As said above there are a lot of DBM's on the market right now with more to come i'm sure. Take a solid look at what you are going to do with the rifle, my hang up was that eyesore of a tab sticking off the bottom of the trigger guard as you will see in a great many of DBM's, functional? yes. Ugly as hell? yes. Possibility of inadvertently ejecting your mag when the tab catches on something? yep.
If your going to be beating this thing in the field, I prefer something more refined like the Seekins or APA. Much harder to "accidently" spit your mag out at the wrong time. I have an HS Precision system on my 6-284, nearly flush fit with the stock & the release is protected.
When inserted, you can't hardly even see it & still retains 3rnds.
