An A2 sight tower is a fixed front sight post assembly commonly used on AR-15 and M16 rifles. It serves as both the front sight and gas block, featuring an integrated sight post for elevation adjustments. The A2 sight tower works with AR-15 barrels (with appropriate diameter and taper pin holes), upper receivers, delta ring assemblies, handguards, and standard rear sights. It’s ideal for traditional military-style builds, providing reliable, durable iron sights and gas system functionality.
