JK Armament and Garand Thumb Set a World Record

JK Armament and Garand Thumb Set a World Record

We met up with Garand Thumb and set the record for the world’s longest suppressor! And it’s all on video!

 

Get this: a whopping 1,380 baffles! That’s right, we screwed together the equivalent of over 276 JK suppressors until the darn thing was a full 25 yards long.

It all started with the brand new JK G.O.A.T. HF (High Flow), our quietest suppressor yet! Then Garand Thumb and the JK team went for the record by adding one section of baffles at a time. Each time a few more feet of length was added, we fired a shot to check for baffle alignment and also did some decibel metering.

We were pleasantly surprised to see how well bore alignment was maintained, even over completely insane and unreasonable quantities of baffles. We didn’t destroy a single baffle, though a few times the bullet did lightly touch the inside bore of the front cap, leaving a scuff mark and destabilizing the projectile.

On the other hand, we were not particularly surprised to see sound volume levels at the shooter’s ear remain more or less the same once we got beyond the length of the G.O.A.T. HF’s full length configuration as it ships to our customers. As it turns out, that very length is right about where we’ve suppressed enough of the muzzle sound volume that most of what’s happening at the shooter’s ear is coming from the ejection port and the action of the AR-15 cycling.

Though it got quieter at the muzzle as the suppressor grew to insane lengths, the shooter’s experience back at the firearm didn’t change much. Very interesting!

With this build I can suppress every .30 caliber and smaller rifle and every 9mm and smaller pistol in my collection. Whether I’m running my AR-15 or AR-10 hard – even full-auto – or I’m on a spot-and-stalk hunt with a lightweight bolt-action rifle, or I’m plinking or varmint hunting with a rimfire rifle, or I’m shooting pistols and pistol caliber carbines in 9mm or smaller, this one suppressor can be configured so it’s ideally suited for each and every one of those things and more.

Heck, if I also owned a 45 ACP pistol and/or a 458 SOCOM rifle or a .45 cal lever action I could add 5x .45 cal LT and/or PRO Pistol baffles and have those guns covered, too!

It’s so lightweight that it doesn’t need a booster!
