Overview

The San Tan Tactical STT-15 Pillar upper receiver is a precision-engineered AR-15 component machined from a single billet of 7075-T651 aerospace-grade aluminum. Designed for those seeking a lightweight yet robust build, it features a proprietary truss-pocket geometry that enhances structural rigidity while reducing overall mass. The upper receiver weighs approximately 0.88 lbs and is finished with a Mil-Spec Type III Class II hard-coat anodized black coating. The receiver is compatible with standard AR-15 components, including rail systems and charging handles. It includes M4 feed ramps, a shell deflector, and a Mil-spec ejection port cover.

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.
