Help on BCG

I am getting toward the end of putting my mid-length together. I have a BCM middy over a RRA right now. The BCM has a shaved FSB and a 13" Troy Battlerail Alpha. Troy flip-up battle sights and a Gunfighter Gen4 are now on board.

I am in a quandary over the BCG. Am I over-thinking this? It is going to be a duty rifle so reliability is paramount.

A BCM? An LMT? A Zero Fail? A Spikes Zero? Helpppppp…

Make it easy on yourself & ckik the orange search link!

If you have a BCM upper and charging handle why not just get a BCM BCG?
Im pretty sure no one would have an issue taking any top quality BCG and putting it in that rifle.

Can’t go wrong with a LMT, BCM, or Colt BCG.

BCM ordered and on the way!!

As other’s have said, if the other parts are BCM, might as well get a BCM BCG.
