NOTE :  The Grunt rail is designed to fit tight around upper receiver screw place.  Certain batch of DR200 is having bigger diameter in that area, it prevent the Grunt rail installed properly.  We haven't heard this issue on hundreds of K2(in South Korea ) and K2 pattern rifle in USA. But a couple of cases of DR200 are reported.   


We recommend to file or machine outside diameter of screw place to use the Grunt rail if you are having issue. If anyone who want to know the dimensions of rail to machine your receiver, please contact us.
