Design and Construction

The Border Patrol uses precipitation-hardened 17-4 stainless steel for its barrels, ensuring longevity and consistent service life across all offered lengths. The gas tube is secured with a retaining pin and the gas block uses both a pin and two set-screws—dual attachment that locks alignment in place under hard use. Weight is reduced with a skeletonized 20 Super Modular Rail featuring M-LOK slots at the 3, 6, and 9 o’clock positions and a keyed mating system to prevent handguard twist during demanding patterns of fire.

Controls, Hardware, and Durability

Receivers are Geissele’s Super Duty upper and lower forged from 7075 T6 aluminum and finished with hard-coat anodizing. Hardened stainless take-down pins, a posi-lock safety, Ultra Duty magazine release, and a Super Duty trigger guard are included for duty-grade reliability.

Reliability Under Stress

Ambidextrous operation is supported by Geissele’s Government Charging Handle with articulating levers. The braided wire buffer spring increases buffer pressure by about 15%, driving the bolt carrier group more positively—especially helpful when the rifle is dirty or when running full magazines. The rifle ships with ALG Defense’s Advanced Combat Trigger, treated with nickel-boron on the trigger and nickel-teflon on hammer and disconnector for smoother pulls and improved corrosion resistance.

Chambered in 5.56 NATO, this rifle fits patrol, range duty, and training roles where common ammunition, controllable recoil, and logistical compatibility matter. The combination of hardened barrels, keyed handguard, ambidextrous controls, and treated trigger components make the Border Patrol a practical, reliable choice.
