Product Summary
The Crosstac AICS Maintenance Block is a precision-engineered tool designed to securely hold and clean any short action AICS magazine-based rifle. CNC machined from solvent-impervious HDPE plastic, it features multiple nylon set screws and four tension screws to ensure an extremely tight, stable fit in the magwell. The block includes two milled angles, allowing you to mount the rifle parallel to the vise or at a 10-degree downward tilt to ensure solvent flows toward the muzzle. Additionally, the top of the block is designed with bolt clearance, making it an ideal choice for trigger tuning and detailed maintenance work.
