Building an AR-15 from scratch offers a unique opportunity to create a firearm tailored to your needs, preferences, and budget. One of the essential components of this process is the lower parts kit (LPK). This kit includes various components necessary for the assembly of the lower receiver, including the trigger, hammer, and safety selector. To ensure a successful build, here are eight must-know tips before buying an AR-15 lower parts kit.
1. Understand the Components Included
Before purchasing an ar15 lower parts kit, familiarize yourself with its components. A standard AR-15 lower parts kit typically includes:
- Trigger and Hammer: These are crucial for the firing mechanism.
- Safety Selector: Allows you to engage or disengage the firing mechanism.
- Trigger Guard: Protects the trigger from accidental discharge.
- Pistol Grip: Provides a comfortable hold for the user.
- Magazine Release: Enables quick mag changes.
- Bolt Catch and Release: Holds the bolt open on an empty magazine and reloads when the bolt is released.
Check the contents of the kit you are considering to ensure that it includes everything you need for your build.
2. Consider Quality Over Price
While it may be tempting to opt for the cheapest option, quality should be your primary concern when selecting an LPK. Affordable kits often use subpar materials that may lead to reliability issues, function failures, or a short lifespan.
- Reputable Brands: Look for kits from well-known manufacturers such as Bravo Company Manufacturing (BCM), Daniel Defense, or Palmetto State Armory. These brands have established a reputation for producing high-quality components.
By investing in a reliable LPK, you’ll increase the overall performance and lifespan of your rifle.
3. Check for Compatibility
Make sure the lower parts kit you choose is compatible with your lower receiver. While most AR-15 lower receivers are designed to work with standard components, there can be exceptions based on manufacturer specifics.
- Mil-Spec vs. Commercial: Most LPKs are designed for mil-spec lower receivers, but some manufacturers might offer proprietary designs that require specific parts. Verify that the components match the specifications of your receiver.
Ensuring compatibility will save you from potential headaches during assembly.
4. Evaluate Trigger Quality
The trigger is one of the most critical components of your AR-15 lower receiver, affecting your shooting experience significantly. Different triggers vary in pull weight, travel, and reset, all of which can impact accuracy and performance.
- Standard vs. Upgraded Triggers: Some lower parts kits come with basic triggers, while others might offer upgraded options. Consider opting for a kit that features a better-quality trigger if your budget allows, as this can greatly enhance your shooting experience.
If the kit you want has a standard trigger, you can also plan to upgrade it later as part of your custom build.
5. Review Installation Instructions
Before purchasing an LPK, check if the kit comes with comprehensive installation instructions. Some brands provide detailed manuals, videos, or online resources that can enhance the assembly process.
- Ease of Installation: A kit that provides clear instructions can significantly simplify the build process, especially for first-time builders. Look for guides that outline the assembly step-by-step.
If possible, read reviews from other builders to see how effective the kit’s instructions are.
6. Factor in Customization Options
As you build your AR-15, you may want to customize certain components to enhance performance or aesthetics. Some lower parts kits allow for upgrades or replacements of specific parts.
- Modular Components: Look for kits that enable you to easily swap out components like the trigger or grip for aftermarket options. This flexibility allows for future modifications without needing to buy an entirely new kit.
By planning for customization early, you can ensure your build remains adaptable to your evolving needs and preferences.
7. Read Customer Reviews
Before finalizing your purchase, take the time to read customer reviews. Reviews can provide valuable insight into the quality, performance, and reliability of the lower parts kit you’re considering.
- User Experiences: Look for comments on the assembly process, any initial issues, and overall satisfaction with the product. This feedback will help inform your decision-making and set realistic expectations.
Pay attention to both positive and negative reviews to get a balanced perspective.
8. Shop from Reputable Vendors
Finally, always purchase your AR-15 lower parts kit from trustworthy retailers. Online reviews and recommendations can guide you to reputable vendors with a history of excellent customer service and dependable shipping practices.
- Warranty and Return Policy: Before making a purchase, check the vendor’s warranty and return policy. A good warranty demonstrates the manufacturer’s confidence in their product and provides peace of mind.
By purchasing from a reputable vendor, you can ensure you’ll receive quality parts and reliable customer service if any issues arise.
