Answer: The KAC SR-15 Mod2 E3 Upper Receiver Group features a 14.5" barrel. This length provides a balance of accuracy and maneuverability, making it suitable for a variety of shooting scenarios. Like the M4 Carbine, 14.5" is a popular common barrel length. For use in the civilian world, a 14.5" barrel on a standard rifle lower receiver becomes a short barreled rifle, subject to NFA laws and registration. Many customers ask us to pin and weld a flash hider permanently to the barrel to create a 16" (non-NFA) rifle.
Answer: The KAC SR-15 Mod2 E3 Upper Receiver Group weighs 4.0 lbs. This lightweight design makes it easy to handle and operate, enhancing user comfort and control.
Answer: The KAC SR-15 Mod2 E3 Upper Receiver Group is designed for the AR15 SR-15 platform. It's a versatile component that can enhance the performance of your existing firearm setup.

Answer: Certainly, Knights stands out as a premium brand in the military correct space. Our customers tend to look for high performing military grade upper receivers. Some other brands that are often compared with Knights include: LMT Defense, Geissele, Noveske, LaRue and some custom military correct builds from Potomac Armory.

Note: Charlie's receives these rifle uppers as both independent parts and also as take-offs from brand-new factory KAC rifles. There is no difference. All rifles ship with the same parts, and the same warranty.
Note: The factory 3 prong flash hider can be pinned to bring the upper to a non-NFA 16" barrel length. We can also swap the flash hider for other muzzle devices before shipping - ask us. We can also pin and weld, although the shop effort is a little more due to how hard it is to remove the muzzle device.
