They are very well built, however I had an issue with mine, Armtac dealt with the issue very promptly and professionally, Chris is a stand up guy to deal with and I have NO problems dealing with him again!
The issue I encountered on my rail was the pict.rail screws were of the wrong pitch if you could believe it... My understanding is that if Novas made in the USA use a different thread pitch to those that are from Italy (the whole metric vs. standard TPI grading system), when the stock screws and the SideArmour ones are thrown on a thread pitch gauge the matches were off on mine, Chris mentioned that this was the first shipment outside the USA of them, so it couldve been a simple error on their part (Why cant we all just get along when it comes to threading!?!

) ... Anywho due to the screws not seating properly my rail was slightly canted

definitely noticeable with an optic on, however
NOT an issue Chris refunded the rail in an extremely timely manner and everythings golden!
Sorry to steal your pic posting thunder OP...
Good on SideArmour for doing SOMETHING for the Nova as its a very smooth operating shotgun to say the least
