how easy is it to assemble the lasermax guiderod beam on the p226?
I don't think I can help you. My Viridian Green Laser I installed on my Walther p22 is an external laser that slid onto the accessory rails under the barrel.
The laser you are asking about is, I believe, internal.
I would check the Sig Sauer web site, web forums and/or ask your local gun shop, they should be able to help you.
