In case you end up getting one, do not put Magpul MBUS on the railed gas block. Too much heat for the polymer sight. You would need to get the Magpul Pros, or some other metal sight.
I had a gun company rep say poly sites were fine, just don't shoot rapid fire. He suggested MFT sites that look like cheap garbage to me. I call MFT for fun and they agreed they were ok unless rapid fired. I bought some metal sites to be replaced by Magpul Pro's eventually. Until then, the ones I have will back up my Sparc AR red dots.
