So I traded a Ruger 10/22 for this mak90 about 8 months ago. It was NIB unfired, very nice, but I absolutely hated that thumbhole stock. Just ugly as sin to me. Anyway, I replaced the rear sight with a Mojo peep, the front post sight with a circle with crosshairs, put on a red Timbersmith stock set, and a 75 round drum mag. All I have left is the flash suppressor, it was supposed to arrive yesterday, but hoping it will show up today. The stock set was a real pain in the *** to install! Had to do an awful lot of sanding to get it to fit right. Came out pretty though.
