The wrench??

[RoscoeP]

I have a CZ858 that I will be putting a AR style stock with buffer tube on at Xmas(don't have yet) I have the adapter. My son told me last night that I will need some special tool to tighten a nut that goes over the buffer tube.
The stock is from a Bushmaster, where can I get this tool or is there something I could use? Any help appreciated. Cheers Roscoe

This is the wrench used for the nut on the stock. I'm sure most shops that carry AR parts will have these in stock.

Yep, the wrench is a spanner type tool, nothing too special. I purchased an AR multi tool which has it, but I've seen guys gently use a hammer and drift to loosen/tighten the nut as well.

thats what i do, never needed the special tool to do the job.

I ordered the TAPCO wrench from ebay and it doesn't fit the jam nut very well. I had to file off some to make it fit.

Where did you buy the multi tool from?

I think mine came from Brownells, but any shop that carries any AR stuff should have one.

PS:

If you happen to be in the YYC area shoot me a PM if you want to use mine.

wrench

If you live in the Vancouver area you can borrow mine and do the work here or take the wrench home and do it there.
