Royws - Barska IR SWAT Extreme 10-40x50mm Tactical Rifle Scopes 50mm w/ Rings

I mounted this scope on a .338 Lapua Magnum rifle and it performed flawlessly. It was very easy to boresight and range adjustments were smooth. The range of magnification (10-40x) exceeded expectations and parallax adjustments allowed a tight grouping of all shots. The scope is a sturdy piece of excellent engineering.
Pros: Ease of installation, accurate, smooth operation
