Our .338 ARC Assembled Upper isn’t just a parts kit—it’s a purpose-driven build crafted for reliability and accuracy. From receiver truing and barrel bedding to full live-fire testing, we go far beyond basic assembly. You get a tuned, verified upper built with name-brand components that won’t fail when it counts.
We use quality components from brands like Faxon and Aero Precision — not generic or untested parts. But the real difference is in the assembly:
Receiver truing
Mil-Spec torqueing
Headspace verification
Barrel bedding
Full test fire
Cheaper builds often skip these steps, which can lead to malfunctions, poor accuracy, or short service life.
Is this a true subsonic/supersonic setup?
Yes. The .338 ARC is built for both subsonic and supersonic loads. Our adjustable gas system and properly matched buffer setup ensure reliable cycling across loads—especially with the 307gr SUB-X and 175gr HP ammo. You won’t be chasing tuning issues like you might with cut corners.
Why is this considered “mid-tier”?
We deliver high-end build practices and quality components at a price that avoids full custom-rifle territory. It's built to perform, last, and upgrade easily—without the unnecessary cost of boutique builds or the risk of budget compromises.
