My grendel had poor reliability until I worked some bugs out
I replaced the extractor/spring/rubber donut.
Installed an seekins adjustable gas block....tuned it.
and noticed, when shooting side by side with my old 6.8SPC, hitting the bolt release, the bolt running home felt much less...smooth...kinda chunky as it fed.
I looked at my CPD mags, and notice the mouth of the brass was banging into the front top of the magazines.
I carefully filed a ramp into the front of my mags.

This rifle also runs reliably with my ancient CProducts 6.8SPC mags.
Since tuning the extraction, and mags, I've been running it hard, 20 round mag dumps with crappy wolf ammo.
it's been running great, 200 rnds, so far, not one malfunction, and solid hits on 400 yard steel, all with dirty crappy wolf.

I've filed and tested all my grendel mags
I had a newer CPD that swelled & split, and Brownells offered to exchange with a 17 E-lander. ( been waiting weeks )
My current favorite is the 17 E-lander,....or honestly...my ancient 6.8 25 rounders, loaded with 20 6.5G's

"The rifle itself has no moral stature, since it has no will of its own. Naturally, it may be used by evil men for evil purposes, but there are more good men than evil, and while the latter cannot be persuaded to the path of righteousness by propaganda, they can certainly be corrected by good men with rifles."
