Magpul Hunter American stock

[Frontier Gear]

.........my Howa action arrives tomorrow

The Howa and the CZ are both known for trouble free feeding with the Grendel and both use a proprietary mag. The Howa is a center feed and I "think" that the CZ is as well. The Grendel can just be a bugger to get to feed reliably at times.

I've had two RAPs in 6.5 Grendel and both of them were really picky about the position of the mag. The bottom of the mag "rocks" back and forth in the stock. If the bottom of the mag was pushed forward at all (the back of the mag moved down in the action and the tip of the bullets pointing up more), it didn't want to feed. If it was too far forward, the bolt would actually skip over the top of the round completely.

Also, the AR mags are much stiffer and there is a lot more drag between the shell case and the feed lip than there is on a Howa mag. Mine were leaving big ol' scratches on my brass. In the end I gave up, sold them both and purchased another Howa. I hope that you can figure yours out though and post the fix for everyone else.
