AERO PRECISION M4E1 PRO

Overview

The Aero Precision M4E1 PRO platform brings premium, fully ambidextrous control and heavy-duty component upgrades to their popular M4E1 line. While the PRO series is widely known in its standard 16-inch rifle configuration, a complete pistol configuration utilizes a shorter barrel (such as 10.5" or 11.5") paired with a stabilizing brace.The Core UpgradesFully Ambidextrous Controls: The PRO lower receiver features mirrored, factory-installed ambidextrous controls. This includes the safety selector, magazine release, and a unique dual bolt catch/release lever.Upgraded Bolt Carrier Group: It features the Aero PRO Lineup BCG. The bolt is individually high-pressure tested (HPT), magnetic particle inspected (MPI), made from Carpenter 158 steel, and features a chrome-lined interior with a phosphate exterior coating.Premium Trigger: It replaces the standard mil-spec trigger with an ALG single-stage trigger control group for a much cleaner break and a lighter pull.Heavy-Duty MOD 4 Handguard: The pistol upper includes the new MOD 4 rail system. It features an aggressive, high-rigidity lockup system with integrated M-LOK slots and quick-detach (QD) sling points.Cold Hammer Forged Barrel: The platform swaps standard barrels for premium Ballistic Advantage Cold Hammer Forged (CHF) chrome-lined barrels to ensure long-term durability and heat resistance under rapid fire.Lower Receiver FeaturesFlared Magwell: Machined with an aggressively flared magazine well to allow for incredibly fast and intuitive reloads.Integrated Trigger Guard: The guard is machined directly into the 7075-T6 aluminum forging to increase rigidity and safely accommodate gloved hands.H-Buffer System: Includes a heavier H-buffer setup to mitigate recoil and smooth out the cycling of shorter gas systems.Threaded Assembly Pins: Uses a threaded bolt catch pin and an upper tension screw to eliminate receiver wobble and prevent finish scratches during maintenance.This one has a Trigger Tech trigger installed, an adjustable gas tube and DPB Rearden muzzle device attached as well.
