GENERAL DESCRIPTION

This operator’s manual details the proper use and maintenance of the Freedom Forge Armory GASCAN QD, GASCAN DIRECT THREAD, AND BACKBLAST suppressors. Direct-thread silencers couple to the host rifle using a section of screw threads on the barrel’s muzzle. Direct-thread is the traditional method of attaching a silencer and is popular for its rigid interface and simplicity. QD silencers use a special muzzle device and enables users to securely install the silencer onto an Freedom Forge Armory 3 port muzzle break or flash hider (all of which will be referred to as “muzzle devices”). QD silencers can be attached to muzzle devices in seconds, using an intuitive motion and gross motor skills.

WARNING – Freedom Forge Armory Titanium rifle silencers are designed for precision, low rate of fire applications. Using a Freedom Forge Armory Titanium rifle silencer in a high volume semi-automatic or automatic fire application may lead to property damage, personal injury and/or death.


WARNING - A popular trend among silencer consumers is the practice of using one silencer of a given caliber on numerous host firearms of equal or smaller caliber. The GASCAN QD and GASCAN DIRECT THREAD are designed for this purpose. This practice is safe, provided the user answers the following questions in the affirmative:


  1. Is the alternate caliber diameter equal to or smaller than the caliber designated on the data panel of the silencer?
  1. Does the alternate caliber produce a muzzle exit pressure equal to or less than the muzzle exit pressure of the caliber designated on the data panel of the silencer?
  2. Does the alternate caliber cartridge have a case capacity equal to or less than the caliber designated on the data panel of the silencer?

  3. If the answer to all three of the above questions is, “Yes”, dual use of an Freedom Forge Armory rifle silencer is safe for the alternate caliber in question.    

IT IS THE RESPONSIBILITY OF THE USER TO DETERMINE THE COMPATIBILITY OF HOST FIREARMS AND SILENCERS PRIOR TO DUAL USE.


WARNING – Freedom Forge Armory GASCAN QD, and GASCAN DIRECT-THREAD silencers have a safe maximum working pressure of 63,820 PSI, if this pressure is exceeded it may lead to property damage, personal injury and/or death.


WARNING – Freedom Forge Armory GASCAN QD and GASCAN DIRECT-THREAD silencers have a bore diameter large enough to safely accommodate a 9mm bullet (.355 Caliber). Use of bullets larger than 9mm (.355 Caliber) may lead to property damage, personal injury and/or death.

FREQUENTLY ASKED QUESTIONS NOT COVERED IN THIS MANUAL:


Q: It looks like my silencer has been used. I thought it was new?

A: The silencer is new, some Freedom Forge Armory silencers are randomly selected from production and tested before they are sold to ensure that they meet our strict quality controls. This includes proof testing. These few rounds will not affect the performance of the silencer and ensure that we are maintaining our high standards of quality.


Q: I lost my mounting end cap tool but I found another tool that will work, is it OK to use that tool?

A: No, only the provided tool is approved for use when removing the mounting end cap to install the booster. If you lost or misplaced the tool please contact Freedom Forge Armory for a replacement.


Q: Can I use my Freedom Forge Armory BACKBLAST silencer with .22 LR ammunition?

A: Due to lead fowling associated with .22 LR it is not recommended to use the BACKBLAST as a dedicated .22 LR silencer. Occasional use of .22 LR ammunition will not effect performance. After use of .22 LR ammunition it is recommended to fire 4 to 5 rounds of full power .233 or 5.56mm through the silencer to remove lead fowling. For dedicated .22 LR use the Freedom Forge Armory SILVER is a better choice.


Q: After a heavy range session I can't get my silencer to thread off of my muzzle or QD Mount.

A: The silencer has most likely become carbon locked. This occurs when carbon builds up around the threads during prolonged firing. Direct-thread silencers are more prone to carbon lock than QD Mount silencers. To fix a carbon locked silencer spray a generous amount of gun cleaning solvent around the shoulder of the of the threads or QD mount and allow it to soak over night this should break up the carbon enough to get the silencer off. You may need to use a strap wrench for more leverage if the carbon lock is severe. Once the silencer is removed immediately clean and inspect the threads of the muzzle or QD Mount, and the internal threads of the silencer for damage using the care and maintenance instructions in this manual. Regular cleaning of the mounting end cap threads, QD mount threads, or muzzle threads with help prevent carbon lock.   


Q: Can I purchase additional caliber monocores or mounting end caps for my silencer?

A: No, per BATFE regulations every part of a silencer is a controlled item. Possession of additional monocores or end caps constitutes constructive possession of an unregistered silencer. When a silencer is returned to Freedom Forge Armory for service or repair the old parts are destroyed and replaced one for one. 


Q: I damaged my outer tube can it be replaced?

A: No, per BATFE regulations the outer tube is the registered part of the silencer and can not be replaced with an outer tube with the same serial number. The unservicable outer tube will be destroyed and a new outer tube with a new serial number will have to be transferred on a ATF form 4.   


Q: There sure are a lot of warnings about property damage, personal injury and/or death in this manual. 

Do I really have to follow all of them?

A: Yes, those warnings are there for a reason. Warnings are written in blood. When used properly with the right ammunition a silencer will provide a lifetime or more of use. If used improperly or with the wrong ammunition it's like holding a hand grenade next to your face and pulling the pin. You wouldn't do that so follow the instructions in this manual.
