Complete Polymer AR-15 Lower Receiver: Benefits, Comparisons, and Tips

The complete polymer AR-15 lower receiver is a great alternative to traditional metal receivers. With advancements in technology and material science, polymer has become an increasingly popular choice for rifle components.

In this article, we will discuss the benefits of using a complete polymer AR-15 lower receiver. We will also compare it to traditional metal receivers and provide tips on how to properly maintain your polymer receiver.

What is a Complete Polymer AR-15 Lower Receiver?

Before we dive into the benefits of using a complete polymer AR-15 lower receiver, let's define what it actually is. A lower receiver is the part of the gun that houses the trigger group and magazine well. It serves as the foundation for all other components that make up an automatic rifle.

A complete polymer AR-15 lower receiver is made entirely out of high-strength reinforced polymers such as nylon or fiberglass-reinforced plastic (FRP). The use of advanced materials makes these receivers lightweight yet durable enough to withstand harsh conditions like heat, cold weather or hard impact with minimal wear-and-tear compared with their metallic counterparts.

Benefits of Using Complete Polymer Lower Receivers

  1. Lightweight
    Polymer lowers are much lighter weight than aluminum or steel lowers making them ideal for transporting around during tactical operations without causing fatigue over extended periods which can negatively impact performance outcomes when most needed.
  2. Durable
    Polymer materials used in constructing these lowers are not only lightweight but also highly durable thanks to their advanced engineering techniques which incorporate features such as multi-layered architecture designed specifically for shock absorption & resistance against corrosion.
  3. Affordable
    Compared with traditional metal alternatives like aluminum or steel which can cost hundreds more per unit while still being prone towards rusting out over time requiring frequent cleaning; choosing either Nylon-based compounds (e.g., Zytel®), glass fiber filled plastics (e.g., Acetron GP®) etc. offers a cost-effective alternative that still provides high-performance characteristics in even the most demanding environments.

Comparing Complete Polymer AR-15 Lower Receivers to Traditional Metal Receivers

Now let's take a look at how complete polymer AR-15 lower receivers stack up against traditional metal receivers:

  1. Weight: As mentioned earlier, polymer lowers are much lighter than their metallic counterparts. This makes them easier to carry and maneuver during tactical operations.
  2. Durability: While some may argue that metal is more durable than plastic, modern polymers have proven themselves just as rugged and reliable as metal while being able to better absorb shock due its multi-layered composition design thus making it less prone toward deformation or cracking under stress.
  3. Affordability: Polymer is cheaper compared with aluminum or steel lowering the overall costs of production for manufacturers which they can pass on to consumers; this also brings down maintenance expenses over time since these lower retain their shape longer despite constant use without corroding like metals do over time leading towards rusting out.

Tips for Maintaining Your Complete Polymer AR-15 Lower Receiver

Maintaining your complete polymer AR-15 lower receiver requires minimal effort compared with traditional metallic ones but it's important not neglect routine cleaning or lubrication tasks otherwise you risk compromising its performance capabilities.

To keep your polymer receiver in tip-top shape, follow these guidelines:

  1. Regularly clean and lubricate all moving parts like springs, trigger mechanisms etc – frequently inspecting components such as magazine well release buttons which can be prone towards accumulation of debris resulting in jamming situations
  2. Avoid exposing your rifle to prolonged exposure extreme temperatures especially above 130°F (55°C), direct sunlight & harsh chemicals/drugs e.g., gasoline-based solvents containing acetone/chlorinated compounds will cause drastic reduction service life.
  3. Store your rifle unloaded when not in use – storing it in an environment with low moisture levels and out of direct sunlight can help prevent damage from corrosion, rust buildup or warping over time.

Conclusion

In conclusion, a complete polymer AR-15 lower receiver is a great alternative to traditional metal receivers. With its lightweight and durable construction, it offers users several benefits including affordability and ease of maintenance.

While some may argue that metal provides better durability than plastic when it comes to firearms components like lower receivers; modern polymers engineered with reinforced multi-layered architecture have proven themselves just as rugged while being able to absorb shock better due their natural composition thus making them less prone towards deformation or cracking under stress.

Overall, choosing either Nylon-based compounds (e.g., Zytel®), glass fiber filled plastics (e.g., Acetron GP®) etc. offer cost-effective alternatives that still provide high-performance characteristics in even the most demanding environments whilst requiring minimal maintenance efforts compared with metallic counterparts which makes them ideal for those who need reliable weapons without the extra hassle or expense.

FAQs

What is a complete polymer AR-15 lower receiver?

A complete polymer AR-15 lower receiver is a foundational component of an AR-15 rifle. It includes the lower receiver, pistol grip, trigger assembly, buffer tube, and stock assembly. The primary difference between a traditional aluminum lower and a polymer one is the material used in its construction. Polymer lowers are made from reinforced nylon or other high-strength polymers that offer several advantages over their metal counterparts.

Polymer lowers tend to be lighter weight than aluminum ones while still maintaining high levels of durability and strength. They are also resistant to corrosion, rusting and resist impact damage better than traditional materials which means they will last longer without showing wear or tear.

The Complete Polymer AR-15 Lower Receiver has all components needed for use with any standard Mil-spec Upper Receiver including buffer tube assembly (MIL-SPEC), trigger group parts kit (MIL-SPEC), pistol grip (A2 style) & bolt catch/release lever.

Are there any differences between polymer versus metal versions?

Yes! While both types can function identically in an AR build when installed properly; there are some differences you should consider before choosing which option to purchase for your next build project.

Polymer receivers tend to be less expensive than their metal counterparts because they require less machining effort during production due to being molded instead of CNC machined from blocks of solid materials like aluminum would need as raw material input.

Polymer equivalents have been known -in general terms-on occasion-to not fit quite as snugly into upper receivers resulting in wobble or leeway where accuracy can become compromised if not addressed properly before installation begins.

Is it legal to own/assemble this kind of gun?

Yes! As long as you meet all legal requirements set forth by your local authorities regarding firearms ownership within your state/country then law enforcement do not view "complete" Polymer Receivers differently from other "complete" AR receivers.

What is the durability of a complete polymer AR-15 lower receiver?

The durability of a complete polymer AR-15 lower receiver can vary depending on the quality & manufacturer. However, most well-made polymers are tough and durable enough for long-term use without showing wear or tear. In addition, they are resistant to corrosion and rusting.

Polymer is an excellent material choice in that it's also very lightweight compared to aluminum counterparts-not only does this mean less weight being carried around but it also reduces recoil felt when firing your weapon so you're able to shoot accurately with little fatigue during an extended range session.

How do I install a complete polymer AR-15 lower receiver?

Installation instructions will depend on what specific product you purchase. However, generally speaking: installation steps involve removing any existing stock assembly from your current rifle; installing the buffer tube assembly into your Polymer Lower Receiver (ensuring that parts remain properly aligned); installing pistol grip & trigger group parts kit per MIL-SPEC guidelines; then applying Loctite adhesive onto both sides of Bolt Catch/Release Lever Threads before tightening them down securely onto their respective hardware points using proper tools such as torque wrenches etc.

It's important to follow all instructions provided by the manufacturer carefully as each brand/model may have unique requirements which-if ignored-could result in damage/the need for repairs later down-the-line!
