About the options:
Barrels available in this kit are 16" length, with a 1:8 twist rate. Generally speaking, the twist rate is a common factor when considering the primary purpose of the rifle, and which ammo you will shoot as it correlates to bullet weight. A 1:8 twist rate is regarded as the best "general purpose" twist rate for a multitude of sporting purposes because it has been shown to accurately shoot bullets in the wide range of 50-80 grains.
.223 Wylde or 5.56mm NATO?
A common question, with a simple answer. Both the barrel options included in this complete AR-15 kit will safely shoot 5.56mm NATO or .223 Remington ammunition. For some, it's a matter of preference. However, the .223 Wylde barrel will shoot .223 Remington with better accuracy than a barrel chambered in 5.56mm NATO, but can also withstand the pressure load of 5.56mm NATO. The popularity of .223 Wylde chambered barrels as somewhat of a "hybrid" chamber has grown in the past years, bringing the price point of the .223 Wylde down to that of the common 5.56mm NATO barrel.
Stainless or Parkerized?
Again, this is much a matter of preference and the general look desired. In this complete AR-15 80% build kit, both the Parkerized high-carbon steel and 416R stainless steel barrels will provide years of accurate performance. Parkerized barrels have a metal finishing process applied to provide a long lasting and durable flat black surface finish. Stainless Steel barrels are constructed of 416R Stainless Steel and provide the satin silver look that many enthusiasts prefer.
A2 Style Flash Hider or Compact Muzzle Brake? While mostly a matter of looks or preference, some states have outlawed A2 Style Flash Hiders or consider them to be "evil features", contributing toward what may or may not be considered an "assault rifle" under the definition of state law. Be sure to read and understand your local laws. Aside from the legality, there are benefits in looks and performance when choosing a Compact Muzzle Brake. Muzzle brakes, besides looking cool, divert the gases exiting the barrel in such a way that reduces recoil and muzzle rise, and can improve follow-up shot accuracy.
When it comes to choosing a handguard for your new rifle, there is a delicate balance of form and function. For starters, our M4 Style Handguard with exposed gas block is lightweight, budget-friendly, and perfect for those adding a receiver-top optic. Our lightweight M-LOK free-float handguard designs are available in 12" and 15" lengths. While mostly a matter of personal preference, these attractive handguard styles can offer functional performance for all of your shooting needs.
