I do not have the equipment to do handloads.
I did order a Spikes T2 buffer, will have to see if that helps
What's your gas port diameter?
You might need the port opened since you have 18" RLGS.
Most 18" Grendels are MLGS, which is gassed pretty hard, but some have a more ideal Intermediate Length Gas System.
Precision Firearms introduced ILGS many years ago, and I think Odin Works uses it as well.
If your port is too small, with that reduced plug dwell time, it can cause short-stroking malfunctions.
Does the bolt ride over the base of the next cartridge when you see the malfunctions?
