Frequently Asked Questions
How do you torque the barrel nut?
Military specification for the barrel nut calls for torque of 30-80 ft. lbs. The reason for this broad range is to allow the nut to be timed for the gas tube to pass through the barrel nut and align to the upper receiver. The design of our barrel nut does not require this timing, making the upper ranges of torque unnecessary. By torquing the barrel nut using the handguard's clamping ability, we are able to achieve the 30 ft. lbs. required by military specifications. We also supply a spanner wrench allowing the user to apply greater torque for fixed applications.
What are the benefits of the Rapid Take Down system?
The RTD allows you to easily convert your rifle into a small package that will fit into a backpack, messenger bag, etc.—any bag that is long enough to contain the barrel and gas tube can transport your firearm! It is inconspicuous and easy to transport. It is also very easy to deploy; people with very limited experience can take the rifle from the bag to ready to fire in under 30 seconds. It is also great for storage; removal of the barrel renders the rifle incapable of firing. And to detail clean inside the chamber, there is no easier method than to be able to remove the barrel.
This system also allows quick caliber conversion with only another barrel. .223 and .300 blackout use the same bolt and magazine, so a quick barrel change gives you two calibers in one rifle.
