The Chart for ar 10?

[SHIVAN]

Well if 7.62 AR is a broad term, for which you have AR-10 and SR-25 pattern rifles, then what would be the full sub-category break out?

It would probably be safer all around to refer to them as what they are:

LR308, OBR, SR-25, MWS, AR-10, etc. Just like you do with an M&P versus a Glock.

I think the crux of this is that Todd's saying that ONE chart doesn't work when something like a Noveske rifle is not interchangeable in parts with an SR-25, thus it creates a disparity in the list.

Nomenclature aside it's certainly a tough thing to categorize.
