Where should I send my Keymod Mod 2 upper to have the rail swapped?
I have a Keymod Mod 2 upper and the URX4 Mlok rail.
I want to do it myself, but I don't have the gas block wrench.
I've emailed Operationparts a few times and got zilch from them. I have also emailed an inside guy and haven't had any luck with him.
Thanks for any suggestions.
