Takes Glock mags, comes with 33rnd mag. Has 1913 rail for stock or brace. I put the brace on it and it folds and operates folded as well. Barrel is 6" and is threaded (1/2 28) suppressor ready. Sights are flip up. Gun has sling mounting hardware ready for a sling. There's plenty of rail space on all sides of barrel for forward grip , lights, etc. The charging handle is on left side towards the top and charges kind of like mp5.. Actually it's reversible and non reciprocating.(T. his gun shoots straight and is a breeze to fire. It's a very well thought out firearm and I will get another for sure. Financial issues force me to sell it . Call/text DanREDACTED
