By Tom Murphy
A*B (American Built) Arms is a Type 07/NFA firearms manufacturer based in Glen Rock, PA, which builds both complete rifles and chassis systems for existing rifles.

They offer top quality, precision-engineered, Swiss-machined internal components and polymer chassis parts for outside firearms manufacturers to install their own logos.
Chassis System
A*B Arms MOD*X GEN III is a chassis system engineered to accept various makes and models of existing rifle-barreled actions. The rifle used for this article is a Remington M700 AAC-SD in .308 Winchester. The chassis is primarily aluminum, anodized to MIL-SPEC Type III which is an electrochemical hard coating process that creates a controlled oxide film on the surface of aluminum. It is normally used in applications like firearms that require a corrosion-, abrasion- and wear-resistant coating. During the anodizing process a uniform aluminum oxide layer is formed on the metal’s surface. This penetrates the aluminum. The process involves submerging the parts in a cold (32-degree) sulfuric acid bath for anywhere from 20 minutes to 2 hours.
At 3 pounds, 2 ounces, the MOD X is quite light. Its lightweight, 11.5-inch, free-floating handguard features the KeyMod system on the top and sides. There are also conventional mounting slots on the two sides. It’s a modular foundation that allows various mission-specific accessories to be installed depending on the operator’s requirements. A 0 MOA scope rail is standard; a 20 MOA rail is optional.
The chassis comes standard with an A*B Arms fixed-adjustable Urban Sniper Stock and the A*B Arms SBR pistol grip. The grip is made from high fiber count nylon and is specifically designed to fit the operator’s hand. It has a battery compartment that will hold one CR123 or 2 AA batteries. Any MIL-SPEC, AR-type butt stock or pistol grip can be substituted.
The length of pull is adjustable from 10.62 inches to 15.69...
