Hi there Bob,
Just wondering where you tracked the Apex parts down at? Looking to do the same upgrade...
Thanks for the help!
Cheers
Sean
I ordered mine through Brownells IIRC. The kit is an easy install and well worth the money. All you need are roll pin punches. Just be careful when you replace the sear and sear spring. You don't want to lose the little ball bearing. I also found holding my tongue against my right cheek helped when re-installing the rear sight after replacing the USB.
Take Care
