Aero Precision M5 Multi Receiver

Aero Precision M5 Receiver Set + Nickel Boron BCG & Charging Handle – "Big Bore Ready"

Built on Aero Precision's legendary M5 platform, this complete upper/lower receiver set is the foundation for a serious .308/6.5 Creedmoor build. Precision-machined from 7075-T6 aluminum with tight tolerances and a hardcoat anodized finish that laughs at rust and abuse. Enhanced Type III anodizing keeps it looking sharp while shrugging off range grime.

Paired with a premium nickel boron BCG—slick, corrosion-resistant, and easy to clean. The NiB coating reduces friction for smoother cycling, faster lock-up, and less carbon buildup. Runs cooler under heavy strings, and that gold finish looks mean as hell when you rack it.

Includes a  charging handle smooth operation, and no sharp edges to chew up your hands.

This isn't a budget build kit—it's the core of a rifle that runs hard, stays reliable, and carries the 2A Arms promise: no shortcuts, no excuses. Whether you're hunting big game, ringing steel at 1,000 yards, or building your next DMR, this M5 set + NiB BCG + charging handle gives you the platform to dominate.

Ready for your barrel, handguard, and trigger of choice. Bolt it together, zero it, and go own the range.
