Modular AR-15 / AR-10 Aluminum Maintenance Block Kit

One Serious Workholding System for Both Platforms.

The CROSSTAC® Modular AR-15 / AR-10 Maintenance Block Kit is our heavy-duty aluminum workholding solution for shooters and armorers who work on both platforms.

CNC machined from 6061 aluminum, the modular system gives you a rigid, repeatable way to secure the firearm for maintenance, assembly and bench work without clamping directly on the receiver.

This is the one to choose when a maintenance block isn't an occasional-use tool—it's part of your bench.

Features

• Modular system for AR-15 and AR-10 platforms

• CNC machined from 6061 aluminum

• Rigid support for maintenance and assembly work

• Keeps vise jaws off the receiver

• Built for repeated bench and armorer use

• Made in USA by CROSSTAC®

If you work on both platforms, build the bench around one system.
