Brownells AR-15/M16 Upper Receiver Action Block Black

Description

Product Overview

The Brownells AR-15/M16 Upper Receiver Action Block is a heavy-duty vise block that securely clamps AR-15/M16 receiver halves to help prevent crushing, twisting, or distortion during cleaning, assembly, repair, and barrel nut work. High-pressure, solvent-resistant Rynite surrounds and supports the upper receiver both inside and out so barrel removal/installation can be done safely and efficiently.

Key Features

• Injection-molded Rynite construction helps resist solvents and withstand high vise pressure
• Supports the upper receiver inside and out to reduce the risk of damage during barrel work
• Torque tested to 200 ft lbs to help ensure barrel-nut removal/installation stays controlled
• Designed to transfer torque from the barrel nut to the block and insert instead of the receiver
• Fits A1, A2, and standard flattop upper receiver configurations for reliable clamping

Secure your AR upper firmly in the vise with this purpose-built action block from Brownells for safer, more consistent assembly and maintenance.
