Overview

The Proof Research AR-style rifle barrel is engineered for the 6mm ARC caliber on AR platforms. Built using a match-grade 416R stainless steel core that is double-stress relieved, the barrel is turned down to a reduced profile and wrapped in high-strength, aerospace-grade carbon fiber using a proprietary resin matrix. This carbon fiber wrap aids in heat dissipation and thermal transfer, delivering the durability and precision of a heavy match barrel at a significantly reduced weight. The barrel features a .750-inch gas journal diameter, threaded muzzle, and a 1:7.5 twist rate, providing a reliable and accurate foundation for precision rifle builds.

About DealsGunsAmmo (DGA)

A price and stock aggregator built for a market the incumbents stopped improving.

We compare listings across dozens of retailers and normalize everything to true cost-per-round — not sticker price, not case-size guesswork.

Who we are

DealsGunsAmmo (DGA) is an independent data provider tracking price and stock across the ammo, firearm, and parts market — giving buyers and the industry an outside, macro-level view of where the market actually stands.

What we’re building

A data-driven platform meant to be the go-to spot for purchasing decisions — comparing offers across vendors and tracking price history, so you can read the market as a whole, not just one listing at a time.

Who we serveNOW

Today, we help buyers on their purchasing journey with price alerts and a real look at where prices have actually been.

LaterNEXT

Down the road, we plan to sell that same market data back to vendors — inventory demand, customer interest and sentiment, and competitive pricing.
