Frequently Asked Questions

What is the Gat Crank and how does it work on an AR-15?

The Gat Crank is an accessory that attaches to the trigger guard of an AR-15. It mechanically pulls the trigger multiple times per handle rotation, effectively increasing the firearm's rate of fire. Each full revolution of the crank fires three rounds.

What rate of fire can the Gat Crank achieve?

During testing by Jerry Miculek, the Gat Crank achieved a rate of fire of 681 rounds per minute (RPM) when attached to an AR-15. This performance is comparable to the lower end of a standard M16's cyclic rate.

Are there any issues when testing the Gat Crank with a suppressor?

Yes, using a suppressor with the Gat Crank can cause problems with shot timers. The reduced report volume may be too quiet for the timer's sensor to reliably register each shot, leading to inaccurate readings.

What tools are needed to test the Gat Crank's performance?

To test the Gat Crank's performance, you will need the Gat Crank itself, a compatible AR-15 firearm, and a reliable shot timer like the PACT Club Timer III. Optional accessories for demonstration include a suppressor and high-capacity magazines like a 60-round drum.
