Loctite and handguards

[kAnJii]

Hello all,

Is everyone using BLUE loctite when screwing down their handguard/handrail systems near the barrel nut? Or RED loctite or none at all or????

If your handguard needs locktite they're doing it wrong.

Some manufacturer's like KAC require loctite for installation of their rails, but if the rail manufacturer does not call for it do not use it.

Its not needed you will do more harm than good when you need to take it off.

Anti seize lubricant is preferable because it will allow you to tighten it a little more and will make it not as difficult to remove.

Used red loctite on some off-road lights years ago. Had to undo the bolt soon after installation. Messed it all up. Never sat right again.
I'd only use red on something I was confident I would NEVER have to undo.

I just use teflon tape on my screws. Screws will never loosen unless you want them to and easy enough to re-teflon. I know it sounds ghetto but it really works

All my KAC rails called for loctite and my Larue PredatAR had loctate on the rail to receiver screws, please enlighten us on why they are doing it wrong.

If they engineered it so poorly that they need to use loctite, then they're doing it wrong from the getgo.

What do you expect from a government contractor like KAC though. They could learn a thing or two from Geissele. . . you know, the people who get the contracts to replace the stock government crap.

I just put together an ALG defense rail and used blue loctite on the screws that hold the rail to the barrel nut.

If you ever use red loctite on anything, plan to use some heat to soften it up before trying to take the screws out.

go blue, red will work but you'll need a heat gun to remove items.

If Loctite, always blue. Red is permanent and a bi*tch to loosen.

Blue loctite is such a commonly used product, it is asinine to ascertain that poor engineering is associated with the use of loctite.

KAC URX rails require loctite because the barrel nut is aluminum. You cannot torque an aluminum barrel nut to a high enough value before it strips out, so you need to have the added strength from the loctite.

For a steel barrel nut, you are absolutely correct that if you are using loctite you are doing it wrong.

The Predatar uses loctite on the receiver screws because again, it is aluminum on aluminum. You cannot tighten the screws to a high enough torque value without stripping out the threads on the receiver, hence the use of loctite. I bet you that if the barrel nut is steel on the Larue, it is not loctited on.
