Captain O-Ring - 3X Oring Rebuild Kit for Smart Parts ION

I absolutely love the laminated oring sizer! My wife seen me playing with our guns and wanted to help, since this was her 1st time seeing the internals I showed her everything I took out and she popped the oring off found what size from the chart and replaced it with the correct oring. I lubed it and reinstalled it, she had so much fun helping and learning thanks to the chart.Price was great, I told a guy at my local pro shop how much I spent on a 3 rebuild kit he guessed $50 since that's what other team (5 rebuilds) kits go for, I told him the price he assumed I got it 3-5 years ago when smart parts was going under.Shipping was fastI'll definitely be buying 1 of these for all my guns

Appears to have all of the o-rings stated and comes with a heavy coated paper size guide in the bag to help with identifying the proper o-ring and location it belongs. I haven't had to use any of these for my Ion yet, but I did a brief overview and believe these will work perfect.

I bought this for a rebuild of my 8 year old Epiphany, however after swapping the O-rings on the bolt my marker started leaking air from the chamber. Even after double checking the diameter of the O-rings and trying other sizes I couldn't stop the leak. In the end I had to put the old O-rings back on the bolt.This O-rings were of low quality compared to what came with the marker, and the sizes clearly didn't match. This kit is useless for replacing bolt O-rings.

Good price.

This package covers almost all the needed O-rings. It does NOT supply the elbow fitting O-rings.

Just what I needed. They also worked for my friends gun which is not a Smart parts gun!!
