I had leaky mags for Rawdon... Fired a few rnds through each of them, solved the problem.
Hassn't come up again since, I would like to replace the valves eventually. I already replaced some of the O rings with larger ones from Canadian Tire to solve some blowback issues, mainly your bolt.
I strip and fully clean the gun after every event, I replace all the superlube in the rifle. As after a big op in a sandbox, the gun is nicely coated with black grit. And yea, clean the hell out of that inner barrel/hopup.
I cannot stress how important it is to make sure the brass inner chamber and buffer tube coil are lubed... like, super lubed a lot... this is directly where the steel bolt contacts. These areas see the most wear besides the small internals around the firing pin.
If you don't lube these areas, after a day or two of just using sili oil, you will be looking at a replacement part.
On that note, the forward assist for some people seems to pop out, the good news is, for 8 dollars US, you can just replace it with a real one!
