AERO PRECISION ATLAS S-ONE M4E1 THREADED ASSEMBLED UPPER

I could probably devote an entire website to Aero Precision’s various AR-15 combos, specials and one of a kinds. Anyhow, this time Aero Precision is combining their fantastic threaded M4E1 AR-15 upper receiver with their Atlas S-One handguard. The AERO PRECISION ATLAS S-ONE M4E1 AR-5 THREADED ASSEMBLED UPPER system is designed to match seamlessly creating an upper so sleek it rivals the rigidity and appearance of a monolithic upper. At $199 the system comes in cheaper than many quality handguards alone.
