I must admit, you did a great job. When you shoot it tell me if it's sights in, I've heard people that have went this route has had trouble with the elevation. I wouldn't think so, but thats what Ive heard.
I've been looking for a factory gasblock sight for a few months now, no luck yet.
I have it on the ac556 in the pic (I wanted to make sure it was going to sight in). I have aquired all the clone parts I need, but haven’t bought the mini I am going to need to sbr yet. Been looking locally, as it seems like you get a better deal (both in price and in thrown in accessories and ammo).
