ISTR it is a bit shorter the the archangel stock. Mine is pinned (there is a great how-to on CGN) so it no longer folds. With a 10" charger bbl and the stock collapsed, its still >26".
I have not had any issue with quality, but others have had problems with the sliding mechanism breaking. If you search "G36C" here you should find a ton of info for your build. Post pics!
