Good morning everyone and thanks for joining us again for Silencer Saturday, brought to you by our friends at Yankee Hill Machine, manufacturers of the new R9 9mm suppressor that is now starting to ship out to distributors and dealers. Last week we got a sneak peak at the soon to be released SIG Sauer suppressors, Next Generation Squad Weapon (NGSW) submissions, and 6.8mm three part case ammunition. This week we take a look at the Liberty’s Defense straightJacket silencer cover, an impressive blend of fabrics that keeps hot cans away from hands, gear and anything else at risk of bursting into flames.
SILENCER SATURDAY #136: Flame Proof! Liberty’s Defense Silencer Cover
I have been unlucky enough to burn myself several times on hot suppressors during or after extended strings of fire. As silencer owners, we tend be obsessed with checking to make sure a can is securely mounted to the barrel. Rimfire and slow-fire pistol caliber setups can usually be checked barehanded without the fear of serious injury. Semiautomatic centerfire models, however, get very hot, very fast and even a momentary touch can inflict serious burns. Twice while testing rifle silencers I have reached down to twist/tighten and ended up losing a bit of skin.
Over the years I’ve tried my share of covers from Cole-TAC, Bowers, Burnproof Gear and Magpul. Honestly, they are all quality products. Like most things in life, there is no free lunch – lighter, less expensive, lower profile covers are great for reducing mirage and slower rates of fire, but can’t withstand heavy use. On the other hand, heavy duty silencer covers can be bulkier, heavier and more expensive while being able to withstand heavy firing schedules. In between there are some key attributes you should look for when picking a cover.
- Burn Protection – Save your skin.
- Gear Protection – Hot suppressors can melt bags and web gear.
- Mirage Control – Heat rising off a silencer can distort the view through magnified optics.
- Secure Attachment – Under fire, covers can slip forward without a solid tie down system.
- High Speed, Low Drag Looks – Yeah, it’s pretty freaking important.
The straightJacket from Liberty’s Defense hits all the important points while being able to withstand extreme, prolonged temperatures.

A combination of Kevlar, basalt, amorphous silica, and aluminized silica joined together with Kevlar and stainless steel thread to create the full auto rated Liberty’s Defense staightJacket Thermal Attenuator, which provides absolute flame resistance and heat mitigation for direct and continuous contact with your silencer’s extreme continuous temperatures up to 2,000°F and short excursions of 3,000°F.
The Liberty’s Defense straightJacket Thermal Attenuator (Patent Pending) utilizes four separate layers of absolute flame proof high temperature fabrics which provides direct and continuous contact with suppressor extreme operating temperatures up to 2,000°F and a flash short excursions rating of 3,000°F. The fabrics are stitched together with stainless-steel thread to ensure the integrity of the cover’s absolute heat resistance. The adjustable retention system consists of a marine grade stainless-steel cable which is coiled with constricting pressure across the full length of the suppressor and is overlapped on the barrel end of the suppressor. The cable is locked into a marine grade stainless steel snap shackle that is attached to a Mil-Spec Kevlar webbing and steel slide which allows tension adjustments. The simplicity of the cable and snap shackle design affords the shooter ease in the ability to install or remove the straightJacket in only a few seconds.
Liberty’s Defense has an extensive library of silencer models that are used to make an exact-fitting cover. I purchased a cover for my Delta P Design Brevis II Ultra, which is unique enough not to be in their library. The construction of a custom cover adds a week or two to the order timeline. Drop the dimensions of your silencer into the ordering fields and add to your cart.
The straightJacket is a slip fit design that uses a stainless steel braided cable and shackle that tightens it equally on all sides. In addition, the cable inside the cover’s channels tightens the mount end of the cover a little more to keep it from slipping. It’s a secure setup.
The Delta P Brevis lives on my go-to 11.5” 5.56mm SHTF AR-15, which I consider to be a “fighting“ carbine that needs to function flawlessly under adverse conditions. As a semiautomatic weapon and me not being prone to mag dumps, I rarely push the performance limits of the straightJacket. But this cover really is exceptional at preventing heat transfer. After two rapid fire 30 round magazines in a short barreled rifle, it is still cool enough to touch with a bare hand. There is no melting, no smoking and no other signs of failure.
Here are some of the “no free lunch” things to keep in mind. This cover weighs slightly more than other options on the market (mine is 4 ounces). It is also less flexible than other covers, acting less like a fabric and more like a stiff braided polymer. And costs nearly twice as much as other available options. But if you need extreme high heat resistance from a suppressor cover, there probably isn’t a more robust option available on the commercial market. For my defensive rifle setup, it is nearly perfect, with weight being the one minor detractor.
As an aside, I’d suggest picking up a pair of flame resistant gloves from Mechanix Wear, Vertx or other manufacturers. Even with a good cover, gloves can save your fingers from serious injury.
Thanks for reading. Be safe, have fun and we’ll see you back here next weekend for another Silencer Saturday.
