Limited Series: August 2023 - M4A1 RIII™ - HOT SUMMER NIGHTS

In stock



The M4A1 RIII - Hot Summer Nights may be our seventh in the Limited Series, but it comes with a lot of firsts—it’s also the lowest quantity we’ve ever produced. 

The fully accessorized Hot Summer Nights comes with a Gen III Green Phosphorous PVS-14A Night Vision Monocular, including a carrying case and skullcrusher mount. Plus, it features a black EOTech EXPS-3 on an FDE Unity Tactical FAST Optic Riser and an FDE Steiner DBAL i2 (IR and Red Laser) with an FDE Unity Tactical Axon Switch.

We took our best-selling M4A1 RIII carbine with a fully ambidextrous lower and robust 12.5” RIS III rail with M-LOK attachment and customized and accessorized it to be like no other firearm in the world. The rifle is cerakoted in Deep Woods Green—a first for any RIII rifle or RIS III rail—and outfitted with black Magpul furniture. The trigger has been upgraded to a Geissele SSA, and the rifle features a Radian Raptor-LT Charging Handle and Radian Talon Safety (L-S configuration). Other upgrades include a SureFire 4-Prong Flash Hider, which only recently hit the civilian market and is tough to acquire, an FDE Ferro Concepts Slingster, a Railscales RSB/M vertical grip in Terra Bronze, and a set of Railscales IR Defeating Grip Panels in Terra Bronze, which have also never before been offered to civilians.

This Limited Series rifle offers unmatched performance in a never-before-seen package with the upgrades and accessories to meet most any mission requirements. All backed by a Certificate of Authenticity and Daniel’s 100% Satisfaction Guarantee.
