Is there a need to stake a sling mount?

Magpul ASAP sling mount. Should I stake it to the castle nut?

[sammage]

If you want to keep the castle nut from loosening, yes.

The ultimate answer is definitely yes. I personally fired mine a couple times after installing such an endplate to ensure that I liked it first. Not that staking is permanent, just a 'measure twice, cut once' kind of approach.

When in doubt, deform metal to ensure proper function. This is before I knew what "staking" was.

You learn something new everyday.

For the ASAP or any other sling mount that replaces the end plate definitely yes, stake it

[mkmckinley]

The question is why wouldn't you stake it. It's ridiculously easy and the tools, if you don't already have them, are cheap. You can get away with a hammer and a center punch or better yet get a spring loaded center punch. It's like a 2 minute job.

And staking isn't permanent. You can torque the nut off. It just keeps the nut from loosening on its own.

[Magic_Salad0892]

As it's been said before. Yes. Stake it.

OK, the sling mount plate is higher than the castle nut. They aren't flush. How do I stake 'em!?!?

[9114]

I would its just couple of bangs and youre all good

[GTifosi]

They don't neccisarily need to be flush or level with each other.
You just have to be able to displace material from the edge of the plate into *one of the notches in the nut.

*One because that's usually all you can get with the ASAP before the wedges on the sides get in the road. Still, one beats none by 100%.

Oddly enough, or not, the instructions that come with the ASAP make no mention what so ever to staking. Just tighten it down and have a nice day.

When I put one on my old rifle I hit it with a spring loaded punch about 20 times to get the metal into the nut.it held great but was a bear to deform enough
