No they aren't just watch a youtube video and have at it. The problem with those mounts is they are beholden to three points of contact and if your receiver is out of spec even slightly then the mount will be wonky no matter what you do.
I used a basset low picatinny with a dab of ceramic threadlocker to avoid all that noise. Worked great and never jammed.

They arent difficult to install but you first need to take a series of measurements to confirm/deny your receiver is in spec or not, as you have seen in Tony's vids. If you have a Springfield M1A receiver, chances are fair that it is not. If that's the case, you'll need to determine to what extent, record the measurements then send your mount off to Sadlak to be machined so it will fit/mate correctly to your receiver. That's the most difficult part of the entire process. Rest is easy.
