Description
The Timber Creek Outdoors Greyman GLPKU is a lower parts kit built to take your AR lower from a bare receiver to a functioning foundation. Timber Creek put the Greyman series together with the gunfighter in mind, redesigning some of their most popular parts and adding upgraded touches like crosshatch texturing, smoothed edges, and more billet aluminum than you'll find in a standard mil-spec kit. The Urban finish gives it that subtle gray look that reads clean and modern without shouting for attention.
What Sets the Greyman GLPKU Apart
The standout piece here is the ambidextrous safety selector. It's CNC-machined from aircraft-grade aluminum with modular levers, and you can set it up with either a 90-degree throw or a 45-degree short throw depending on how you like to run your rifle. Left-handed and right-handed builders both get an easy, natural reach. The steel takedown and pivot pins round things out and make breaking your rifle down a smoother job.
Building With the Greyman Urban Kit
This is a drop-in kit compatible with most mil-spec lower receivers, and it comes with the springs, detents, pins, bolt catch, and magazine release you need to finish the lower. Worth knowing up front: the GLPKU does not include a trigger, trigger guard, or pistol grip. That's by design, since it lets you pick the fire control group and furniture you actually want instead of paying for parts you'll swap out anyway. If you're chasing a specific trigger feel or a grip that fits your hand, this approach saves you the hassle.
Timber Creek is a family-owned outfit out of Springfield, Oregon, and they've earned a solid reputation for AR parts that look good and hold up. Everything in the Greyman line is backed by their lifetime warranty, which is a nice bit of peace of mind on a kit you're trusting to run your rifle.

Frequently Asked Questions
Does the Greyman GLPKU kit include a trigger and pistol grip?
No, the GLPKU does not come with a trigger, trigger guard, or pistol grip. Timber Creek leaves those out on purpose so you can choose the fire control group and furniture that suit your build. It does include the ambi safety, bolt catch, magazine release, takedown pins, and all the springs and detents you need for the rest of the lower.
Will this Greyman lower parts kit fit any AR-15 lower?
It's designed as a drop-in kit for most mil-spec AR-15 lower receivers. If your receiver follows standard mil-spec dimensions, the parts should install without issues. Non-mil-spec or proprietary receivers may need a closer look before you start the build.
What makes the Greyman ambidextrous safety selector different?
The Greyman ambi safety uses modular aircraft-grade aluminum levers that you can configure with either a 90-degree throw or a 45-degree short throw. That lets you tune it to your shooting style and gives lefties and righties an easy reach. It's a real upgrade over the basic single-side selector you'd get in a plain mil-spec kit.
Is the Greyman GLPKU kit backed by a warranty?
Yes, every Timber Creek Outdoors product, including the Greyman line, carries a lifetime warranty. Timber Creek is a family-owned company out of Springfield, Oregon with a strong track record on AR parts. If you run into a defect, they'll work with you to make it right.
