Re: RRA operator stock
When looking at the butt plate you will see 2 screws, one holds the sling attachment on and the other holds the stock to the lower receiver extension tube. Remove the screw and slide the stock off. The extension is screwed into the lower receiver, it can be removed with an adjustable wrench, it has standard right hand threads, When you start to remove the "tube" it will release the buffer detent and spring. The rest is self explanatory. Also the rear takedown pin detent is loose when you remove the stock.
