Hello all, I'll start by saying this is my second build AR, and I've done a compensator install on my first AR. But for the life of me I can't remember if I used any kind of adhesive. I sold the first AR a while back. This one has a BCM barrel. I installed an FSC 556 on it and timed it properly an everything, but wondered if I should have use blue loctite, red loctitie, rocksett, etc. It's a 16 inch barrel so I don't want to pin it. Is proper torque enough or do you use thread adhesives? Thanks in advance. I also posted this in the "build it yourself" but haven't received any feedback. |
| used to drag race in my earlier years.. first time I saw the distortion in symmetry in a cylinder bore caused by torqueing the head bolts (first time using a torque plate to hone cylinders) made an impression as to the damage incurred by applying torque to symmetrical objects... I index with shims or nothing requiring more torque than a spark plug gasket... red Loctite comes loose with a little heat... |

The thicker washers used on today's hider or brake should be tightened till it indexes correctly. They do make shim kits for units that do not index with stock washer. |
| A crush washer is all that is usually used. I have seen several videos where the muzzle brake flew off during full auto though. Semi auto allows us to keep watch on the muzzle but it is never guaranteed something will not come loose. I say do what you need to be sure. |

A crush washer is all you need. As a general rule, keep loctite away from an AR, unless you're using blue on optics mounts, or some sort of clamp or set screw gas block. IMHO don't use this crap on anything except adjustable trigger screws and only the Blue stuff. |
