Frequently Asked Questions

What tools are needed to install an AR-15 forward assist?

You'll primarily need a 3/32-inch roll pin punch for standard installations. If your upper has a threaded pin, a 1/16-inch hex or Allen key is commonly used. A small hammer or persuader is also helpful for tapping the roll pin.

Visually inspect the forward assist assembly. A roll pin will appear as a small, hollow cylinder inserted through the receiver and assembly. A threaded pin will have visible threads and will screw into place.

What is the correct orientation for installing the forward assist spring and assembly?

When inserting the forward assist and its spring into the upper receiver, ensure the flat end of the forward assist assembly is facing towards the Bolt Carrier Group (BCG) channel. This allows for proper function.
