AR-15 Castle Nut Staking

What do castle nut stakes, barrel dimples, anti rotation tabs/pins, and barrel nut through bolts all have in common? They are a physical barrier that prevents a part from moving in an assembly that is subject to a lot of nasty vibrations and heat that tend to make things move.
Friction alone should never be the only means of retention and if you bet on it, eventually you will lose. Putting a piece of metal in the way is a much more secure method of keeping a part from shifting or coming loose.
Friction might be the latch that keeps the door closed but stakes, dimples, pins, and bolts are the locks that keep the latch from opening when it shouldn't.
Staking isn't very difficult and can be done with even a simple punch, hammer, and soft table to do it.

Dang, that device you have to capture the buffer tube and prevent the lower from rotating is genius!

[@danajm]

Lets talk about that tool... Want one...

[@TrajectoryArms]

Very soon. The production designl has been finalized so they will be ready shortly

[@TheStevenbryant19]

So where can someone get that tool you're using with the geissele block to hold the lower?

[@GTWGamer]

Great video, I was wondering what's your typical turn around time?

[@TrajectoryArms]

It really depends on the time of year and our workload but you can always email [e-mail] for updates and to discuss your build.

Ive been battling RE keeping it timed while torquing castle nut. Would love to know the name of the tool and if that tool is finally available to go under reaction block?

[@anthonychirillo539]

Love the videos, man. Do you have the make/model of the tool you use to lock in the receiver to the vise? Not the reaction block, but the tool below it.

[@TrajectoryArms]

We make it. Held up on production for now but hopefully we will have them out soon

[@smith240sx2]

Is this the Wilton 550p or 650p? thanks!

[@TrajectoryArms]

It's a 550p

[@smith240sx2]

Wow, seems like I’ll need the 450p for my small shop. Thank you!

[@TrajectoryArms]

I started with a 4" Irwin and did a LOT of work with it for a couple years. The wiltons are a nice upgrade though.

[@smith240sx2]

@@TrajectoryArms that’s great to hear! I just don’t have the room for a 5.5” I’ll get the 4.5” and use till I put grow it. Thanks for responding, I have really been inspired by your quality of work.

Will that tool work with the kley zion buffer tube block?

[@TrajectoryArms]

Not likely, the dimensions dont quite match. We are working on some for use with folding adapters and the Kley-Zions as well.
