Buyer’s Guide

The AR-10 platform has become increasingly popular among rifle enthusiasts and competitors. Understanding the key components and considerations will help you select the right parts for your build.

Recoil System

Effective recoil management is crucial for maintaining control during rapid fire. Consider the barrel’s weight and length, as heavier barrels reduce felt recoil. Additionally, evaluate the bolt carrier group’s design; some incorporate proprietary systems for enhanced performance.

Sight and Optics

For target shooting and precision work, variable-power optics between 2.5x and 10x offer versatility. Consider features like windage and elevation adjustments, parallax correction, and water resistance. When selecting a sight, ensure it matches your intended usage and environmental conditions.

Fire Control Group

The fire control group (FCG) affects trigger pull weight, reset distance, and take-up. Premium FCGs often offer adjustable triggers with factory-set options between 3.5 and 4.5 pounds. Custom FCGs can further tune performance, but require proper setup to maintain safety standards.

Barrel Profile

Barrel weight, length, and profile significantly impact the rifle’s handling characteristics. Heavier barrels reduce felt recoil but add weight. Longer barrels increase muzzle velocity but reduce cycling speed. Common profiles include standard (20” with handguard), mid-length (16” with handguard), and carbine (16” without handguard).
