When it comes to firearms, the AR-15 platform has gained immense popularity due to its versatility, modularity, and reliability. One of the best ways to customize your AR-15 to your exact preferences is by building it yourself. Durkin Tactical offers an AR-15 Rifle Build Kit that provides you with all the necessary components, except the stripped lower receiver, to create a high-quality 16” AR-15. In this blog post, we will explore the features and benefits of this build kit, helping you understand why it is an excellent option for firearms enthusiasts and first-time builders alike.

Included Features of the AR-15 Rifle Build Kit:

16" 5.56/.223 Wylde Barrel

The kit includes a 16” barrel, available in either black nitride or stainless steel, providing durability and corrosion resistance. Please note that the twist rate may vary, ensuring compatibility with a wide range of ammunition choices.

10"-15" Free-Float Handguard

The handguard included in the kit, whether keymod or mlok, depending on availability, offers a free-floating design. This feature ensures improved accuracy by minimizing barrel interference, allowing for the attachment of various accessories such as grips, lights, and lasers.

A2 Flash Hider

The A2 flash hider effectively reduces muzzle flash and redirects gases to mitigate recoil, providing a more comfortable shooting experience.

Complete Mil-spec Stock Kit

This build kit comes with a complete mil-spec stock kit, including a stock, endplate, buffer tube, buffer, buffer spring, and a castle nut. The mil-spec components ensure reliability, compatibility, and ease of customization.

Nitride BCG

The nitride-coated bolt carrier group (BCG) enhances durability, reduces friction, and makes cleaning easier. This critical component ensures smooth and reliable cycling of the firearm.

Stripped or Upgraded Billet Upper Receiver

Depending on availability, the build kit provides either a stripped or an upgraded billet upper receiver. These receivers offer exceptional strength, improved aesthetics, and compatibility with a wide range of aftermarket accessories.

Forward Assist and/or Dust Cover

Depending on the Upper chosen, this kit could include a forward assist, allowing you to manually push the bolt carrier group forward if needed. Additionally, a dust cover is provided that helps prevent debris from entering the action, ensuring reliable operation in various environments.

Steel Gas Block and Stainless Gas Tube

The steel gas block and stainless gas tube facilitate the proper cycling of the firearm by regulating gas flow from the barrel to the BCG. These components contribute to the AR-15’s reliability and longevity.

Standard Charging Handle

The build kit includes a standard charging handle, allowing for easy manipulation of the bolt carrier group during charging and clearing malfunctions.

Complete Lower Parts Kit

With a complete lower parts kit included, you have all the necessary components to assemble the lower receiver, ensuring the foundational integrity of your AR-15 build.

Now, the big question: Is it better to buy or build an AR? Well, it depends on your preferences. Buying a fully-assembled AR-15 offers convenience, but building your own has its advantages.

We recommend utilizing online resources such as YouTube guides, which offer step-by-step instructions and visual demonstrations to help you through the assembly process. Additionally, we offer various tools and accessories like build mats, AR wrenches, vice blocks, and punch sets to make the building process easier and more efficient.

Last but not least, do you need an FFL (Federal Firearms License) to buy a build kit? The answer is no. Purchasing our AR-15 rifle kits does not require an FFL. The kits arrive disassembled, and even when assembled, you would still need a serialized stripped lower receiver to have a fully functioning firearm.
