The Colt OEM Series delivers customizable AR-15 rifles designed as foundational platforms for personalized builds. The Colt OEM1 offers a stripped-down configuration with a 16.1-inch barrel and a flat-top upper receiver, allowing users to select their own stock, handguard, and grip. This model comes chambered in 5.56x45mm NATO / .223 Remington and includes a standard 30-round magazine, making it ideal for those who wish to tailor every component to their specific needs. The Colt OEM2 enhances the OEM1 by incorporating a basic handguard and a collapsible stock, providing a more complete rifle while still allowing for significant customization. Both models are distinguished by their focus on providing a versatile, high-quality base without pre-installed accessories, unlike other Colt rifles that come fully equipped. This approach caters to shooters who prefer to build their rifle with preferred aftermarket parts, ensuring the final product meets their exact specifications and preferences.
