Details:
The 5.56 is a competent round for self-defense and even hunting. However, if you want to make longer shots and hunt big game, you need a battle rifle round, like the .308 Winchester.
The AR is an excellent platform for .308 cartridges, and if you are thinking about building a .308-chambered AR-15, you'll need a high-quality barrel and upper assembly. The Aero Precision Enhanced 16" .308 CMV M5E1 Complete Upper Assembly is an excellent option that includes the parts to help you build an accurate, reliable, and smooth-shooting rifle.
A High-Quality Barrel
The Aero Precision M5E1 Enhanced Upper Receiver Assembly includes a high-quality 16-inch CMV barrel chambered for .308 Winchester. CMV is a type of Mil-Spec steel developed for military-issued M4s. This AR-15 complete upper is pretty similar to 4150 steel and contains Vanadium, which significantly increases the barrel's strength, hardness, and high-temperature stability.
Moreover, the barrel has a QPQ finish on both the inside and outside to make it extremely corrosion-resistant. The barrel has also been HP/MPI tested to ensure there are no minor fractures, so you can be confident it will last for a very long time.
The barrel has a 1 in 10 twist rifling and is threaded too. It comes equipped with an A2 flash hider.
A Smooth and Reliable Gas System
When it comes to the shooting experience of an AR 308, the gas system plays a very important role. In this upper parts assembly, you will get a mid-length gas system, which is known to be a lot more comfortable to shoot than a carbine-length gas system. Though that might not be as important to some people with a 5.56 AR-15, .308 is a hefty round and carries a lot of energy. So, the recoil is also stronger, and a mid-length gas system can help mitigate it to some extent.
Lightweight Upper and Handguard
With any rifle, you want it to be light and maneuverable. Well, the Aero Precision M5E1 Complete Upper is precision-machined for lightweight durability. To ensure reliable feeding of the .308 round, this upper also has M4 feed ramps and features a forward assist.
You also get a really cool, lightweight full-length handguard with a one-piece free-floating design. It has a full-length top rail for mounting scopes and sights, and M-LOK slots on both sides as well. The handguard has quick disconnect sling sockets at the 3, 6, and 9 o'clock positions.
Final Thoughts:
If you are looking for a modern, lightweight .308-chambered rifle with good long-range capabilities, a .308-chambered AR is an excellent option. They are affordable, easy to use, have incredible aftermarket support, and are quite fun to shoot. This M5E1 Enhanced Upper Receiver Assembly is perfect for anyone building a .308 AR-15.
