The only problem with that is LOP preferences.
I removed the same odd ball setup from my BM, replaced with a 6pos RE from BCM along with a H buffer and new spring. The stock is pinned one notch from fully collapsed in order to be able to access the sling mount on the end plate. This is a much shorter setup than an A2... Some people (me included) are not tall enough to be comfortable with an A2 length stock. It's not the greatest option, but its an option.
