Sig Rotary Diopter Sight

by Doc, from TX, United States Written on January 28, 2017
This is a Good product if you happen to own a SIG 556 without iron sights. You never can tell when the SHTF and you might not have access to batteries for your SIG Romeo 5 or EoTech sights. I happen to think they look good also. Similar to the HK sights.

Where to begin...

I should start this review with an apology to Opticsplanet. I returned the item twice along with a nasty note about defective products. Turns out Sig is the one to blame.

I bought this item because the one included with my rifle broke. The mounting screw was stripped. When I received my first sight, the diopter wouldn't turn like is should. It would lock up and only turn less than 1/2 of what it should. I returned it. The second one did the same. I called Sig and they told me it was defective and suspected Opticsplanet send me the same defective item back again.

The third sight did the same thing. This time I decided I would use parts from my old sight and put them on the new base. After disassembling my old and new sights I saw how they work. Turns out Sig sends the sights so tightly assembled, the parts that should move independently are locked together.

If you buy this product and the diopter does not move easily and locks up (it should turn smoothly and have one click per 1/4 turn) then hold the diopter in place and turn the elevation control to the left/"down" until they are no longer stuck together.

The front sight is a pain also. I think the roll pin was too big. It shouldn't take that much effort to hammer in a pin.

A note for Sig. Selling rifles without sights was a poor choice. Selling the sights separately in this condition... W!!!! T!!!! F!!!!!! Also, the allen wrench included was very nice of you. The vague and limited instructions even mention that it's in...
