    Staking all the way. Why bother with Loctite? It's just a pain in the ass. A good staking job offers superior durability and at the same time, it's just as easy or easier to remove.

    I think I've seen an SR-15 with Loctite on the castle nut, however. Makes you wonder what the guys at KAC were/are smoking.

    I have no problem with Loctite myself and use it in many applications. Having said that, how hard is it to buy and use an automatic center punch?

    It's 5 bucks, a retarded rainbow monkey can use it properly, and it gives peace of mind.

    When swapped out the factory plate for a single point sling mount, I just tightened the castle nut down and didn't use loctite or anything. I have put about 1200 rounds through it since then and it has held up really well. I did mark it so I know if it is starting to slip, but I do that with every peice of gear that can rotate. I have done this on 3 rifles and have never had an issue but if you don't plan on ever changing it out, staking it would be good.

    It's possible that a castle nut can stay in place with nothing... not worth the risk to me...

    And Staking isn't permanently attaching or commiting. You can break and restake any time you want. That's why I put light stakes. You don't need as much as a automatic centerpunch gives you.

    That was simply for those too stupid/lazy to use a hammer and punch/screwdriver.

    Maybe it would be worth moving to $10 for an adjustable model.

    Centerpunch works fine.... don't get me wrong... It's just that you can get away with a light staking. You're only stopping the part from vibrating loose.

Then we would be arguing whether two drops was better than one, whether purple, red or blue was best. Then some lunatic would come along and propose staking, causing a general uproar.
    This is hilarious because it's plausibly true.

    Any properly torqued fastener should stay in place with no other additions or changes. Notice the word should again.

    There are a million and one instances where things just don't work like they "should" for whatever reason. People need to think of staking as functional insurance for their rifle. It's there to cover all the variables that you can't account for, and make sure that your rifle works when you need and want it to.

    Think of it this way, can you drive your car around without insurance? Yeah. Is it a good idea? Nope.

    In the same line, can you fire your rifle without staking. Sure enough. Is it a good idea? Again, not in the least.

    An unstaked unLoctited castle nut will work loose. This is true of almost all ordinary screws and bolts subjected to significant vibration. This is why you find virtually all fasteners on a car or truck have some method of self locking. It may be tooth like serrations under the head, a nut that has been squished to bind the screw, a screw with a triangular cross section, Loctite, et cetera, et cetera. I encourage you to continue with your unlocked castle nut and let us know if, when it comes loose. The one I tried lasted about a thousand rounds, longer than I expected.
