Key Considerations
Budget
Like other accessories (stocks, handguards, vertical grips, foregrip bipods, buffers, etc.) upper receivers come at different price points, so you need to discern how much you are willing to pay for your new AR build. You may also want to consider the parts’ materials and quality and weigh if the cost you are willing to pay compensates just like most buyers do. Only get one that you can afford or learn the cheapest way to build your AR-15.
Durability
The receiver part’s durability lies in its manufacturing type. Forged stripped upper receivers are heavier, but they are sturdier and more durable. In contrast, machined receivers are lightweight but not as durable. Cast receivers are in between the two.
You may want to look for receivers made of 7075 T6 like the Aero Precision because it is the highest strength alloy of aluminum, possessing high fracture toughness and low fatigue crack growth. [1]

Practicality
We encourage you to get a receiver part that has sturdy quality materials. However, if the price range is beyond your budget, you may want to be more practical. Choose an upper or lower that fits your AR build perfectly but is still in the price range you have set.
Compatibility
When we tested the receivers, we discovered that not all complete receivers could be used with all the lower receivers.
Hence, we recommend that you only buy a high-quality receiver part that will be a perfect fit for your rifle. It shouldn’t pose as a distraction to your rifle’s rear sight like other attached tools.
Also, consider things like barrel length, gas system, type of gas block, free-floating handguards, and angled foregrips. Looking for an upper that can fit other weapons you may want to use is also better. We recommend that you consider ease of disassembly, as well.
Choosing Between An Upper and A Complete Gun
Choosing between an upper and a complete gun may be challenging, especially if it is your first time doing your build. Some people may tell you that buying a high-quality complete gun is better and less hassle.
However, buying receiver parts will save you a lot of money while also giving you the chance to customize your weapon. Aside from uppers and lowers, you may also install a free float AR quad rail to make it more functional. You’ll also learn many things while building your AR pistol build. Somehow, it will give you an amazing sense of pride. It’s your call.
