Unlock Your Custom AR-15 Build: The TacFire .300 Blackout Rifle Kit

Are you an aspiring gunsmith, a seasoned firearms enthusiast, or someone looking to finally build your very own AR-15 from the ground up? Perhaps you’re seeking a reliable, high-performance platform chambered in the versatile .300 Blackout caliber for specific shooting applications, from hunting to home defense or simply enjoying time at the range.

This is where the TacFire SSRK300LPK AR Build Kit Rifle emerges as an exceptional solution, providing a comprehensive, high-quality foundation for your next project.

Forget the hassle of sourcing individual parts and wondering about compatibility. The TacFire SSRK300LPK kit, designed for the popular AR-Platform, eliminates guesswork by packaging nearly all the essential components you need (excluding the stripped lower receiver itself, which is typically purchased separately due to federal regulations) into one convenient package. This kit is specifically engineered for builders who demand performance, durability, and the potent capabilities of the .300 AAC Blackout cartridge. It's an ideal choice for anyone asking, "What are the best components for a .300 Blackout AR build?" or "How can I easily assemble a high-quality AR-15?"

Why Choose the .300 Blackout Caliber?

The .300 Blackout (300 BLK) has rapidly gained popularity among shooters for its incredible versatility. Developed to offer effective performance in short barrels and suppressors, it shines in scenarios where both subsonic and supersonic capabilities are desired. With a simple barrel and magazine swap, a standard AR-15 platform can be transformed into a .300 Blackout rifle, utilizing many of the same core components as a 5.56/.223 build. This caliber is celebrated for its:

• Versatility: Excellent for suppressed shooting with heavy subsonic bullets, and capable of significant energy transfer with lighter supersonic loads for hunting or self-defense.
• Performance in Short Barrels: Optimized to achieve impressive ballistics even from compact barrel lengths, making it ideal for tactical applications or tighter environments.
• Shared Components: Leverages the existing AR-15 platform, reducing the need for completely new setups for those already invested in the AR system.

The TacFire SSRK300LPK capitalizes on these advantages, providing a purpose-built foundation for this dynamic cartridge.

2. .308 5/8 x 24 TPI Spiral Fluted Flash Can with Crusher Washer

Designed to direct muzzle blast forward, away from the shooter and bystanders, a flash can is an excellent choice for shorter barrels or when shooting indoors. The spiral fluting not only looks distinctive but also aids in weight reduction. The included crusher washer ensures a secure and properly timed installation.

• Caliber Compatibility: Designed for .308 bore, ensuring proper clearance for .300 Blackout projectiles.
• Thread Pattern: 5/8" x 24 TPI, a standard for .30 caliber muzzle devices, allowing for easy interchangeability if desired.
• Function: Effectively redirects sound and concussive forces forward, enhancing the shooter's experience and reducing perceived muzzle flash.

3. AR15/.750 Micro/Low Profile Gas Block (Mil-Spec/Steel)

A crucial component in the direct impingement gas system, this low-profile gas block fits under most free-float handguards. Being Mil-Spec (Military Specification) ensures it meets rigorous standards for quality and performance.

• Diameter: .750 inch, matching the standard gas journal diameter for many AR-15 barrels.
• Profile: Low profile design allows it to tuck neatly under the handguard, contributing to a sleek and streamlined rifle.

• Mil-Spec: Indicates adherence to strict military standards for dimensions and material quality, ensuring reliable gas flow.

4. Pistol Length Gas Tube with Pin (Steel)

Paired with the pistol length barrel system, this gas tube efficiently directs gas from the barrel's gas port back to the bolt carrier group, cycling the action. Made from steel for longevity.

• Length: Pistol length, precisely matched to the 16" .300 Blackout barrel's gas port location for optimal cycling.
• Material: Steel for robust, high-temperature performance.
• Function: Essential for the semi-automatic operation of the rifle, ensuring proper gas regulation for reliable feeding and ejection.

5. Ultra Slim Clamp On MLOK Free Floating Handguard

The handguard is where ergonomics meet modularity. This ultra-slim, free-floating design offers a comfortable grip and prevents barrel deflection from pressure applied to the handguard, enhancing accuracy.

• Mounting System: MLOK (Modular Lock) slots provide a lightweight and robust interface for attaching accessories like lights, lasers, foregrips, and bipods.
• Free-Floating Design: Ensures that no pressure from your grip or accessories affects the barrel's harmonics, leading to improved precision.
• Profile: Ultra-slim for a comfortable and agile feel, reducing bulk and weight.
• Installation: Clamp-on design simplifies installation, ensuring a secure fit without specialized tools.

6. AR15 5.56/.223/.300AAC Stripped Billet Upper Receiver with M4 Feed Ramps

The upper receiver houses the barrel and bolt carrier group, playing a critical role in the rifle's function. This stripped billet upper is machined from a solid block of aluminum, offering superior strength and precision compared to forged alternatives.

• Compatibility: Designed for 5.56/.223 and .300AAC, ensuring seamless integration with the included .300 Blackout barrel.
• Construction: Billet aluminum provides enhanced structural integrity and a refined finish.
• M4 Feed Ramps: Essential for reliable feeding of ammunition, especially in high-volume shooting or under adverse conditions. These ramps guide cartridges smoothly into the chamber.
• Stripped: Allows the builder to choose their own forward assist and dust cover, providing a degree of customization.

7. AR15/.556 Mil-Spec Charging Handle (Aluminum w/ Steel Latch)

A fundamental component for cycling the action and clearing malfunctions, this Mil-Spec charging handle is built for durability.

• Material: Aluminum body for lightness, combined with a steel latch for resilience where it matters most.
• Mil-Spec: Guarantees compatibility and reliability with standard AR-15 components.

8. Dust Cover

Protects the internal components of the upper receiver from dirt, dust, and debris, especially crucial in adverse environments.

9. AR15 Forward Assist

Allows the shooter to manually push the bolt carrier group fully into battery, ensuring proper lock-up, particularly useful if a round doesn't seat completely.

10. AR15 Standard Receiver End Plate

Connects the buffer tube to the lower receiver, providing a stable mounting point for sling attachments.

11. Mil-Spec/Commercial Castle Nut (Steel)

Secures the buffer tube to the receiver extension, ensuring stability and proper alignment. Being steel, it offers robust strength. The kit accommodates both Mil-Spec and commercial buffer tubes.

12. AR15 Pistol Buffer Tube with Foam

Essential for housing the buffer and buffer spring, managing recoil, and cycling the action. The foam padding provides a comfortable cheek weld for pistol builds.

• Type: Pistol buffer tube, designed for AR pistol configurations, ensuring the overall length adheres to legal definitions for AR pistols.
• Material: Durable aluminum construction.
• Padding: Foam provides a comfortable contact point for stability during firing.
