Warranty Information

To better serve our clientele as well as learn about how our products work in the field, we are making some changes to the warranty policy here at Liberty Suppressors. These updates are effective 1 MARCH 2014.

For all future baffle strike warranty requests, we will be collecting the following data in an effort to figure out the problem with the strikes and to see if there is any trends that develop based on ammunition, weapons or suppressor issues.  Each suppressor is tested here at the facility with live ammunition to confirm that it is free of baffle strikes before it leaves to go to the customer.

I received the Mystic back a few days ago, and wanted to write and convey how happy I was at the speed and quality of the repair.  I have not tried it yet, but based on the appearance and how sturdy it now feels, I am already singing its praises.

I’m blown away with how great of a company you and your team are. I wish there were more out there like you… ~ Kyle F.

Warranty

Liberty Suppressors offers a limited lifetime warranty on materials and craftsmanship and will repair or replace, free of charge, any sound suppressor manufactured by Liberty Suppressors should it be found to be defective due to these two reasons. 

Normal Wear

Liberty Suppressors uses the highest quality materials in the construction of our suppressors. There are times when, even with the toughest of materials, suppressors will wear out from use. Liberty Suppressors does not warranty this wear as it is not a defect in materials or craftsmanship. Accelerated wear will occur when using short rifle barrels where there is not enough barrel length to consume all the gunpowder during the burn in the gun. The shorter the barrel, the quicker the wear becomes. Also, silencers that are full auto rated are rated for full auto, in moderation. Just make sure not to overheat. All things wear out from use, even silencers.

Negligence

This warranty does not cover damage to the sound suppressor and/or host firearm resulting in whole or in part from criminal or negligent use, improper or careless handling, modifications, defective, improper hand-loaded or reloaded ammunition, or neglect. This warranty does not cover a suppressors use on center fire rifles w/ barrels shorter than 10 ¼”.

Improper Installation

This warranty does not cover damage to the sound suppressor or host firearm due to improper installation of the Sound Suppressor, or an improperly threaded barrel. (See additional “Important” sheet for testing barrel prior to installing suppressor)

Government Surplus Ammo

This warranty does not cover damage when using Government Surplus Ammo. Surplus ammo probably has issues with it, or it would not be surplused. We do not recommend the use of reloaded ammunition. We recommend reputable ammo only, with the use of your suppressor.

Issues with Shooting Loose

Please note that suppressors are prone to loosening due to thermal expansion. It is important to check the suppressor after firing 5 or 6 rounds to ensure it is not “shooting loose”. If it is loose, retighten and continue use. It should be checked again periodically. CAUTION: The suppressor can get very hot during use, when checking to see if the suppressor is tight on the firearm make sure to protect yourself from this heat.

Disassembly

Sealed Suppressors need not be cleaned or taken apart.  The Kodiak is provided with disassembly instructions.  If a sealed unit, which is a suppressor that is not intended to be disassembled by the user, is returned with evidence of disassembly by anyone other than the manufacturer, this warranty is void.

Sealed Suppressors are covered for cleaning, only after a significant number of rounds have been fired thru the silencer and it has filled up w/ “crud”, this amount being easily quantified by weighing the suppressor.  The suppressor is eligible for a free rebuild when it weighs at least 1.5 times the amt, of when it was new.  At this point, box it up, send it back and we will rebuild, refinish and send it back to you…. For  Free.  You will need only to send payment for return shipping.

Additional

 

EFFECTIVE IMMEDIATELY: DUE TO INCONSISTANCY IN CONCENTRICITY WITH ADAPTERS FROM OTHER MANUFACTURERS, WE CAN NO LONGER RECOMMEND OR WARRANTY THE USE OF THEM WITH LIBERTY SUPPRESSORS. WE CAN ONLY RECOMMEND THE USE OF MOUNTS PURCHASED FROM LIBERTY SUPPRESSORS.

Charge to Owner

Any repairs not covered by this warranty will be charged to the owner.

IMPORTANT- FOLLOW THESE STEPS BEFORE USING YOUR NEW SUPPRESSOR !

Explanation

You will need to make certain that the shooting system is ready for the new piece to be added (the silencer). Take the following steps to check that the weapon and ammunition combinations that you plan to use will be compatible with a silencer being added BEFORE installing the suppressor on your weapon.

But, just like adding new precision parts to a production automobile, there is the possibility that things will not interact properly causing damage to the system. Therefore, you will need to make certain that the shooting system is ready for the new piece to be added (the silencer).

1 - Bullet Stability

Test fire your gun/ammo combination at 3 feet and 10 feet into a cardboard target to check that the bullets are leaving the gun in a stable fashion. Anything that is not making a perfectly round hole should be considered suspect and not used with a suppressor attached.

2 - Thread Alignment

The alignment of the threads is the cause of more baffle strikes than any other reason from our research. The threads should be aligned with the BORE and not the outside profile of the barrel. Many gunsmiths mistakenly assume that the outside of a gun barrel is aligned with the bore. Many times this is not the case. Always confirm that the silencer is aligned with the bore by visual inspection. On handguns, remove the barrel if possible and install the silencer then look at the blue sky (not the sun) and visually confirm that the barrel and silencer are aligned, if the shadow of the silencer is not evenly spaced around the end of the barrel, then they should be checked with a dial indicator or a correctly fitted range rod. See your gunsmith for help with this action.

3 - Torque Shoulder

The torque shoulder at the back of the threads is another area that causes many problems. We normally recommend that there be at least .050” wall height for the silencer to breech against. This means that the diameter of the barrel at this point would be at least 100” larger than the thread diameter. Some guns do not have this much material to work with so check to be sure that the silencer is stopping against the shoulder and not running over it. There are some SIG barrels on the market that are very thin and this is a problem with them. To eliminate this problem with a thin barrel, the suppressor should breech on the muzzle of the barrel instead. There will always be a shoulder here that can be used, but this generates greater expense as normal manufacturing techniques cannot be used to make these parts.

 

DO NOT USE ANY SPACER/ WASHER OF ANY KIND BETWEEN THE SILENCER AND THE HOST FIREARM.

4 - Cast Bullets

Cast bullets offer the shooter a lot of bang for his buck in that they are very inexpensive and allow the shooter to enjoy his hobby more for the same money. Be careful though, these bullets are prone to vaporizing lead and depositing it on the first few baffles in the silencer. The problem comes when it starts to constrict the bore line and generates baffle strikes.

5 - Thread Size

There is only one instance where I have found this to be a problem and that is with the following two thread pitches. 9/16-24LH and 14x1mmLH. These two threads are very close in size with the pitch of the Imperial thread being .04166” and the metric thread pitch being .03937”. Since there is only .0023” difference in the pitch of these two threads, it is possible to install a metric threaded unit onto the imperial thread if it has been threaded a little loose. It will not fit properly and is considered dangerous by us. Do not do this. Be sure of your thread size before installing the silencer on it. Get with your gunsmith if you are unsure and have him measure it.

6 - Issues with Shooting Loose

Please note that suppressors are prone to loosening due to thermal expansion. It is important to check the suppressor after firing 5 or 6 rounds to ensure it is not “shooting loose”. If it is loose, retighten and continue use. It should be checked again periodically. CAUTION: The suppressor can get very hot during use, when checking to see if the suppressor is tight on the firearm make sure to protect yourself from this heat.

Final Thoughts

Once all these things have been checked, then fire the weapon, ammo, and suppressor together. Doing these precautions will eliminate many of the possible ways to damage your registered NFA item that you spent so much time and energy getting into your hand.

We do not recommend firing your suppressor until all of this has been checked and found to be in correct order. Our warranty policy will not cover gross negligence on the part of the end user.

Point of Impact vs Baffle Strike Issues

Baffle Strikes

Baffle strikes will cause erratic group sizes, most of the time causing the groups to open up and shift dramatically. The direction of shift is not an issue, but rather that it IS shifting and there is a dramatic change in accuracy of the groups that is negative in nature.

Point of Impact Shift

Point of Impact Shift is caused by the harmonic disturbance of the silencer on the end of the barrel. Sometimes the gas inside the silencer can also disrupt bullet flight, but most of the time it is due to the weight of the silencer being added that changes where the bullets land on the target. Most of the time, the gun will shoot low and to the left. This is based on our own personal experience with firearms here at the test facility. The biggest difference between this and baffle strikes is that the group size will almost always be the same or slightly smaller. So the gun will shoot better most of the time, just in a different place. In some extreme instances there have been changes of up to 12”, but the groups still run good. This is a function of several factors that affect the barrel such as barrel harmonics, size of the barrel (diameter), barrel length and fluting, and length and weight of the silencer. Barrel whip is dampened when the silencer is added. The silencer being added to the end of the barrel will also pull the barrel down with gravity as well, causing the gun to shoot low by a function of gravitational pull.

 

If you have baffle strikes or other possible warranty issues, email a picture and general description of your problem to support@libertycans.net for initial evaluation. If our warranty department determines that you do indeed have a warranty related problem, they will issue an RMA number and send you an Issue Resolution Form to fill out and send in with your suppressor and any related accessories you are comfortable with sending in. We strive to get warranties evaluated and repaired in seven to ten business days for your convenience.
In the rare instance you should experience a problem, we will try our best to get it resolved. Please refer to the information above to see if there are any precursor issues to your problem. Thank you.
