Great handguard, tough installation - Precision Reflex AR-15/M16 Round Free Float Carbon Fiber Extended Forearm

If you're buying this handguard, you're buying it for a specific purpose most likely. The handguard is great and really solid. However, it doesn't come with the wrench to tighten the handguard down, so make sure you order that. Also, the barrel nut may not align with the usual torque so a spare might come in handy. Mine was a pain to install and get gas tube alignment to the point I had to torque it to 75 ft-lbs, 10 more than spec and only 10 fewer than the upper receiver TDP spec.
