The Cross Armory Rear Sight Dovetail RMSc Mount Adapter is a low-profile mounting solution for Glock pistols, replacing the factory rear sight dovetail. It is precision-machined from 17-4 stainless steel and features a durable black nitride finish. The unit includes an integrated bright green fiber-optic co-witness front sight. This adapter is compatible with most non-MOS Glock models (including the 17, 19, 19X, 20, 21, 22, 23, 24, 26, 27, 29, 30, 30SF, 34, 36, 42, 43, 43X, 45, and 48) but does not fit the Glock 44. Optic is not included.
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.
