M5 Carbine Complete Lower Receiver with MOE SL Grip and SL-S Carbine Stock

Product Description

The M5 Carbine Complete Lower Receiver with MOE SL Grip and SL-S Carbine Stock is a factory-assembled .308 AR lower from Aero Precision. This serialized firearm arrives fully assembled with a carbine buffer system, MOE SL pistol grip, and SL-S adjustable stock.

This lower is built on the M5 platform, which is designed for .308 Winchester and 6.5 Creedmoor chamberings. It mates with M5 and DPMS-pattern .308 upper receivers.

A complete lower eliminates the time and tooling needed to assemble individual fire control, buffer, and stock components. You add your preferred upper receiver and you’re ready to function-check.

What Upper Receivers Fit the M5 Lower

The M5 lower receiver accepts Aero Precision M5 uppers and most DPMS-pattern .308 upper receivers. The M5 platform uses a larger receiver extension and buffer system than AR-15 lowers, so .223/5.56 uppers are not compatible.

Before you buy an upper, verify the manufacturer’s pattern specification. Some proprietary .308 AR systems use non-DPMS dimensions and will not mate correctly.

Complete Lower Versus Stripped Lower

A complete lower ships with trigger assembly, buffer tube, buffer, spring, stock, and pistol grip installed. A stripped lower is just the serialized receiver casting with no internal or external parts.

Complete lowers save time if you prefer factory assembly and standard components. Stripped lowers let you select every trigger, stock, and grip to your own spec, but require more tools and know-how.

How the MOE SL Grip and SL-S Stock Compare

The MOE SL grip is a slimmer profile than Magpul’s standard MOE grip, with a steeper vertical angle that suits shooters who prefer a higher, more compressed wrist position. The SL-S carbine stock is a compact, six-position design with a reduced cheek weld profile and a friction-lock lever.

Both components are polymer. The stock rides on a mil-spec carbine buffer tube.

Frequently Asked Questions

Q: Is the M5 lower compatible with AR-15 uppers?

A: No, the M5 lower is built for .308 AR uppers and uses a larger receiver dimension and buffer system than AR-15 platforms. You need an M5 or DPMS-pattern .308 upper to complete this firearm.

Q: Does the M5 complete lower work with DPMS-pattern uppers?

A: Yes, Aero Precision M5 lowers are designed to accept DPMS-pattern .308 upper receivers. Always verify dimensional compatibility with the specific upper manufacturer before assembly.

Q: What buffer system does this lower use?

A: This lower is assembled with a carbine-length buffer tube and carbine buffer system sized for the M5 .308 platform. The tube accepts standard carbine stocks with mil-spec dimensions.

Q: Can I replace the stock and grip on this complete lower?

A: Yes, both the SL-S stock and MOE SL grip are removable. The stock rides on a mil-spec carbine buffer tube, and the grip attaches with a standard grip screw. You can swap either component with aftermarket alternatives.
