Frequently Asked Questions

What is included with this receiver?

The M5308 Win M5 Platform is a stripped receiver body only. It does not include a fire control group, grip, bolt carrier group, or barrel. You'll need to source these components separately to complete your rifle build.

What is the M5 platform?

The M5 is Aero Precision's larger-format AR platform, designed for magnum cartridges and precision rifle applications. It maintains AR-ergonomics while scaling up the receiver and magazine compatibility compared to the standard M4 platform.

Can I use standard AR-15 components with this receiver?

No. The M5 platform is a larger format and requires M5-specific components—barrels, bolt carrier groups, magazines, and other parts. Standard AR-15 (M4 format) components will not fit.

Is this receiver 80% finished or fully machined?

This is a fully finished receiver, not an 80% blank. It is ready to accept components and function once you've installed all necessary parts.
