I'm about to put together my first couple of AK's. I was wondering if any one has a tool I could borrow or use to complete this task.

I'm really trying to avoid spending $250, and I don't know much about riveting things to make my own tool.

Alternatively, if you have a tool or tools you're looking to sell, I'd be interested in those.

If you built an AR, which you are now selling, list the BRAND NAME of each part, not the fact that said part is 'mil-spec'
