Sig Saur Buckmasters 3-9×40

with No Comments

Sig Saur is a Swiss firearms company with an historic reputation for making rifles and pistols built to Swiss engineered quality. But recently they’ve also been releasing a line of accessories and optics at a competitive price like their popular Romeo line of red dots. Their Buckmasters 3-9x40mm is their least expensive magnified hunting scope at around $100 or under.

Unlike other budget price tier 3-9x scopes, the Buckmasters appears to be well built. It has a tight and well built tube with clear markings and smooth moving components. A good indication is the moulded SIG branded lens caps. A company that was just cashing in their brand on trash optics would have settled for unbraded caps or cheap printing on generic caps.

Typical of hunting scopes, the caps are capped which protects the turrets from the elements, moisture, and accidental bumps. The turrets are resettable using the included Allen wrench. They turn with nice audable clicks and are tactile positive, with only a little slop. In testing, the turrets returned to zero in box tests.

The scope has a BDC reticle but oddly manual doesn’t provide information as to the ammo and rifle used to establish the reticles dope markings. Perhaps this is an admission to the failure of this reticle type to live up to its promise because it’s unlikely the buyer will have the exact same rifle and use the exact same ammo. That said, I prefer reticles with any type of hold mark to provide a reference point for applying hold overs with follow up shots.

Optically, the scope’s sharpness and resolution was typical of 3-9x, in the Group -2 category using a 8.5″x11″ USAF Optical Resolution chart at 100yrds. But unlike typical budget scopes, the Buckmasters displayed no chromatic aberration and maintained an even sharpness and focus from center to edge. In addition, the scope maintained about a 3.5″-4″eye relief and decent eye box.

For the price, this scope exhibits better optics than the similarly priced Bushnell Banner and much better build quality and clarity than cheaper CVLife and other no-name scopes. It does have a limited lifetime warranty which isn’t as forgiving as Vortex’s but if you don’t abuse your gear, it should be effectively the same.
