The Ergo AR-10 armorer block is an invaluable addition to your workbench, securely holding your firearm in place for cleaning or maintenance. While it was originally designed to aid in installing and removing pins from your platform, the block is suited to helping you perform various simple and complex tasks.

Top Choice

The AR-10 bench block is one of the most useful maintenance accessories available for AR10 shooters who perform their own maintenance. The firearm’s mag well slides snugly down onto the block, holding your AR10 securely in place, so you have both hands free to work. The block is designed with a variety of grooves, notches, and holes on both sides for holding the upper and lower receiver as well as the front sight and charging handle.

High Quality at Low Cost

The Ergo AR-10 armorer block’s rugged one-piece design is made from a high-impact, non-marring black urethane polymer to last through year after year of use. Moreover, as it weighs in at just seven ounces and measures 6 1/8 inches high by 2 inches wide by 4 1/4 inches long, the block won’t take up precious space on your workbench.

Ready for Business

The AR-10 bench block is ready to use right out of the box and works with all rifles having SR-25 pattern magazines. The simple one-piece block can be attached firmly to your bench with clamps or permanently attached with screws through predrilled mounting holes.
