Go slow - real slow. Like a quarter turn of cutting then back it out and repeat. When you snap a tap use a nail punch and hammer to push out the tap and/or bust it apart. Drill the hole clean an try again.I found a couple posts about the taps breaking while trying to install the guide. WTF do you do if you actually get the broken tap out? Re-tap it with larger tap?
Wondering if a buying a Wasr-10 w/o needed mods would be simpler.

I busted two taps. Remember to add a drop of red Loctite.
