Great for ruger ar-556 - UTG Pro AR15 15in Carbine Length SuperSlim Drop-in Handguard

This is a very unique looking rail and I can appreciate that but I do wish I had went with the mlok version instead. Utg does send you a few 1913 rail sections that screw into this handguard but they are proprietary and the mounting screws are very tiny. If I had gone with the other version I'd have a lot more robust mounting options. I also had some trouble getting this handguard installed over my bayonet lug. This is not a handguard that you would want to install and remove multiple times due to the tiny screws it comes with. Find the gun you want to put it on, use loctite or Vibratite and leave it
