Either are GREAT Lowers with the ambi-release built in. One Great thing about the Phase 5 is the Ambi Bolt Latch open feature. Both the Seekins and Mega are only for releasing the bolt but when you use it to lock the bolt back, open, that's the ticket. I use it all the time when charging a round or just want my bolt back, none of this dis-contorted pull it back and trying to manipulate the bolt catch. Easy one step with the right hand on the grip and charge it with your free left hand....
