Limited Series: March 2024 - 50 Shades of FDE

In stock


Our Limited Series M4A1 RIII FSP is a unique combination of old-school cool meets cutting-edge design. It’s the only rifle ever produced by Daniel Defense with a RIS III FSP Upper that features an F-Marked fixed front sight, MBUS Pro LR adjustable rear sight, and our cutting-edge RIS III Rail with popular M-LOK attachment and an uninterrupted Picatinny upper rail platform. This rifle package comes with an old-school Trijicon TA31F ACOG 4x32 BAC riflescope and a whole lot of other extras, including a newly released Modlite 18350 Weapon-Mounted Light with ModButton Lite 4.5” cable and a Unity Gascap USB Tailcap for surgical control. We also upgraded the charging handle with a cool PRI M84 Gas Buster with Combat Latch. Throw in a Geissele SSA Trigger and B5 Aluminum Trigger Guard, B5 Sopmod Stock, Type 23 Pistol Grip and B5 Plug, and a few other upgrades listed below, and you’ve got an M4A1 dressed in attractive Flat Dark Earth and Coyote Brown unlike any ever before produced.  

But this rifle is still 100% M4A1, one of our top-performing, best-selling rifles. Like all Limited Series rifles, the M4A1 RIII FSP comes with a Certificate of Authenticity and Commemorative Challenge Coin to prove you are one of a handful of owners of this very rare, very collectible rifle.
