AR Platform Builds

Purpose-built AR-15 and AR-10 platforms for any application.

// The Promise

Every Component Intentional. Every Function Verified.

// Overview

We build AR platforms from scratch using components we trust, not what's cheapest. Whether you need a duty carbine, a competition gun, a suppressor host, or a precision DMR-style upper, we spec the build around your application and assemble it to a standard that most production rifles never reach.

// The Process

How We Build It

STEP 01 //01

Defining the Mission

AR platform builds vary wildly depending on what they're for. We start by understanding your application, duty, competition, home defense, hunting, or suppressor host, so we build the right gun, not just a good one.

STEP 02 //02

Component Selection

Barrel profile, gas length, handguard, BCG, trigger, each is selected based on your mission. We work with BCM, Rainier Arms, Geissele, LaRue, and other brands that hold up under real use.

STEP 03 //03

Assembly & Gas Tuning

The upper and lower are assembled to spec. Gas systems are tuned for reliability across a range of ammunition, critical for suppressed configurations or competition use where round counts are high.

STEP 04 //04

Function Check & Test Fire

Every build is function-checked and test-fired before delivery. Suppressor-ready builds are verified with your suppressor in place if possible.

// Common Questions

FAQ

Do you build AR pistols or SBRs?

Yes. We build pistol-configuration ARs and can assist with the NFA process for SBR conversions if you're in a form-4 state.

Can you work on my existing rifle?

Absolutely. Trigger upgrades, handguard swaps, gas system work, and Cerakote are all available as standalone services.

What's your preferred barrel for a duty build?

It depends on length and application, but we frequently spec BCM, Daniel Defense, and Ballistic Advantage barrels for duty configurations.
