Building your own AR-15 can be a rewarding experience, offering a level of customization unavailable with pre-assembled rifles. However, for those new to the process or seeking a more streamlined approach, AR-15 complete build kits provide an excellent alternative. These kits include all the necessary components, significantly simplifying the build process while still allowing for some degree of personalization. This guide will delve into the world of AR-15 complete build kits, helping you understand what to look for, what to consider, and how to make an informed purchase.
Understanding AR-15 Complete Build Kits
An AR-15 complete build kit typically includes all the parts needed to assemble a functional rifle, excluding only the necessary tools. This usually comprises:
- Upper Receiver: Houses the barrel, bolt carrier group, and charging handle.
- Lower Receiver: The firearm's serialized component, containing the trigger group, pistol grip, and buffer tube. Note: The lower receiver is often the only part that needs to be purchased separately in some states due to legal restrictions.
- Bolt Carrier Group (BCG): A critical component responsible for cycling the ammunition.
- Barrel: The heart of the rifle, determining accuracy and caliber.
- Charging Handle: Used to manually cycle the bolt.
- Handguard/Rail System: Provides a mounting surface for accessories.
- Pistol Grip: Provides a comfortable grip for the shooter.
- Buffer Tube and Stock: Houses the buffer spring and provides a shoulder rest.
- Trigger Group: The mechanism that fires the rifle.
Some kits may also include additional components such as sights, magazines, and even optics. The level of completeness varies significantly between manufacturers and price points.
Choosing the Right AR-15 Complete Build Kit
Selecting the right kit requires careful consideration of several factors:
1. Budget:
Kits range considerably in price, from budget-friendly options to high-end, feature-rich packages. Determine your budget before you start browsing to avoid buyer's remorse.
2. Intended Use:
The intended use of your AR-15 will dictate the necessary components and features. A home defense rifle will have different requirements than a long-range precision rifle. Consider factors like barrel length, handguard type, and optic choices.
3. Brand Reputation:
Research manufacturers known for producing high-quality, reliable components. Reading reviews from other users can help you assess the reputation and performance of different brands.
4. Components Quality:
Pay attention to the quality of individual components within the kit. Look for durable materials and precise manufacturing. Low-quality components can compromise the rifle's reliability and performance.
5. Caliber:
AR-15 platforms are available in various calibers, most commonly 5.56 NATO/.223 Remington. Choose a caliber that aligns with your intended use and ammunition availability.
Beyond the Kit: Tools and Considerations
While complete build kits simplify the assembly process, you'll still need the right tools. Essential tools typically include a torque wrench, armorer's wrench, and a punch set. It’s crucial to consult the manufacturer’s instructions and follow safety guidelines meticulously. Remember that even with a complete kit, proper assembly and functionality depend on careful attention to detail.
Conclusion
AR-15 complete build kits offer a convenient and relatively affordable way to assemble your own rifle. However, thorough research and careful consideration of factors like budget, intended use, and component quality are crucial for selecting the right kit and ensuring a successful build. Remember to prioritize safety throughout the entire process, and consult relevant resources and guidelines before handling firearms.
