I am now just "overweight" now

Why you want rail for Kalashnikov? Is not good enough as procured from Izhevsk Mechanical Works? You think needs improvement? Then maybe you find job with army of Russia! You have drinks with Mikhail Kalashnikov, trade story of many weapons designed and details of school for engineering!

Or maybe you not do this. Probably is because you never design weapon in whole life. You look at fine Russian rifle, think it need crazy shit stick on all sides of weapon. You have disease of American capitalist, change thing that is fine for no reason except to look different from comrade. You put cheap flashlight of Chinese slave factory on one side, you put bad scope of American middle west on other side, you put front pistol grip on bottom so you are like American movie guy John Rambo. Maybe you put s*x dildo on top to frick yourself in butthole for making shameful travesty of rifle of Mikhail Kalashnikov, no?

Rifle is fine. You frick it, it only get heavy and you still no hit largest side of barn. Go to firing range, practice with many magazine of cartridge. Then you not need dumb shit put on side of rifle.
