F1 Firearms 223 Wylde 7.5″ Upper / Pistol Build Kit
Price: $657.68
This isn’t a range toy. This is a serious, compact build kit chambered in 223 Wylde. That means you can safely and accurately run both .223 Rem and 5.56 NATO with better precision than a standard 5.56 chamber. The 7.5-inch barrel keeps it ultra-maneuverable for tight spaces or vehicle use.
It’s built right. The semi-auto action is reliable, and it comes with a standard mil-spec grip. You get a 30-round magazine capacity. We left the sights off intentionally—this lets you choose your own optic or iron sights to match your mission. Pair this upper with your favorite lower receiver and you’ve got a potent, no-nonsense firearm ready for work.
From F1 Firearms, known for solid performance. If you need a compact, versatile AR platform that handles any .223/5.56 ammo you feed it, this is the kit.
