Product Details
This is the upper receiver assembly that pairs with a lower to make a complete rifle - think of it as the "top half" that does the actual shooting. It's got an 11.5-inch barrel, which keeps things compact without sacrificing reliability, and it's already outfitted with fixed front and rear sights so you're not buying extras. The 223 Remington/5.56 NATO chambering is the most common rifle round out there, which means ammunition is easy to find and affordable. This is a solid, no-nonsense choice if you're building your first AR or adding to what you already have.
