Magpul BUIS airsoft vs Real

[krw]

I just bought a Armalite AR-10 that came with a set of MagPul BUIS. How do I tell if they are the good ones or the Airsoft version? This is the first set I have had so don't know the difference. Thanks! krw

The Airsoft front sight has an allen set screw and is just threaded in. Doesn't need a sight tool to adjust.

Don't know how to explain the back sight. except is not total peace of shit.

I have a set incase my aimpoint T1 ever took a shit. (So... I have never used them ) But I have checked them a few time and have never lost zero in two years. With that being said I don't know if I would trust them full time if it was more than target/hunting.
