likely to fail.

So oring monkey would be a better choice then?

Ive already purchased a kit for a different gun there but just wanted to see if its better buying in bulk

oringmonkey.com is your best bet for sure.

When ordering mcmaster you normally have to order the orings by the hundreds, so unless you plan to make alot of kits it would be better to buy one from oring monkey or captain oring.

I think so...unless you're making kits out of the excess to sell. I've not gone through huge amounts of orings with normal play. Even when I count replacing all orings in newly acquired used markers I still can't justify a bulk purchase of every oring size. If you lube at regular intervals and replace orings at the manual suggested intervals I still think you'll never justify a bulk buy of every oring in your gun. But that is just my personal perspective. Who knows, your mileage may vary. If you like to replace orings often I still suggest buying the ones on moving parts in greater quantity than the stationary ones, in addition to a few total rebuild kits, if you're looking to have a sufficient stock on-hand for any situation.

I did this and I think I missed a few sizes. Cost around $30 to have them all shipped. It's WAY cheaper by volume, but you really don't need that many orings.
Having 100 orings of every size sure is annoying, but I have TONS of them now to give to friends, or whatever.

oringsusa.com is a good source as well. They have a large variety of different o-ring types if you don't want to use regular buna. They will run you close to the same as a kit on say oringmonkey.com depending on what you select but you can pick out the ones you want.

I have bags of orings in my toolbox. McMaster is great, but then again spools are more picky about orings.
