A. Who the heck is HA?
B. Get some factory ammo.
c. You have cobbled together some dubious components. It's not a mystery why you are having problems. My first is something gas related. Your post was a little hard to follow.

I picked up 20 new Okay Sure-Feeds a few months back. With 5.56 and .223 I've seen no problems whatsoever. No experience with other calibers on those mags. Have you tried PMags? What are the details on your rifle and ammo?

Just got back from the range...just now. Got it running. I tinkered with it all weekend. Turns out my main problem was that the SLR Sentry 7 gas block was bound up and not adjusting down far enough. I did not notice the problem while adjusting the screw with the handguard on. The bolt was outrunning the mag spring. This morning I got it to run suppressed and unsuppressed and lock back both ways on empty mags.

It ran like a champ today. No mag issues either with the Okay's. I did also try out one of the 300 blk mags that BCM sells. I ran good too.
Thanks folks.
