Ever have trouble with the quad on/off o-rings?
I was playing with my EP mag last weekend and the on/off hung up on me. The quad o-ring was mashed up. I thought "no problem, I bought spares". I pulled one from the pill bottle I had stored it in and put it in. Fired up and ready to go. Step on the field, and it dies. Same problem. All of them have lost their elasticity and my last one is even a little sticky. These have been in my possession for four years, and the one was fine for about 20,000 cycles in that time. It's like I hit the end of shelf life on these in a big way.
Anyone else notice that problem?
