AR10 Upper Receiver
The Gorilla Machining AR-10 20" Upper Receiver in 4150 CMVS .308 Winchester with a 1/10 twist rate and 15" M-LOK handguard is a remarkable choice for those looking to build a highly capable, long-range, precision-oriented AR-10 rifle. This unassembled upper receiver provides customization flexibility and is manufactured with precision, durability, and performance in mind, making it ideal for both seasoned builders and first-time rifle enthusiasts.
The bolt carrier group (BCG) is one of the most important components for reliability and smooth cycling. A high-quality, .308-compatible BCG will ensure smooth feeding and extraction, contributing to the rifle’s overall accuracy and dependability. The right muzzle device can reduce recoil and muzzle rise, making follow-up shots quicker and more accurate. For a precision rifle, a muzzle brake or compensator can help manage the .308's recoil, providing a more comfortable shooting experience.
The Gorilla Machining AR-10 20" Upper Receiver in 4150 CMVS .308 Winchester, with a 1/10 twist rate and 15" M-LOK handguard, is a premium choice for builders seeking a reliable and customizable upper. Its design ensures accuracy, durability, and adaptability, making it suitable for precision shooting and tactical applications alike.
Building an AR-10 using this unassembled upper receiver allows you to create a rifle tailored to your exact specifications. By selecting compatible, high-quality components and following best practices during assembly, you can optimize your AR-10 for any shooting environment. Whether you're aiming for long-range accuracy or hunting, this Gorilla Machining upper receiver provides a solid foundation for a powerful and customizable rifle.
