The AR-15 is a semi-automatic assault rifle in Stranded on Earth: The First Strike. It can spawn with you for free if you've purchased the 'Enhanced Spawn' Gamepass, otherwise it is only obtained through the shop or from the Mystery Box.
The AR-15 in Stranded on Earth: The First Strike is based on the Colt AR-15, which was manufactured by Colt's Manufacturing LLC. Variants of the AR-15 are used worldwide, and the design has been widely used due to it's reliability and ease of use, spawning much newer designs that improve on the original design. It is chambered for 5.56x45mm NATO, 7.62x39mm, and 9mm Parabellum ammunition, despite the in-game description stating that it is chambered in only 5.56mm and .223.
In Stranded on Earth: The First Strike lore, the AR-15 was widely used by both police and military forces before the apocalypse, and as a result was also mass produced along with the P226, but is still a lesser common sight due to most of the models being taken or broken over time. A large stock of them was stored in the armory of Fort Lazarius, allowing Pegasus to gain a massive supply of them in their efforts to push back the undead.

- The AR-15 is most likely a Colt AR-15 due to various features, most notably that Colt's model is only semi-automatic, while many others are not just semi-automatic or simply fully automatic.
