To a car wrench? I need to tighten down my castle nut on my stock, right now it is just tightened by hand, I got the buffer and buffer spring in, just need to tighten down the castle nut, is there any other household tool I can use?

It does not look like there is any other way so I assume I am going to need to buy the tool?

I'm sure someone will post another way but me I would just buy the tool. How about asking if someone in your HTF has one you can borrow?

I didn't buy the wrench, so as was recommended to me I used a punch (1/8" I believe) to "grab" the notch and tapped it with a hammer until I felt it was tight.  

The right way is to always use the right tool, but anyway...if you decide to try it be careful not to let the punch slip. I did it successfully on both the builds I completed this weekend. Good luck!

Hi!  new here and in no way an expert (working on building my first AR), but I just tightened mine as much as I could by hand...  Then taped up the end of a flat head screwdriver with a generous amount of electrical tape, held the tip of that taped up screwdriver in one of the notches and gave it two moderate whacks with a hammer.

Seems pretty solid...

You can use a strap wrench in some cases.  Or the other bubba methods suggested.

Obvious right answer is buy a CAR wrench.  You can get a good one for less than $10 and it's something you should keep with your gear anyway.

I thought most armorers wrenches had a fitment for the castle nut?

Screwdriver/punch to get it tight, then use a screwdriver to stake the end plate against your castle nut.
