The Best AR15 Upper Receivers
The AR-15 has become one of the most popular firearms among American gun owners and for good reason. Due to its lightweight frame, high level of accuracy and versatility, the weapons system is a testament how innovation can transform an older design. For years now, firearms accessory manufacturers have been turning out various parts for the AR-15. While many still prefer to buy pre-built firearms, many others enjoy shopping around for the coolest and best parts on the market and create something special and tailored for them. One of the fundamental elements of the build starts with an upper receiver.
AR-15 Upper Receivers
When it comes to buying an AR-15 upper receiver, there are a number of options one can take. First, you have to decide whether or not you want to go with a forged option of billet. Forged receivers are stronger pound for pound compared to billet ones, but they lack some of the finer details and aesthetics that some people like to have. The other option, at least when it comes to our list, is whether or not you want just an upper receiver by itself or one that comes with a barrel, gas block and gas tube. For companies like Bravo Company USA, some of their prebuilt uppers do come with a rail system. So all you have to do is get a bolt carrier group and charging handle and you’d be good to go. This is sometimes the most cost-effective option to go with because it makes the assembly process easy.Best AR-15 Upper Receivers
