The modern patrol rifle needs to balance rugged reliability with straightforward serviceability. For operators and serious enthusiasts who prefer a proven, no-frills AR-platform built to mil-spec standards, the GEISSELE AUTOMATICS BORDER PATROL delivers a workhorse design that focuses on durability, alignment, and repeatable function.

GEISSELE AUTOMATICS BORDER PATROL

The Border Patrol is offered in multiple barrel lengths—11.5″, 14.5″, 16″, and 18″—with corresponding carbine, mid, and rifle-length gas systems. Its 14.5″ P&W barrel option with 5.56 NATO chambering is ideal for users who need a balance of maneuverability and terminal velocity. The rifle’s gas tube is retained with a pin and the gas block is secured with both a pin and two set-screws, ensuring the gas system remains precisely aligned under sustained use. Shop this product

Build and Materials

Geissele anodized Super Duty upper and lower receivers are forged from 7075 T6 aluminum for strength without excess weight. The barrels and gas systems use precipitation-hardened 17-4 stainless steel where specified, improving longevity in corrosive environments. Stainless-steel take-down pins, a posi-lock safety, Ultra Duty magazine release, and the Super Duty trigger guard round out the hard-wearing controls.

Rail, Controls, and Trigger

The skeletonized 20 Super Modular Rail reduces weight and includes M-LOK slots at 3, 6, and 9 o’clock, plus a keyed mating system to prevent handguard twist—critical for repeatable zero with optics and suppressors. Geissele’s Government Charging Handle features articulating levers for ambidextrous operation. The ALG Defense Advanced Combat Trigger (ACT) is treated with nickel-boron and nickel-teflon coatings for smoother pull and corrosion resistance while maintaining mil-spec function.

Buffer and Reliability Enhancements

A braided-wire buffer spring provides roughly 15% more pressure on the buffer, driving the bolt carrier group harder to improve extraction and cycling when the rifle is dirty or loaded to capacity—practical for extended field use.

At a listed price of $1,637.99, the GEISSELE AUTOMATICS BORDER PATROL is positioned for professionals and enthusiasts who prioritize service-grade construction and long-term reliability.
