Contra-staking, anti-staking, or removal of the staked castle nut...

[dorchester]

I need to remove the castle nut on my nice, properly staked LMT in order to instal an A-5 R.E. So, is this a big deal or just a turn of a wrench to accomplish? I have an action block and the multi tool/wrench in my toolbox. Go for it? Also, are all the parts considered re-useable for the re-installation of the new R.E.? Thanks.

indeed.. but what most of them wont tell you is that it's best to put the RE in the vise, rather than use a block and put all the torque against the receiver. pad it with something- i use squares of rawhide- and chuck it up so that it won't rotate, then use just enough force to hold it in place. you don't need to, nor want to, crush it.

also to protect the receiver extension, it helps to de-stake the stakes. the best way i've found is to use a dremel cutting wheel to actually grind out little spots in the end plate behind the stakes. makes it a hell of a lot easier and less likely to hurt anything.

dont peck at it- put your wrench on there and give it a manly thrust. the more you pull and tug and **** with it, the more you run the risk of slippage/cracking/stripping, etc.

It's pretty easy with the correct wrench. In the last 2 days I have broken 3 castle nuts loose and hardly broke a sweat.

My observation as well. I've had good results with the HammerHead tool. It engages all four slots on the nut and gives you good leverage.

well first you will need a plasma cutter, then a 5lb sledge hammer and probably a.... oh wait, no nevermind

:moil: I just throw the gun away. You can never break one loose if it's been staked.

Everyone on the internet knows this.

Is it wrong to use a mag block and vise?

OP here, Thanks for the helpful, humorous and polite tips. A "manly" thrust, indeed.

Next to a "bigger hammer" a "manly thrust" is the way to go.
