Sig Sauer TANGO6T
For those looking to upgrade to a first focal plane Low-Power Variable Optic (LPVO), the SIG SAUER TANGO6T FFP is a scope that delivers in both clarity and ruggedness. Originally developed with tactical engagements in mind, this scope has proven its versatility across a range of platforms, from ARs to bolt actions. I’ve had the chance to experience its 6x Super-Zoom Advanced Optical System and appreciate the glass-etched illuminated reticle, which adapts beautifully to any light, day or night. The TANGO6T’s construction combines durability with clarity, featuring HDX optics and SpectraCoat for impressive low-light performance. With its extreme waterproofing and abrasion-resistant lenses, it’s built to excel in the field.
Crimson Trace Hardline
The Crimson Trace Hardline 3-9x40 is built for shooters who need a no-nonsense, durable scope that handles everything from close to mid-range engagements. Featuring a second focal plane CT Custom BDC .223/5.56 reticle, it offers precise shot placement with its 1/4 MOA click adjustments. While testing this scope, I appreciated the exposed windage and elevation turrets, allowing for quick, easy adjustments without needing tools. Its aerospace-grade aluminum construction and nitrogen-purged, multi-coated lenses hold up well in harsh conditions, staying clear and fog-free. At just 15.2 ounces, it’s a lightweight yet tough addition to any rifle setup, backed by Crimson Trace’s complete lifetime warranty for extra peace of mind.
