We wanted to build an affordable upper assembly without cutting corners. This means using a nitrided steel gas block from an American Manufacturer as opposed to aluminum, quality American Made handguards and using a proven M16 profile nitride BCG paired with a NBS Premium Series 16″ Mid-Length Barrel.
This also means taking the time to ensure that the upper will function reliably. We dimple every barrel and check for excessive leaks in the gas system using compressed air. We use Permatex 242 on key components while using mil-spec AEROSHELL 33MS Anti-Seize grease on the barrel nut and muzzle device.

223 Wylde Upper
It was great working with them. They have fast delivery and the order is always correct. The upper looks fantastic - cannot wait to take it to the range.
USBest deal!
This is absolutely the best deal for not only a complete upper but a premium upper. I don't love the rail, but its quality and Great barrel n premium m16 bcg. However I got the wrong bcg. Now waiting for a response from tier 2 support to have the bcg exchanged. Well im positive they will. PSA always been my go to, n recommended upper to others. But ar15discounts.com, (as long as they swap the bcg) will be my number 1.. Seriously good luck finding a better deal, you won't I know everything..ha
