Blue locktight or red on umarex hammer shroud?

Only use blue or green. Always unless your planning on a blow torch to remove it.

I normally never use red lock tight on anything unless you need to lock down a bolt inside a briggs and stratton motor.

Appreciate your comment but red was used because we wanted to make sure it did not come loose . If people want to use blue that’s fine . If I said blue and it came loose imagine the comments . You can heat up red . With the Hammer I figured I would use red . I have paid the price with blue Loctite on a big bore . Thank you for the advice , I appreciate it . 

Wow , Thank you . That means a lot to me . 

I used red on a moderator once. That was a bad decision... By the time I got the moderator back off it was pretty much wrecked.

Bad advice.. Green loctite 648 is high strenght used on purposes that are never meant to open never use it.

There are multiple green loctites.... for example, 648 and 680 are retaining compounds designed for slip fit cylindrical connections, for example great for installing permanent barrel sleeves and thimbles. I frequently use 680 for these purposes. Green threadlocker such as 620  (correction 290, Thx Doug. ) is a medium strength wicking/penetrating thread locker for use on already installed threaded fasteners,....

In some cases there's more to Loctite specs than simply the color. Different numbers for different specs/applications.

Some folks routinely and successfully use loctite outside of the manufacturers intended purposes For example, I frequently use 518 as a sort of bandaid when dealing with less than ideal sealing surfaces....If you have a leaky barrel due to a loose fitting breech, lather it up with 518, it will likely seal.

Yep thats exactly why people who recomend some glue from loctite should say product number instead of color. There is unbreakable glues atleast as two colors green and red and if some poor fellow uses 648 for aluminium finethreaded shroud its prettymuch ruined or permanently "welded" atleast since its even really heat resistant.

Need to get your numbers right. 620, 648, and 680 are for retaining. 290 is the wicking green for bolts. 

If you use 243(blue) correctly it will hold just fine. 

I would not use red.
