Default RX2 Re-Seal

I got my RX2 in the spring of 2012...seems like yesterday... It shot 895 fps with JSB 5mm pellets and continued to do so for a few years. I tried reducing ram pressure a bit and at around 800 fps found it a lot less harsh on firing.

It dieseled just a wee bit, and pretty consistently throughout its OEM build. I finally got some help to tear it down, and found the front of the seal face eaten away quite radically. In went a Macarri 426 bullet seal. I boosted ram pressure until I hit 825 fps, and got the cocking force I remembered. Lube used was exclusively Krytox AC42, a boron nitride, and rust inhibitor enhanced fluropolymer lube. It is smooth and has nothing to burn...

Do not follow the instructions seen on the web to pound any of the swaged pins in the cocking linkage out; leave all that connected to the barrel block and remove it as an assembly. I have no idea why anybody would take that bit apart; there is no need and why risk the proper re-assembly with re-using a 1-use pin? Bloody idiots IMO...

The job was easier than a Diana 34, and those nearly leap apart when requested. No spring compressor required!
