PRE-ORDER Guidance
As you are probably aware, recent updates to ATF's eForm approval process has resulted in drastically improved turnaround times. While this is certainly a positive change, it has also had a predictable impact on suppressor inventory across the industry.
With that in mind, if you know you want a particular suppressor (or three) and it isn't in stock, your best bet is to place a "PRE-ORDER" so that we can purchase your desired suppressor the moment it becomes available from our distributors. If you wait until it shows in-stock on the website, you might miss your opportunity. PRE-ORDER helps us seek out and purchase what you are looking for. This is true whether you buy from us or someone else.
Thank you for considering Longbow Arms, we hope to earn your business.

CAT NOAH 718
The CAT NOAH 718 combines extreme durability with low backpressure and excellent sound performance, aimed specifically at optimizing 6mm and 5.56 carbines. 3D printed from 718 Inconel, the NOAH 718 can handle high rates of fire from barrels as short as 8” in ARC or 5.56. The NOAH is also designed to work on other high-pressure rounds like 6 Creedmoor, 6GT, and other precision 6mm cartridges.
The NOAH 718 will bring down the decibels on your favorite gas carbine, no matter how hard you run it. Whether you’re shooting mag after mag in a tactical class, ringing steel at 1000 yards, or hitting the hunting woods, the CAT NOAH is a great upgrade to your rifle. CAT’s SURGE BYPASS technology keeps the gas going forward instead of back into your face, providing a better, cleaner shooting experience. That same tech also helps your gas guns run more reliably, without the need for tuning or tinkering.
Features & Benefits
3D printed 718 Inconel makes the NOAH durable, suppressing 5.56 and 6ARC rifles down to 8” barrels, but it is also compact at just over 6” long. The low back pressure will keep your guns running smoothly and quietly; ring steel, not your ears.
Featuring the industry standard 1.375x24 HUB mount, you can customize your NOAH 718 with any QD or direct thread mounts you prefer. It comes with a 5/8x24 direct thread mount in the box, so your 6mm rifle will be range ready!
