Aero Precision M4E1-T Complete Upper 16" - 223 Wylde

This complete upper includes Aero Precision's new ATLAS R-ONE Handguard on their billet-style threaded M4E1 upper topped off with a 1/8" twist 416R stainless steel barrel chambered in .223 Wylde designed to wring the most accuracy while maintaining full capability with both .223 Remington and 5.56 NATO ammunition.

R-ONE handguards are designed with size and weight in mind, while still providing plenty of real-estate to accommodate any attachment needs the end user may have.

The proprietary ATLAS attachment system is a very durable and an extremely dependable mounting platform that provides a trim profile without sacrificing the strength and stability customers have grown to love from Aero Precision handguards.
