Great sights for the budget concious
by Zane Maurer
Not much that can be said about these sights that hasn't already been said.The construction is of good quality, and adjustments are precise.I prefer steel sights, but for the budget build these are hard to beat.
Great Sight
by Paul Toon
Ordered this and some other parts to finish out my build. Primary Arms had the pieces I needed and at a price equal to or less than the other vendors. They shipped out my parts quickly and I had my parts in short order to finish my AR build. I have ordered parts from Primary Arms in the past and will continue to use their services.
Great low budget option

Product was shipped so quickly I honestly couldn't believe it. If you need something, and want an assurance of quality & timely service, Primary Arms is the place to get it. I continue to be totally impressed with their fantastic customer service.
