Im going to order a 20" gov't profile A3 upper for my upcoming M16A4 build. I ordered a M5 RAS from Stokes on here, and i ordered a complete A2 buttstock assembly. Keep in mind i will purchase this all from www.model1sales.com Well to be completely honest with you, im going from a M4 to the M16A4 i need to get rid of the collapsable stock, not a problem. But how do i install the A2 correctly. The donor lower is a Bushmaster M4A3 patrolman. Just overall will what im going to buy, will it work on this, im new to the black rifle life, so anyhelp is appreciated. Thanks.

Installing the A2 stock is easier than removing the collapsible stock, very easy.  

Just screw the rifle extension on to the receiver, and make sure the buffer retaining pin is seated properly, put the rear takedown pin and spring in their proper place, put the stock spacer over the end of the rifle extension, slide the stock body on, and screw it all together.
