Well I just ordered the RAM and striker block. Hopefully it will be here in a few days. Will try to install them myself, hopefully it all goes well.
If you're remotely mechanical, is pretty easy. You'll need a punch for the pins, a non-marring punch and an allen wrench for the rear sight. Here are videos that I used:

Be careful removing the rear sight. The spring for the striker block is under it and can go flying.
