Yes. I lapped the reciver face and did a compression fit bedding with steel shim stock that you can get in a roll.
Bedded the gas tube into the gas block, blocked the gas tube roll pin up so gas couldn't leak through it and hand cycled the action while soaking wet bout 300 times.
Do this to all my ar grendels.
