Two thumbs up
The upper was exactly as advertised. Grateful to Stag for offering so many options for the Southpaw shooters out there. Haven’t built the rifle yet, but it appears to be of solid quality and should perform as expected. Feels good in the hands. AR15Discounts had in stock when many others didn’t and the upper assembly is as they advertised and pictured. Ordering was easy, quick and the item shipped and delivered really fast. Added to my core options of to go to websites to purchase!
