Black Rain BRO-22 Billet Receiver Overview
Black Rain Ordnance is known for precision-machined AR rifles, and the BRO-22 line brings that same billet craftsmanship to the rimfire world. Starting with a billet receiver gives your build a rigid, precisely machined core, a scope rail that will not shift, and a look that stands apart from a standard cast receiver.
6061 T6 Billet Aluminum
Machining from a solid billet produces tight tolerances and crisp lines. The 6061 T6 aluminum is light yet strong, so the receiver adds rigidity to your build without adding unnecessary weight.

Integral Picatinny Rail
The rail is machined into the top of the receiver rather than bolted on, so your optic mount sits on a solid, consistent surface. That helps your rifle hold zero through bumps, temperature swings and repeated scope changes.
Type 3 Hard Coat Anodize
The black hard coat anodize finish resists scratches, corrosion and wear far better than paint. It gives the receiver a clean, durable finish that will look good for years of range sessions and hunting seasons.

Built for Standard Parts
The receiver is designed around industry-standard semi-automatic 22 LR components, so you can pick the barrel, trigger group, bolt and stock you prefer and assemble a rifle that fits exactly how you shoot.
Why Builders Choose Billet
Many shooters enjoy building a rimfire rifle as much as shooting it. Picking each component lets you balance weight, accuracy and budget exactly the way you want, and the finished rifle is truly yours. A quality billet receiver is a smart place to invest, because every other part bolts to it and relies on it for alignment.
Planning Your Build
Decide early how you will use the rifle. A lightweight tapered barrel and a sporter stock make a great small-game rifle, while a heavy or carbon barrel, a match trigger and an adjustable stock suit rimfire competition. Choose parts from reputable makers and check compatibility notes before ordering.
Assembly Tips
Install the bolt, recoil spring and charging handle before the barrel, torque the barrel retainer to the maker spec, and confirm the bolt locks back and cycles smoothly by hand. Function check the trigger and safety before live fire.
Choosing Ammunition
Once built, try a few quality high-velocity loads and a match load or two to see what your barrel likes best, then stock up on that lot.
Safe Storage at Home
Store firearms unloaded in a locked safe or cabinet with ammunition kept separately, and teach everyone in the household basic safety rules.
