I have a BCM EAG rifle. I am going to remove my front sight and need a new gas block. I have never bought a after market gas block so I am looking for input on the best option for a gas block. I need something that is totally secure (I know the claps can move on you)and reliable, this rifle is my patrol rifle. Low profile is preferred to avoid anything can snag. Hope you guys have some input for me, I look forward to reading what people have to say.
