The AR platform has been tried and tested and is one of the world's most ergonomic and easy-to-use firearm platforms. Though the AR-15 is a very capable rifle, its caliber, 5.56 NATO, leaves more to be desired. It is ideal for self-defense, competition shooting, and many other applications. However, if you want to use your AR to hunt big game or shoot long-range, you will need a bigger caliber, and a complete .308 AR-10 upper is an excellent option. In fact, the AR-15's predecessor and inspiration was the AR-10, which was chambered in .308.
The Benefits of Using a Complete AR-10 Upper Receiver Assembly
A .308 AR offers many advantages. They carry more ammo, offer better control, and are modular, allowing you to mount many AR-15 accessories. However, these are the advantages of the AR platform in general. The .308 caliber itself has better stopping power than the 5.56; it’s more accurate because it’s less affected by the wind; and it has a better effective range because it has almost double the kinetic energy of a 5.56!
DPMS Style (LR-308)
DPMS Panther Arms developed a standard for AR-10 rifles and named its rifle the LR-308. This DPMS-style caught on in the market much more than the Armalite pattern, and most AR-10s or .308 ARs you will see at the range are DPMS-pattern rifles.
You can also easily find compatible parts for this complete .308 upper at virtually any halfway decent sporting goods store in the US.
Alternative (6.5 Creedmoor)
If you want an alternative to the .308, the 6.5 Creedmoor is an excellent option. The ballistics of both calibers are quite similar, and both hold a comparable trajectory up to 300 yards. In general, the 6.5 Creedmoor fires a smaller projectile and has a better ballistic coefficient.
