Full description and what we offer
Brock Armory specializes in custom AR-15 builds where you choose every component. Rather than selling off-the-shelf rifles, they work from a detailed quote system—you pick caliber, barrel length, trigger, charging handle, grip, gas block, and finish. Every rifle ships to your local FFL to complete the required federal Form 4473.
Their philosophy is straightforward: mil-spec is the standard, but manufacturers can still vary by fractions of an inch. That's why they pair barrels and bolts from the same manufacturer. As they explain it, "the barrel axis is the most important" part of a rifle that shoots well.
| Component | Starting Point | Premium Upgrades |
|---|---|---|
| Trigger | Mil-spec | Rise Armament 3.5lb ($110) or CMC Single Stage ($175) |
| Charging Handle | MIL-SPEC | Radian Raptor ($95) or Aero Precision Breach Ambi ($65) |
| Gas Block | Standard | Adjustable options ($50-$100) |
| Grip | A2 Plastic | Hogue Overmolded ($25) or Ergo Rubber ($18) |
| Cerakote | None | 1-color ($125), battleworn ($175), 2-color ($200), custom ($375) |

They operate by appointment only. Call 817-901-8626 or email [email protected] to discuss your build.
They have no pretense about cookie-cutter builds. If you want a specific brand on a particular part, they'll source it. They're focused on rifles that actually work—whether you need a range gun, truck gun, home defense, or hunting rifle.
