The TacFire SSRK300LPK is a 300 Blackout AR build kit designed for shooters who want to assemble a capable, quiet rifle without buying parts piecemeal.

TacFire's reputation for no-nonsense, affordable AR parts makes this kit a solid entry point for DIY builders and experienced gunsmiths alike.

Built around black nitride-finished steel and aluminum components, the kit emphasizes durability and corrosion resistance. The 1/2"-28 tpi muzzle threads are the modern standard for 300 Blackout suppressors and brakes, so you'll have no trouble adding the accessories you want.

As a Sports South exclusive, this configuration combines TacFire's value pricing with components selected for the 300 Blackout platform. You'll need to verify you have all required tools, jigs, and gunsmithing experience (or access to a qualified builder) before starting your project—an AR build kit typically requires some assembly knowledge or professional help to complete safely and reliably.
