Help me before I give up on the Grendel altogether

We don't know anywhere near enough about your components and assembly methods to start diagnosing your FTFeed.

Is the bolt presenting over the base of the cartridges, or is it behind them when you see the malfunction?

What is the gas system length and barrel length of each barrel, and what are the gas port diameters?

How did you install the gas blocks?

So, I thought maybe I need to increase the reliability by running a VLTOR A5 stock system. So I installed it to replace the Carbine buffer. The FTFs are still happening.

Did you use the A5 buffer along with the A5 RET and spring?

It's interesting because in all my years of building these things, all of my builds run out of the gate, whether they be multiple samples of 16" MLGS, 20" RLGS, 18" MLGS, 22" RLGS, or 12" CLGS.

I do a lot of things to nip any potential malfunctions in the bud before the parts go into the guns though, learned over many years.

That Wolf 123gr SP ammo was the only ammo I had a malf with in my first 16" Grendel build.
