Overview

The Lantac M-Spec Bolt Carrier Group is precision-machined to strict military specifications for AR-15 platforms chambered in 5.56x45mm. The full-auto style carrier is manufactured from 8620 steel, case-hardened, and ground to exact internal dimensions with a durable nickel boron finish that enhances corrosion resistance, lubricity, and overall performance. The bolt is machined from Carpenter 158 steel, shot-peened, and hard-turned. Additionally, each assembly is fitted with a precision-machined 17-4PH stainless steel CP-R360 domed cam pin, which is hand-polished and hardened to H900 to reduce friction and wear inside the upper receiver.

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.
