6.5 Grendel

[Critter Picker]

What type of magazine are you using? I've been told to use ARStoner mags, feeds slick as snot on a doorknob. Everybody told me that the Grendel is really finicky so I have the metal mags.

Using the Duramag (28) I think.

Tested each mag with single sbot to see if they functioned and locked back. Each worked fine. The tested with multiple rounds and found one that functioned less reliably.

Will pull the scope and test it on a shooter to make sure that is not issue.

Test different ammo.

If that fails, I think it is a barrel issue.

Good.
Perhaps just slightly low enough on pressure to not lock back.
Could still be a slight gas issue.
Could be slightly tight lug to battery...enough to drag a teeny bit.

Are you using an H buffer or standard carbine buffer and spring? This will make a difference on lock back and/or picking up the next round as well.

Either way...Accuracy shouldn't be as bad as you are seeing.

Not sure on the buffer. Using a lower from a Springfield Saint 16" I had. (New to ARs, shot my buddies Grendel a few weeks ago
and decided to order one).

Well cleaned the barrel today. It cleaned up pretty easy with BTE. I did notice it felt a little rough in spots. At least when the patch was wet. As I dried it out, they felt smoother. We shall see.
