Can Question
« on: October 30, 2018, 12:38:22 PM »

Does using a brake and or flash hider as part of a QD system for a suppressor affect the wear and tear on a suppressor? Essentially what I’m asking is does one or the other(hider/brake) put less or more wear on a suppressor? If any difference

No it would not. The manufacturer has designed the brake/flash hider to work with the can.

I have been seeing a lot of people posting about there qd mounts are wearing causing the can to loosen up a hair or become non-cocentric  which is causing them to have can strikes or launching their can down range.....   quite a few lately.....

Who are the manufacturers of these cans? I would like to know more about this as it is the first I am hearing about this.

That sounds like they could be using crush washers to set the timing of the mount which is a no no. If the crush washer doesn't compress evenly it can cause can strikes.

We are required to use Surefire and TBAC quick disconnect suppressors on our military contract weapons. Both those items utilize a specific muzzle device, the Surefire being a Flash Hider, and the TBAC being a true Brake.

When installed properly and timed correctly we have never ever seen an issue with a baffle strike, excess wear and tear, or any loosening of the locking mechanism.

I have seen baffle strikes with the Surefire silencers quite a bit when the brakes/flash hiders aren’t installed properly. Additionally, using a crush washer is a major no no when using a suppressor.

Lastly, according to Surefire, the Flash Hider allows for slightly less PSI inside the silencer than their brakes.

As with all metal-to-metal contact surfaces, the more you have sliding metal contact without lube, the more wear you will experience.  If the person is taking off and putting the can on all the time, specially if doing so without any cleaning, the unburned residues act as a grinding compound and can increase the wear on concentric mating surfaces over time.  Powder residues can also foul the locking mechanism, causing inadequate or insufficient lockup.  That takes quite a bit of time and a LOT of attach/detach cycles though.

There have been instances of the teeth wearing down on mounts like the AAC 51 tooth muzzle devices.  That said, I have those on a number of guns, and have had no problems - I don’t move my cans around that much and I depress the lever while mounting a can.

99% of the time a can launch or baffle strike is operator error. Make sure you have a professional mount your muzzle device. Pay whatever it is where ever you want but get it done right the first time.

We had one last week at the range, bad too, 3 baffles and the end cap on a sealed unit.
