Description
The ALG Defense El Corto is Geissele Automatics' answer to the demand for a Mil-Spec quality short-barreled AR pistol at an accessible price point — a platform where both the upper and lower receivers are built from the ground up using the best possible quality materials and manufacturing techniques without the cost premiums that Geissele's top-tier Super Duty platform carries. The El Corto receiver set starts with domestically sourced 7075 aluminum billets that are heat-treated at around 1,000 degrees Fahrenheit before being hammered into rough shape using a 1,100-ton forge press — the same forging process that produces the strongest, most dimensionally consistent aluminum receiver construction available. Both upper and lower receivers are then precision machined on CNC horizontal machining centers and finished with a Mil-Spec Type 3 black anodized hardcoat that provides the corrosion resistance and surface hardness that serious field use demands. The ALG El Corto premium 11.5-inch barrel is button rifled and hard chrome plated for optimal corrosion and wear resistance — a barrel construction specification that gives the El Corto an exceptionally long service life and maintains accuracy through thousands of rounds even at a high rate of fire. The barrel is topped with an A2 flash hider and mated to a Geissele 17-4 PH stainless steel gas block and a Geissele extended carbine-length gas tube — purpose-selected components that reflect the Geissele quality standard even in the ALG Defense price tier. The 08-577B El Corto buffer tube is outfitted with Geissele's own Super 42 Braided Wire Buffer Spring — the three-strand braided wire design that displaces energy, decreases the risk of spring failure, and delivers roughly 15% stronger return force than a standard spring for enhanced reliability with dirty conditions and steel case ammunition.
