Congrats AK.

I have an AAC M4-1000 and love it. It shifts very little and is mostly repeatable. Not bad for a QD can.

I was checking the relief cut on my Douglas Barrel and it doesnt look deep enough. I bet the threads are landing and preventing shoulder contact.

I dont like shims on cans but, I really dont want to send the barrel back to Douglas.
