This is the first upper in our line of NBS (No Bullshit) Upper Assemblies. 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, providing an upgraded extended latch charging handle and using reputable internals like the proven APOC Armory Black Nitride BCG paired with a Bear Creek 16" Mid-Length Barrel. 

This also means taking the time to ensure that the upper will function reliably even when used in adverse conditions. We dimple each and 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. 

Bottom line is this: you hear all the time about guys buying a budget upper and it not lasting or having to send it back because of some hardware defect or other issue caused by a careless assembly process. That is why we use brand name components,  assemble each unit to the highest standard of quality, and why we don't sell our uppers without pairing it with a BCG. We want your upper to function flawlessly out of the box. In fact, we guarantee it will.

I searched high and low,

I searched high and low, researched, looked and and looked more. I had narrowed it down to two uppers from another manufacturer. Then I saw this one. I compared what I got for the price and there was no question. This was the clear winner. This upper is clean, smooth functioning, and fits my lower like a glove. I am very glad I didn't pull the trigger on a different one. The nicer BCG, charging handle, and Bear Creek barrel sold me on it. Having it here, and on a lower, I know I made the right choice. The customer service was great. (I had a warranty question that was answered in an email in minutes...not automated, there was a dude on the other end at midnight my time). The shipping was great too. Ordered on Wednesday morning, the mailman handed it to me Friday morning. Cant go wrong here. I recommend it 100%.

I ordered this upper on

I ordered this upper on Tuesday, tracking info on Wednesday, arrived on Saturday. Fit and Finish is superb. Everything fits and looks perfect. The upper fits very nice on numerous brands as well as 80% lowers. This blows other bargain priced uppers out of the water by using better components where it counts, such as steels block, apoc bolt and extended charging handle. Package was carefully packed, I even got an email because they were concerned that the package did not scan in. I received it a few hours after the mail. Great job guys. I will be back again.
