Introduction to Building an Affordable AR-15

Creating a budget-friendly AR-15 rifle is an exciting endeavor, allowing you to customize your firearm while staying within your means. With the right approach and some careful consideration, you can design an AR-15 that offers both quality and value. In this comprehensive guide, we’ll explore seven essential strategies to help you build the ultimate bargain AR-15, ensuring you get the most bang for your buck without compromising on performance.
1. Choose a Reputable Manufacturer

When it comes to building an affordable AR-15, selecting a reliable manufacturer is crucial. Opt for well-known brands known for their quality and affordability. Some popular choices include:
- Smith & Wesson
- Ruger
- Palmetto State Armory (PSA)
- Aero Precision
- Anderson Manufacturing
These manufacturers offer a range of AR-15 components and complete rifles at competitive prices, ensuring you get a reliable firearm without breaking the bank.
2. Opt for a Complete Upper and Lower Receiver Set

To save costs, consider purchasing a complete upper and lower receiver set. This approach simplifies the build process and often results in significant savings. Look for sets that include:
- Forged 7075-T6 Aluminum Receivers
- 16-inch M4 Profile Barrel
- 15-inch M-LOK Handguard
- Standard AR-15 Buttstock and Buffer Tube
A complete set like this provides a solid foundation for your AR-15 build, allowing you to focus on other components while keeping costs under control.
3. Select a Budget-Friendly Barrel

The barrel is a critical component of your AR-15, and choosing a cost-effective option is essential. Look for barrels with the following features:
- 4150 Chrome-Moly Vanadium Steel
- 1:7 or 1:8 Twist Rate
- Mid-Length Gas System
- 5R Rifling
- 16-inch Length
These specifications offer a balance between performance and affordability, ensuring your AR-15 functions reliably without straining your wallet.
4. Prioritize Quality Triggers

While triggers may seem like a minor component, they play a crucial role in the overall performance of your AR-15. Invest in a quality trigger to enhance your shooting experience. Look for triggers with the following characteristics:
- Single-Stage Design
- Pull Weight of 4-6 lbs.
- Mil-Spec or Drop-In Compatibility
- Reliable and Consistent Performance
A good trigger can make a significant difference in your AR-15’s accuracy and overall feel, so don’t skimp on this essential part.
5. Choose Affordable Sights or Opt for a Red Dot

When it comes to optics, you have two main options: iron sights or a red dot sight. Both can be budget-friendly choices:
- Iron Sights: Look for adjustable sights with a clear and crisp sight picture. They are affordable and reliable for close- to mid-range shooting.
- Red Dot Sight: Consider a basic red dot sight with a simple reticle and adjustable brightness settings. These sights offer quick target acquisition and are suitable for various shooting scenarios.
6. Explore Aftermarket Furniture Options

The stock and handguard of your AR-15 can significantly impact its comfort and handling. Explore aftermarket options to find affordable and ergonomic solutions:
- Stock: Look for adjustable stocks that offer length-of-pull and comb height adjustments. This ensures a comfortable fit for different shooters.
- Handguard: Consider M-LOK or KeyMod handguards, which provide modularity and the ability to attach accessories. Look for options with a comfortable texture and heat dissipation properties.
7. Build Your Own Lower Receiver

If you’re feeling adventurous and want to save even more money, consider building your own lower receiver. This process involves purchasing individual components and assembling them yourself. Here’s a step-by-step guide:
Step 1: Gather the Necessary Components

- Forged 7075-T6 Aluminum Lower Receiver
- Mil-Spec Trigger Guard
- Mil-Spec Fire Control Group (Hammer, Trigger, Disconnector, etc.)
- Lower Parts Kit (LPK): Includes Buffer Tube, Buffer, Spring, etc.
- Pistol Grip

Step 2: Assembly

- Begin by installing the trigger guard onto the lower receiver.
- Next, insert the fire control group components, ensuring proper alignment and secure fitting.
- Attach the lower parts kit, including the buffer tube, buffer, and spring.
- Install the pistol grip and ensure it is firmly in place.
- Finally, insert the Magpul PMAG to complete the lower receiver assembly.
