Product Details
This Colt upper receiver pairs a compact 11.5-inch barrel with the proven reliability Colt's known for, making it a solid choice if you're building or upgrading an AR-15 or M4 setup. The matte black finish won't glare in bright light, and the shorter barrel gives you better handling in tight spaces without sacrificing too much velocity in 5.56 NATO. It's the kind of dependable piece that works whether you're at the range learning the fundamentals or handling real-world situations.
