Original bolt that came with the barrel and the replacements I've gotten are all type 2. It shoots lights out and from the forum here it runs a little fast cause I shouldn't be seeing some of the speeds I get with 18" barrel and suppressor, but brass shows no pressure signs.
You could try adding some tungsten weights to the rifle buffer and make it heavier.
If it is unlocking early going heavier will help stop that.
I would stay with the JP spring as it's a tad stronger then the basic rifle spring.
If that doesn't work let me know I have a spare jp scs you can try and see how it acts with it installed.
You could trying to turn down the gas as well.
