I'm just glad to see you have the bipod in the correct spot. For your over-gassed PSL, try sending it to Jim Fuller if you don't mind spending $450. He does really good work.Rifle Dynamics 07 FFL/SOT - Las Vegas | GSR
Not to concerned about it really. I know a guy that machines adjustable gas blocks anyways so if I really get an itch I'll just go that route.
If anything I am considering a UK59 heavy barrel and doing a total tear down on it so it would be moot at this point.
