I'm installing a BCM low profile gas block on a BCM barrel that has a dimple for one of the set screws.

 

Is it worth putting blue loctite on the screws or should I just torque them down and trust the dimple? 

 

I've watched a few YouTube videos on gas block installation and no one seems to mention using loctite.

 

I didn't loctite mine, but honestly, i would use red.  The probability of ever having to remove is slim to none in NJ... and it shouldn't ever work its way loose. I dont see a reason not to.

Use blue Loctite. It's good enough and will allow you to remove the screws, and therefore gas block,  if you ever change your mind down the road..... Not that you'd ever change your mind about your AR setup, right?

Loctite not necessary, just tighten them up and go.  Heat of the barrel radiating would probably break down blue Loctite anyway.

It makes it hard to when it requires cutting off a muzzle break...

Thanks for all of the replies - I'm going to skip the loctite for now and just make sure that the rear screw is properly set in the dimple and just make sure that both are securely torqued.
