Here are mine S & W MP 15-22 and MP 9 mm para
Due Dutch regulations the stock has to be fixed it's not allowed to move, can not see why I think has to do with hiding under a coat or something but that's the regulation.
Use a cheap but does the magnifier and a dot from GSG still looking for a new one but like everyone do not want to spend more on a dot then the riffle costs (Im still Dutch).
On my last visit to the states and bought a Surefire 6P CAA mount
Also attached a cheap foregrip which also do the trick.
Still had some lying arround railprotectors fit well but do not want to look for so long the Magpull Rail Panel will not cost me a fortune over here.
