For: Bravo 10.5" RIS Hand GuardProduct Information:
This product does not come with instructions nor have I found any tutorials online so I will sum up how this installs. First you must uninstall the stock hand guards and any sites that are in the way. Then remove the stock barrel nut and replace with the barrel nut seen in the picture. Now there are 4 rings that come with it and these help to get the proper spacing of the barrel nut. You may not even need them or you may need one or more (I didn't need any on a Classic Army M15). There is a piece that attaches just below the barrel nut but above the front hinge. Then the whole rail is slid on over the barrel. If you are having issues getting the rails to align or everything is wobbly after complete installation, try removing or adding one of the rings under the barrel nut. After you get a good fit, tighten the screws and torque them down as tight as you can possibly get them. You are attaching the rail system to the barrel nut. Be sure the top rail of your rifle is straight with the top rail of your RIS hand guard. Your rail shouldn't have any wobble when complete.
The craftsmanship is good and the details are high quality
It is super light
Lots and lots of rails
It is a major pain to install (prepare for a few hours and lots of cursing)
I would not suggest an inpatient person try to install this RIS hand guard
Not a fan of the way it attaches to the rifle - could be a better design (example: Daniel Defense Rails)
