T97 Piston and Gas Regulator too tight?

[Duke878]

Fired about 150 rounds a few weeks ago. Oiled up the moving parts to soak before cleaning. As per, I didnt not oil any gas affected parts (IE gas regulator and piston assembly). Of course theres carbon in the piston and took a good few wacks with a hammer to take off the gas regulator and piston... is it too tight or is that normal? any way to prevent this for next time?

Thanks!

Carbon deposits do tighten things up a touch.
A dirty gas regulator will do as you have found.
Leaving it dirty for an extended period after firing is a no-no.
Corrosion and siezing can even happen.
Beg your deity for forgiveness immediately and be prepared for internet ridicule to commence.


Oil and clean as you do the rest of the parts, the piston and gas regulator too.
Only dry off the gas piston and regulator head before putting together.

The cup nature of the gas regulator will guarantee that there will always be the smallest amount of carbon in it that you just can't get out.
Do the best you can.
A bit of oil on pot scrubber cut into a tiny piece and twirled around on the end of a tool will do the job dandy.
Getting the majority out and this kind of oil and cleaning will be good enough.

The first round will always 'blow' it into working.

Yes, I found that too. I pried the regulator out and pushed the piston out from back.

That's normal. Just tap on the piston to disassemble as needed.

Mine are definitely tight, but not hammer tight. I usually lightly pry with a flat screw driver.
