Any here ever tried gluing their barrel extension into the receiver with Loctite?
Why would someone want to do that?
I will use locktite on the barrel extension on a target/long range rifle. I will not do it with a standard rifle. I like to take my hard use rifles apart once in a while to clean them up thoroughly so I won't use locktite. If you get a quality receiver that you have to heat up to get the barrel in then locktite may not be necessary.
I do it on precision builds
Ummmm, no. A properly fitted and lapped barrel extension fit in the receiver would be more important for accuracy than "gluing" them together. The loctite will most likely break down under the heat of firing anyway, so why bother?
You're essentially bedding the barrel to the receiver. Here is a good thread on the topic - https://www.m4carbine.net/showthread...rease-accuracy
I just read through that thread, and it didn't exactly illuminate anything in regards to the efficacy of using loctite.
I tend to agree with this notion.....but I guess the phrase "how can it hurt" comes into play here. Other than difficulty removing your barrel from your upper, what are the drawbacks?
One note on this, after removing my White Oak barrel from a WOA factory upper, I noticed that they used red loctite and it was a PIA to remove. I'm rebuilding my precision upper using a billet upper, but I'm not going to use loctite (only anti-sieze grease) when assembling everything back together.
Drawback I can think of is precisely what you stated: not being able to separate the barrel from the upper if/when it is desired to do so. Deep cleaning? Barrel replacement?
Not to mention the unknowns of having a chemical inside your upper which isn't designed for the heat loads its experiencing there.
What makes you think you wouldn't be able to take them apart?
Applying a heat gun to the parts will make them easily removable. There is no permanent loctite.
That being said, red loctite isn't what I would use, but rather the sleeve retaining versions which are typically green. I think its 607. Its not going to make a 3 MOA gun a 1/2 MOA one. But, you might make your 3/4 MOA rifle more consistent across different tempratures or take that 3/4 MOA and maybe make it a 5/8 MOA.
If its not a rifle I'm going to shoot for groups, I wouldn't bother.
