The Black Rain Ordnance Professional in gray is a semi-automatic .22 LR rifle built around a T6 billet aluminum receiver and a threaded PROOF Research carbon fiber barrel. The carbon fiber barrel cuts weight and handles heat better than a standard steel tube, which matters during longer range sessions. The gray Cerakote finish gives it good corrosion resistance and a clean look.

Detailed Features 

The Luth-AR MCA-22 stock adjusts for length of pull, which makes the rifle fit a range of shooter sizes without modifications. The trigger breaks at 3.5 lbs — light enough for clean shots without being hair-trigger territory. The 18.5-inch threaded barrel is suppressor-ready and provides good muzzle velocity for a .22 LR platform. 
 
The T6 billet receiver is machined to tighter tolerances than a standard cast receiver, and .22 LR's low recoil means the rifle stays comfortable through long sessions. It ships with one magazine; higher-capacity options are available but have been a point of discussion among owners who want more feeding flexibility. 
 
This is a purpose-built .22 LR that punches above most budget rimfire rifles on materials and fit. It works well for range training, small game hunting, and general plinking. The price reflects the carbon fiber barrel and billet construction — worth it if those specs matter to you, less so if you're looking for a simple plinker.

Owners of the Black Rain Pro Gray generally like it. The carbon fiber barrel gets mentioned often as the defining feature — it keeps the rifle light enough to carry comfortably and holds up well during extended range sessions. The semi-automatic action runs reliably, and the .22 LR caliber keeps ammo costs manageable for regular practice.

Accuracy at typical rimfire distances draws consistent positive comments, and the adjustable Luth-AR stock is appreciated by shooters who want a fit that actually suits them.

On the critical side, some owners have raised questions about long-term durability of the carbon fiber components under hard use, though most report no issues in normal conditions. Magazine compatibility and capacity availability have come up as practical concerns — a few buyers wish there were more high-capacity options readily available.

The price is the most common friction point. Some feel the carbon fiber barrel and billet construction justify the cost; others think comparable performance is available for less. It's a fair debate. For competitive or heavy-use shooting, a few owners have noted it may not fully meet those demands, but for training and plinking it holds up well.
