Front sling swivel m16a1 style

[wtheesfeld]

Quick question...

I want to install a bottom sling swivel on my colt m4, I have a swivel and rivet style pin from an m16a1.

Do I need to do anything special with this pin? Do I need some mystical tool? I haven't come across this before!

Thanks

Just in case anyone searches:

Use a small ball bearing or bb to flare the ends, then a large flat punch to flatten them. Very easy.
