I am looking to build a 6GT or 6 Dasher on a Gen 2 Ultimatum Deadline 3 lug action. I am a huge fan of AW mags from using them on the CDG. What is everyone's experience using these on a 3 lug action? For context, I'll be using a JP APAC for my chassis and was told that both the chassis and action will accommodate AW style mags.
 
Is the Ultimatum Deadline cut for AW mags? I didn't see it on their website, may have overlooked it

I built my wife a 6 BR on a Aero Solus action with the gray ops mags and it's been great so far, no issues.

Yes it is. I'm running AW's with it, though they've been a pain in my ass to tune. They seem to run alright now, but they were rough to set up.

My experience with AW mags is usually tuning the mag catch length until the mag is fully seated against the bottom of the action. If its cut for AW correctly that's about all you need to do. The Grey ops mag, as you know, can adjust the catch itself (same difference).

OP If you try and "tune" the gray ops mag feed lips you might have a bad day. Being milled aluminum and all..

Gotcha! according to the owner of IBI who makes the ultimatum deadline actions, he says it's cut for AW, JP said they'll tailor the mag catch for the action. So I thought i'd give the Gray Ops mags a go and if it's a no go, then i'll swap to MDT AICS mags
