Overview

The Proof Research AR-10 Barrel is precision-machined in-house from double-stress relieved 416R stainless steel, making it well-suited for match-grade rifle builds. This 22-inch heavy contour barrel features a 1:8" twist rate, 5/8x24 threading, a .875 journal, and utilizes Proof’s Caliber Matched Gas System (CAMGAS). The CAMGAS design is engineered specifically for 6.5 Creedmoor and .260 caliber AR-variant platforms to alleviate excessive bore pressure by relocating the gas port. This tuned gas system yields a smoother recoil impulse, reliable case extraction, and consistent accuracy without requiring makeshift adjustments like modified buffer springs or weights.

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.
