[darks]

[WDE91]

yes
any AR15 lower will work

finding magazines that work is another story I hear with that cal

[evidens83]

YES.

[darks]

so what kind of mag should i use for it?

While any lower WILL work.. some will fit better (less wobble) than others. My BCM upper had a lot of movement on a mega lower (zombie). I swapped to a Noveske lower and it was much tighter (A JD lower most likely would have yielded the same result).

Now I test a lower to the upper to get an idea of fitment before I buy mismatched brands.

And yea, I know the wobble doesn't really hurt anything, just don't like it.
