I shoot a shit load of suppressed rounds through a high power rifle, the only draw back that I have any complaints about is the mirage that appears after a few rounds, as a can heats up extermely fast, do the kevelar mirage covers help or work at all? any input would be appreciated.
 
Re: suppressor / mirage cover do they work???

Before I got my TAB cover after 20 rounds of 308 thru my Shark the heat waves were considerable, the cover also is nice to have when removing the can just after shooting.
 
Re: suppressor / mirage cover do they work???

I have a TAB cover, and it works ok for a little bit. After a few more rounds, the heat has to go somewhere, so it goes out the end of the can, or down the barrel. Either way the mirage is still visible, and given the choice, I'd rather have my can really hot than my barrel. The covers don't absorb the heat, they just move it to somewhere else.
 
Re: suppressor / mirage cover do they work???

Yes they work.

You're not exactly correct medic103, the heat is absorbed but eventually it'll come out somewhere. I could easily make you a cover that keeps all the heat inside. The bad thing about that would be that if you run the can hard enough your can would suffer damage from the heat having nowhere to go.

It's a fine line you walk with a can cover, the heat has to go somewhere. I'd rather have a guy calling who ran his can so hard that he melted the cover than to have a guy calling all mad because his can melted and ran out the end of his cover. We've recently begun working on the 5.56 rated covers again and hopefully we'll have something positive to report on that soon too.

I recently got a report back from some testing that was conducted using M110 suppressed rifles. The ran the test to the failure of the SAS cover. We currently have samples being tested to see if we can extend the amount of time that the mirage is dampened with no damage to the covers or cans.

Tested with 2 x M110 SASS
Daylight hours
94 degrees
3 x Sniper Instructors
Standard Iron Maiden targets (40” x 20”)
Conditions:
1 x M110 fired 1 round every 2-3 seconds with no suppressor sleeve.
1 x M110 fired 1 round every 2-3 seconds with a suppressor sleeve.
Both weapons continued with this rate of fire until barrel mirage was to great to accurately engage targets.
Both weapons engaged the same target at approximately 467 meters.
Results:
M110 with no suppressor sleeve began to have significant barrel mirage at 21 rounds; shooter was unable to engage targets and be able to identify what he was engaging after 25 rounds.
M110 with the suppressor sleeve did not have any significant barrel mirage until 70 rounds (Sleeve melted to suppressor).
It left a small amount of residue on the suppressor
Sleeve was able to be removed in a quick manner due to the Velcro securing method.

Tony,

I definitely don't want that, and I understand what you're saying. Good post because it shows an application where the cover works well. I definitely see where in a comp, or scenario like you mentioned the cover would be of an advantage. I don't use mine like that, but next time I'm at the range, I'll do my own little test and see at what round count I notice the advantage of the cover.

If you buy the Velcro model, be sure that is is tightly closed. I've been told that if they are loosely secured, they might get launched down range, 5 yards or so. I'll never tell how I knows that.
 
Re: suppressor / mirage cover do they work???

Here's some information I posted on another thread about the SAS covers.

We also have the SAS 3 version, now which one do you choose.

If the new website ever gets off the ground it'll have this model as well. Currently if you want to order an SAS 3 you need to ask Lisa to make it an SAS 3 in the comments section when placing your order.

The SAS 3 does the same thing as the velcro SAS1 velcro model, but in a more streamlined package that has no velcro.

It looks like a SAS2 shock cord version from a distance but has no shock cord in it at all. The back has an internal ridge to keep it from sliding forward and the front has nothing to keep it from sliding back on the barrel.

Here's a picture of some SAS2 Shock cord covers. You can see that each end is kind of wrinkled up from the shock cord pulling the ends slightly closed.

Here are two pictures of the SAS3 version. You can see that there are no seams sewn around each end and that the ends are not wrinkled up. The cover comes flush to or maybe just behind the muzzle of the can. As you can see, it's a much more streamlined cover than the velcro version and will allow the cover to easily be slid to the rear to allow the can to cool and then slid back onto the can to resume firing.

Here's a SAS1, velcro cover for a complete set of pictures of all three models on one page

Some background on the SAS2, and SAS3

The SAS 2 was developed for some people who build items for the military. They asked me to come up with a cover that had no front or back so that if it was given to a soldier and the directions were lost there was no way to install it backward.

Advantages are there's no front or back, it won't slide back onto the barrel exposing the metallic can to sounding like a tuning fork if it's banged against trees, rocks, etc. when stalking.

Disadvantages would be, a little difficult to get on due to the shock cord at both ends, if you shoot a string of fire and the can is very hot and you decide you want to slide the can back off onto the barrel to let the can cool down you're going to ruin your cover. The outer Cordura is actually rolled under the can a little on the ends and if you pull the cover back over a hot can the Cordura will melt when it gets into the hotter part of the can. We have cans with over 2000 rounds of .338 LM through them with no damage to the can, and covers with over 3000 rounds of .308 with no damage. This cover is designed to mainly be left on the can.

The SAS3 came about when Zac Smith and Ray Sanchez of Thunder Beast suppressors contacted me and wanted the SAS1 and SAS2 combined. They wanted a stream lined cover like the SAS2, but no shock cord on the ends. They tested several prototypes out until I got the sizes like they liked, and here we are. The SAS3 has no Velcro, and no Cordura that can come in contact with the can. The back of the cover has a ridge that is built up with the inner heat resistant material to prevent the can from sliding forward under recoil. There is no shock cord in the front of the can.

Advantages would be, easy to get on and off, very easy to slide back onto the barrel to allow the can to cool and then very easy to slide back up onto the barrel when shooting begins again.

Advantages would be, it must be either installed on the can before the can is installed on the rifle or slid back onto the barrel before the can is attached to the rifle and then slid up onto the can. Will not work with cans like the Surefire that have the locking tab that sticks out to the side of the can because the built in ridge won't usually fit over it. The SAS 1 cover would be needed in this situation.

Re: suppressor / mirage cover do they work???

Embarrassing story, I inadvertently put mine on backward and did not notice it had slid forward.....let's just say I need a new cover.

While they work well enough in the heat I think they provide the biggest advantage in the cold.


Good luck

They have a good aerodynamic quality in addition to being well made. Says alot about the product, when abuse like that doesn't hurt it.
 
Re: suppressor / mirage cover do they work???

Can the subguns covers be quickly and easily pulled back for cooling?

The most common usage model we see around here, in our matches and practice, is that we push the cover forward over the can just before we get to the firing point, do all the shooting, and then as we pack up the gun, pull the cover back to let it cool.
 
Re: suppressor / mirage cover do they work???

I still use the SAS2 covers. I've never tried the SAS3 version. I mostly use Ops Inc 16th & 12th Model, and AAC M4-2000, SPR/M4, Cyclone and 762-SD (18-tooth mount) suppressors with these covers and haven't had any problems pulling the covers back over 90% of the suppressor after a string of fire and then reposition the cover. Just my experience though.

I love these covers and use them frequently.

Quickly no, but with the ribs they tend to run cooler. They cool much faster than others I've tried,(cover on) do to the ribs.

I've ran them on FA and still removed the can with bare hands, when I needed to remove the can, quickly.

Only time I've even seen can heat (in scope) was at Hardrock right at the end of a 20 rd .308 string, shot in 6-7 minutes.

Shooting FA (with in reason, no 20rd mag or BETA dumps, M16 An M14) I've not had issues with the covers or cans.
