What Is AR-15 Lower Receiver? 🔔
It is the part of an AR-15 Rifle that houses all of its major internal components such as the magazine well, fire control group (trigger), stock, grip, buffer tube, etc. It provides a frame or chassis for certain parts to mount onto and is typically made out of aluminium alloy or polymer. It also contains many other small precision parts like pins and springs that help keep it functioning properly.
Things To Consider Choosing Lower Receivers 🔥
🚩 Price – The price point will vary greatly depending upon the brand, construction type (aluminium or polymer), make/model, features included and any special finishes or engravings desired by you.
🚩 Quality – it should be your number one priority as this component holds all other important internal components together in order for them to work correctly.
🚩 Material – they will either be constructed from Aluminum Alloy or Polymer materials; both have their advantages but depending upon what kind of environment you plan on using them in should determine which material you should select from.
🚩 Engravings & Finishes – You may want to select a Lower with optional engravings or finishes aftermarket such as Cerakote coatings which provide better protection against wear & tear over time while also giving it an aesthetically pleasing look as well.

Lower Receiver Assembly 🎯
🔰 Starts by ensuring that all components are properly inspected before installation. All parts should be free of damage or deformations that could affect functioning. It is also important to use appropriate tools and lubricants during assembly.
🔰 Begin by attaching the buffer tube to the rear portion using two screws. This will provide stability for mounting the buttstock later on. Afterwards, the front pivot pin should be inserted into its corresponding hole within the Lower using an Allen wrench or similar tool.
🔰 Next comes installing a safety selector switch into its designated slot within either side of the Lower Receiver. Some models may require pressing down firmly with a hammer to ensure it seats properly in place. Once installed correctly, this will help ensure that accidental firing cannot occur while handling your firearm safely.
🔰 Once these steps have been completed successfully, attaching a buffer retainer pin onto its corresponding groove within the Receiver ensures that your buttstock stays secure during use.
🔰 After this step is complete, you’ll need to attach your fire control group (FCG) into its designated slot within the Receiver by pushing down firmly with a hammer until it’s flush against its surfaces inside of its respective cavity.
🔰 Once you have reassembled all components together successfully according to manufacturer guidelines or the instruction manual provided with purchase – it is now time to attach a bolt carrier group (BCG).

I read the article. Thanks. I have an aero lower receiver. I rely on dependable and economical Aero lowers, which are often easily obtainable.
I’m particularly fond of my Wilson lower. Being that it’s my first build, I was elated to find out that it possesses a set screw for the bolt catch release instead of having to drive in an uncomfortable roll pin through such a small hole – not fun at all! It could just be me, but this is something worth celebrating and made me appreciate life’s little pleasures even more.
Hi! Are lower receivers universal across all firearms?
Lower receivers are not universal across all firearms. Lower receivers come in many different sizes and calibres, so the type of lower receiver you need will depend on the type of firearm you are using. Additionally, some rifles may require additional components such as a buttstock or pistol grip in order to complete their lower receiver. Ultimately, it is important to carefully choose the right lower receiver for your specific rifle model.
Thank you for the post. Quite interesting. I noticed that not all lower features are the basic milspec features, allowing for ambidextrous controls, magwell funnels, and more. However, as others have suggested, almost every forged lower is produced by one of fewer than 10 OEM manufacturers with an array of different maker stamps.
We are grateful for your opinion
What is the good price for the lower receiver?
The good price for a lower receiver depends on a variety of factors, such as quality, manufacturer, and features. Lower receivers can range from a few hundred dollars for basic units to several thousand for more advanced models with higher-end components.
In my region, I consider a good deal for buying a receiver to be anything less than 200 dollars. Mine was purchased from Brownells at that price. The cost doesn’t have much of an impact on the performance
There are several elements that account for the variation in prices, including:
Whether or not it’s made to military specifications
The quality of its construction (forged is optimal, followed by billet and stamped)
Ambidextrous features (which can be a nice bonus).
What types of aftermarket products can I add to my lower receiver?
The aftermarket products available for Lower Receivers are almost limitless and range from stocks, grips, trigger guards and even trigger kits. Depending on the type of Lower Receiver you have, you may be able to find a variety of accessories that can enhance its performance or customize its look.
Good article. The information can be used for choosing a lower receiver. One piece of advice: remember, there are not many factories that produce lowers and these same plants provide for multiple companies. It’s all about consistent quality control as well as the logo or brand mark (some of which have greater appeal than others).
