One of the best ar handguard / rails on the market! - Troy SOCC 5.56mm Low Profile BattleRail

I've been using these types of Troy Rails for over 15 years going back to the first ones produced. They are so easy to install using the standard AR barrel nut so no special tools required. The lockup system also allows for a seamless integration with the upper with no tension tabs on the bottom of the rail that eats into your hand like so many others. Properly installed these rails are rock solid and are extremely comfortable as well as being light weight. Once you've used one of these rails your going to have a hard time using anything else. Excellent product from TROY!
