The Noreen ULR is a single-shot bolt-action rifle chambered in .50 BMG. The 16.5-inch barrel is shorter than most .50 BMG rifles on the market, which reduces overall length at some cost to muzzle velocity. The Timney adjustable trigger and Noreen-designed muzzle brake are standard.

Features 

 
The Timney adjustable trigger allows customization of pull weight to the shooter's preference. The minimalistic aluminum stock keeps the design pared down -- no cheekpiece adjustability or folding mechanism, just a functional platform. The Noreen muzzle brake reduces recoil considerably, which matters at .50 BMG pressures. At 16.5 lbs it's heavy for carry but light for a .50 BMG rifle. 
 
Single-shot operation means deliberate loading between shots. At .50 BMG, that's not a drawback for the intended use cases.

The Noreen ULR draws a consistent group of buyers: people who want a .50 BMG at a lower price point than the Barrett or other established names. Most feedback centers on a few clear themes.

The short 16.5-inch barrel relative to typical .50 BMG rifles comes up often. Shooters accept the velocity trade-off for the reduced overall length, though some note the increased muzzle blast compared to longer-barreled alternatives.

The Timney trigger gets positive marks. It adjusts well and most owners find the pull clean and consistent.

The muzzle brake does its job. Recoil from a .50 BMG is substantial and the Noreen brake makes the rifle shootable without a benchrest setup.

Weight is noted as a factor for transport. At 16.5 lbs it's not a rifle you carry long distances.

Ammo cost is a recurring practical concern in discussions -- .50 BMG is expensive, which limits practice volume for most owners. Pricing for the rifle itself is generally considered competitive for the caliber.
