Overview

The Primary Arms SLx MD21 is an advanced 1x micro dot sight featuring a 21mm objective lens and a crisp 2 MOA red dot reticle in a matte black anodized finish. Built on the widely supported Aimpoint Micro footprint, it mounts easily to standard Picatinny rails.

Autolive motion-sensing technology automatically powers the unit down when idle and instantly reactivates it upon movement. Weighing just 5 ounces, the compact optic is constructed for durability in demanding tactical and field environments.

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.
