Q LLC The Fix *CA Compliant 308 Win 10+1 16" Picatinny Rail Receiver, M-LOK Handguard, Polymer Grip

The Q LLC The Fix is a California-compliant 308 Win rifle receiver built for shooters who need a modern, modular platform without the legal friction. If you're in CA and want to run a 308 Winchester with a traditional rifle layout—fixed magazine, Picatinny rail, and tactical ergonomics—this is the foundation you're looking for. The 16" receiver comes ready to build or upgrade, with an integrated Picatinny rail for optics and a slim M-LOK handguard that keeps weight down while giving you genuine mounting flexibility. The polymer grip rounds out a no-nonsense design that prioritizes function over flash.

This is a receiver platform, not a finished rifle, so you're starting with the core of a 308 build. The 10+1 configuration (10-round fixed magazine plus one loaded round) meets California requirements while staying practical for hunting, range work, and precision shooting. The Picatinny rail is rock-solid for mounting a scope, red dot, or other sight system, and the M-LOK slots on the handguard let you attach lights, bipods, or other accessories exactly where you need them. Whether you're hand-loading for long-range accuracy or running factory ammo for hunting, you've got a clean slate to customize.

Q has a reputation for purposeful, durable gear, and this receiver reflects that philosophy. The materials and fit are built to last, and the design is straightforward—no marketing gimmicks, just functional engineering. California shooters often find themselves compromising on features; this platform doesn't ask you to sacrifice capability just because of the state you live in.

Frequently Asked Questions

Is this a complete rifle or a receiver kit?

This is a receiver platform—the core component of a 308 rifle. You'll need to source a barrel, bolt carrier, and other components to complete the build, or work with a gunsmith to finish it. It's not a plug-and-play rifle out of the box.

Does this work with standard 308 Winchester ammunition?

Yes, it's chambered in 308 Winchester and will accept factory and hand-loaded 308 rounds. The 10+1 capacity is set by the fixed magazine design required for California compliance.

Can I use standard AR-pattern accessories on the M-LOK handguard?

The M-LOK slots will accept any M-LOK-compatible accessories—lights, bipods, grips, and rail sections designed for that standard. The Picatinny rail on the receiver is compatible with standard Picatinny-mount optics and attachments.
