My Experience, Good Receiver.
I just wanted to share my two cents, I had read the previous reviews of the billet receiver not being able to fit a charging handle. I really wanted a different look, so this receiver was my first choice. When it arrived, I tested it with two different charging handles over a BCG. Everything is golden. The receiver itself is great. Threads are sharp and consistent, gas rod hole is centered, finish is flawless, charging handle latch pocket is cut deep, and it fits snug over my lower with absolute minimal rattle. My experience is that this is worth every penny.

I couldn't figure out how to edit my previous review so I am writing a new one. Even though I was past the return window, AR15Discounts replied to my review and made good on their promise. They allowed me to return my bad receiver, sent a prepaid shipping label, and quickly sent me a new receiver once they received the return. The new one fits beautifully and looks amazing. It actually looks nice with both forged and billet lowers because it has sharper lines and a more modern look, without being over-the-top "boutique" or bulky, and keeps the lightweight aspect as well. I have already purchased another one and intend to purchase more for future builds. Thanks to the AR15Discounts team for getting me taken care.

USPretty good for the price
AR15discounts replaced my original one that had misaligned feed ramps. Second one was much better. Some slight tooling marks behind the shell deflector, but otherwise finish was excellent. Clean understated, but still billet look. Overall a good upper, especially for the price. One suggestion for NBS if they do a version 2: either add a threaded forward assist pin or a relief cut for the forward assist roll pin hole. It is too close to the side of the receiver and there is no way to install the roll pin without hitting your receiver with the edge of the roll pin punch.
USDecent product for the price
Pleased with the product. Being priced so low, wasn’t sure what to expect. But I am happy I bought. Lots have complained about it not fitting, not a complaint here. It does fit tighter due to being billet. I would buy again with knowing not to expect a lot with the price point.
