Great handguard with one issue - Precision Reflex AR-15/M16 Round Free Float Carbon Fiber Extended Forearm

this is great, its sturdy slick, give a slightly retro vibe without the clamshell handguard. the one issue is that it needs two special tools and doesn't come with them, a spanner wrench for the collar and the barrel nut wrench. the barrel nut looks to be a standard pattern but you really need the one they make with the longer posts.
