What is AR 9 Lower Receiver? 🤔
It is the part of the firearm that houses all other components and allows for movement when firing a round. The lower receiver typically consists of an aluminium alloy forging, with internal parts made from high-strength steel, stainless steel or polymer.
Features 🔥
🎯 Material – It can be made from various materials such as aluminium, polymer, or steel, with each offering its own set of benefits.
- 💥 Aluminum Receivers are lightweight yet strong enough for most AR 9 applications. Their strength and light weight make them an ideal option for those who want a durable AR 9 platform without adding extra weight to the rifle. They are also relatively easy to install since they usually come with pre-drilled holes for mounting components like triggers, grips, and magazine releases.
- 💥 Polymer Receivers offer an even greater reduction in weight compared to their aluminium counterparts. While still strong enough for most AR 9 applications, these lower receivers often have fewer features than aluminium lowers and do not require any drilling for mounting points.
- 💥 Steel Receivers are some of the toughest available on the market today. These lower offer superior strength and durability when compared to other materials like aluminium or polymer; however, they can add quite a bit of unnecessary weight to your AR 9 rifle if you’re not careful.
🎯 Finish -the receivers come with a variety of finishes that all offer different advantages and disadvantages depending on your specific needs.
- 💥 Anodizing provides a hard protective coating that is both corrosion and wear-resistant. Anodizing also gives a nice-looking matte black finish.
- 💥 Cerakote is a ceramic-based product applied as a thin-film coating for Lower Receivers. It’s designed to provide improved durability, chemical resistance, lubricity, and corrosion protection with any AR build you may have in mind.
- 💥 DuraBake is another type of finish that provides enhanced corrosion resistance as well as abrasion resistance against wear and tear from regular use. DuraBake also offers chemical protection.
- 💥 Polymer finishes are applied by dipping the receiver in a polyurethane material giving it a slightly glossy look. Polymer finishes are lightweight and generally provide good protection against wear and tear.
🎯 Size – to accommodate AR-9 magazines, the lower receiver must be designed with a broad enough magazine well. An AR-9 lower should also have sufficient room for all other components such as triggers, handguards, stocks, etc., so it should measure at least 8″ in length. The width of the AR-9 lower receiver will depend on its intended application and can vary from 1/2″ up to 3/4″.
Cleaning Guide 🚿
🟨 Begin by removing any furniture or components such as stock, handguards or grips that may interfere with cleaning.
🟨 Next, use a stiff brush to carefully brush out any carbon deposits that build up on the inside of the lower receiver or around any internal parts. If necessary, you can also use a solvent to help break down carbon deposits more quickly and thoroughly.
🟨 Now it’s time to clean out any debris such as dust or dirt that may have accumulated within its cavities over time. To do this you should use a compressed air canister (or air compressor) and blow out any debris not removed by brushing earlier.
🟨 You should then finish off by wiping down all interior surfaces with a clean cloth which will help keep dust and other particles from settling into hard-to-reach areas within your AR 9 lower receiver in the future.
🟨 After that you can move on to reassembling your AR 9 lower; however, before doing so it’s important that you lubricate all interior surfaces with a quality guns oil – this will help protect against rust as well as ensure optimal operation when firing round through it later on down the line.
🟨 Additionally, if you wish to add additional protection against corrosion you could always spray some WD-40 into the inner parts of your AR 9 Lower Receiver prior to reassembly – this can provide further protection against moisture damage in humid climates.

It can cost anywhere from $100 to $3000 depending on the specific model, quality, and features. Generally speaking, AR 9 Lower Receivers with simpler designs and fewer features tend to be less expensive than those that come with more bells and whistles.
I bought my Ghost receiver kit for 6K dollars. Is it a lot? Not think so
Thank you for the article. I was impressed with one thing))) CLEANING))) OMG! Is it necessary to clean the lower receiver? I have had one for a year and have never thought about this ( oh, forgive me my gun)))
Yes, it is important to clean your AR 9 Lower Receiver regularly.
🔴 To do this effectively, use a degreaser or cleaning agent specifically designed for AR 9 Lower Receivers. Make sure to apply it properly and follow all instructions carefully to avoid damaging the receiver or any other components of the AR-9 rifle.
Yes, certainly. I do it after high round count rifle class. To ensure a thorough clean, I first separated the upper and lower portions before hosing down the lower with non chlorinated brake cleaner. To completely dry everything off, blow this section with compressed air and finish by spraying on aerosol eezox or your chosen lubricant for extra protection.
During an ordinary clean, I use my standard cleaners with patches and q-tips until it’s satisfactory. Afterwards, a light coat of oil to all the parts in the lower is applied for optimal performance which helps protect against rust accumulation.
It is advised that at least every 5 years or after 5000 rounds, you should be performing a thorough cleaning of your firearm. As oil breaks down and collects fouling over time, gunk begins to build up as well as rusting springs – so if running suppressed firearms more frequent cleanings are recommended.
To keep my air compressor in top condition, I use a routine of blowing out lint, dust, seeds, and old oil with regularity. Following this step up by adding Mobile 1 and then getting rid of the excess – it’s much easier than completely stripping down for maintenance. To ensure optimal performance is maintained every two weeks should do the trick, I believe so
