Sorry for the delay, it's been awhile.
The install of the rail is really simple, the most difficult part is getting the handguard off in the first place(simple, just stiff as hell).
Place the butt of the rifle on the floor(or any other solid surface) and pull the D ring downwards, once you get it to clear the guards tab just pull out the lower half. Find out which holes you're comfortable with and attach the rail then re-install the lower guard.
One thing though, the spots in which you place the nuts aren't really nut friendly per se, if you have a Dremel and a grinding wheel you're able to open the sides of the spots a bit for a better fit(just be careful not to go through the handguard).
Edit: The rail came with nuts and bolts for attaching.
2nd Edit: Here's a link to the rail I purchased.
