Made entirely of titanium, the lightweight Q jumbo SHRIMP is one of the few 6.5mm-specific suppressors on the market. It’s targeted toward PRS and other precision rifle style shooters plus hunters looking for a compact, lightweight can that will protect their hearing while not getting in the way.

I feel like a bit of a broken record saying this again, but as shooters become more and more experienced using suppressors they tend to gravitate away from chasing dB numbers and toward finding the least obtrusive suppressor that’s still quiet enough to be “hearing safe” (under 140 dB at the ear). Likewise, as the market matures we see manufacturers filling this niche.

Such is the case with Q’s new jumbo SHRIMP. New enough, in fact, that it isn’t even yet on Silencer Shop’s website. Keep an eye there, though, as they make the suppressor purchasing process as easy as it can possibly be, including finding a dealer near you to complete the transfer. [EDIT: it’s on there now! We updated the link]

At only 5.69 inches in length and 9.2 ounces in weight (plus 2 ounces for the Q Cherry Bomb muzzle device), the jumbo SHRIMP is one of the shortest and lightest centerfire rifle silencers available.

If maximum sound suppression is your goal, Q makes the Full Nelson (direct thread) and the Thunder Chicken (quick attach like the jumbo SHRIMP) to scratch that itch. If you want to stay hearing safe on your 6.5 Creedmoor, 6.5 Grendel, 6mm Creedmoor (or BR, etc.), .260 Rem, .243 Win, or .223 rifle (etc. etc. — anything under 6.5mm / .264 caliber in diameter) without adding any more length or weight to it than necessary, the jumbo SHRIMP just may be your huckleberry.

Q’s engineering and design experience definitely help achieve significant sound suppression in such a small package. Some notable features are the jumbo SHRIMP’s larger-than-standard 1.75-inch outer diameter, the tubeless design to maximize internal air volume, and a baffle design honed over decades of testing and refining by the Q team.

Accuracy, too, is very important for the jumbo SHRIMP’s intended application and Q ensures good results by wire EDM cutting the bore (meaning it’s perfectly concentric and consistent), which is also sized fairly generously for the caliber (the bullet doesn’t pass to closely to the baffles).

As you’re probably aware, Q loves them some tapers and they sure do use them to good effect. On the Cherry Bomb muzzle device, for instance, a taper section in front of the thread provides a complete gas seal on a matching taper inside the jumbo SHRIMP.

Not only does this keep the threads clean, but it keeps the suppressor from coming loose during use as the additional surface area and “squeeze” provided by the two interacting tapers locks up far more securely than two flat shoulders do. Even with much less torque applied to the suppressor during installation.

One warning: when installing the Cherry Bomb onto your barrel, in particular with a standard, square-shouldered barrel, make sure to use thread locker and torque the Cherry Bomb down its full spec. Because the suppressor-to-Cherry Bomb tapers seal up and grip so well, it’s easy to get into a situation where unscrewing the jumbo SHRIMP unscrews both it and the Cherry Bomb, leaving the Cherry Bomb stuck inside the can.

Without external wrench flats or any other tool interface, and designed as it is to barely protrude from the base of the suppressor, it becomes very tricky to remove. So . . . make sure it’s gripping your barrel harder than it’s gripping your suppressor.

Out on the range with a 20-inch 6.5 Creedmoor from Black Collar Arms and a 24-inch 6.5 Grendel from Precision Firearms, the jumbo SHRIMP’s performance was spot-on. It was completely comfortable to the shooter’s ears, yet is so lightweight that it doesn’t affect the balance of the firearm.

On the semi-auto there was no noticeable blowback to my face or eyes. I think the generous bore combined with the shorter length are both good things for use on a semi-auto, helping excess gas and pressure leave through the muzzle rather than the upper receiver.

Without a doubt, the jumbo SHRIMP is a fantastic choice for a precision rifle or hunting rifle firing a 6.5mm / .264 caliber or smaller projectile. However, it should be a rifle with a rifle-length barrel.

On a later range trip I installed the jumbo SHRIMP on this 12-inch 6.5 Grendel bolt action pistol and it was much too loud. Painful to the ears and I wished I hadn’t pulled the trigger. My fault for simply assuming that, as nice as it sounded on a 20-inch 6.5 Creedmoor, it would be able to handle a 12-inch barrel on the less powerful 6.5 Grendel. But, alas, it isn’t enough suppressor for a short barrel. Naturally, it wasn’t designed for that use so it’s clearly on me here, not Q.

While I think the jumbo SHRIMP is a great suppressor, I wouldn’t purchase it over Q’s other cans unless I was dedicating it to a specific rifle. It’s just too niche with its smaller bore and shorter length. For instance, a trash PANDA would be far less restrictive if I wanted to use it on multiple guns, but still wanted something pretty dang short and lightweight compared to the norm.

That said, if I were outfitting my PRS rifle or a lightweight hunting gun, the jumbo SHRIMP would be on my list of potential suppressor suitors for sure.

Ratings (out of five stars):

Utility  * * * 
A relatively niche silencer due to the 6.5mm projectile bore and the as-small-as-possible size, which means it’s only hearing safe on rifle-length barrels.

Form Factor  * * * * 
Amazingly compact and lightweight. Won’t get in the way or weigh you down at matches or on hunts. I’m docking it a star here, because I think it’s a mistake not to design a tool interface on the Cherry Bomb that’s accessible when it’s installed in the suppressor.

Suppression  * * * *
For its size, the jumbo SHRIMP’s sound suppression chops are quite impressive. I don’t think there are a lot of suppressors on the market that could be chopped down to this length and perform this well. That said, it requires a rifle-length barrel to stay just this side of hearing safe. That, of course, is the design intention of the jumbo SHRIMP so in that they’ve succeeded.

Overall  * * * 
The jumbo SHRIMP by Q is a great suppressor for the user looking for the lightest, shortest silencer they can get for their 6.5 Creedmoor while still just coming in this side of the established hearing safe threshold. However, this makes it a narrow niche can that’s also one of the more expensive suppressors on the market at over a thousand dollars. At an appreciably lower price point I’d give the jumbo SHRIMP four stars without hesitation. It suits its focused purpose extremely well. I might give the jumbo SHRIMP five stars if, in addition to a lower price, its mount end were threaded in the 1.375×24 standard, which would give owners a huge breadth of mounting solutions from which to choose. Overall the jumbo SHRIMP is a great suppressor, I just can’t quite see purchasing it over some of Q’s other offerings.

  1. Wish we had a Db meter, showing the no suppressor and with suppressor sound levels. Even with most suppressors, the noise level is still loud for rifle rounds, and many pistol round as well. The “poof” of a suppressor in movies is all make believe!

  2. NICE – Anything over ~120 dB is considered harmful, but a drop from 164 to 138 is like going from standing next to a jet engine to a big block V8 with no muffler. Still not great for your long term hearing, but that, level (~138 dB), use of typical hearing protection means that when your grandkids talk to you, you can understand what they say.

    • For impulse sounds, OSHA claims that under 140 dB does not cause hearing damage. It’s extremely different from continuous noise levels. There’s a lot of interesting debate around all this, but it’s why 140 dB is the hearing safe threshold in the firearm industry and some of the reason the military came to the same conclusion.

    • The noise generated by a supersonic projectile is right around 140 dB. So on most rifles it’s really not worth having a huge can.

  3. Jeremy, what did you use audio-wise to record that?

    I ask because on this end, it sounded like gunshots, which is usually not the case with video recordings…

    • I have my setup set to not “clip” the microphone, which almost everything does by default. External mic without noise suppression. Nearly everything automatically tamps down loud noises and tries to keep all volume in a video consistent and normalized near the middle. I got a setup that allowed me to turn that off. Obviously it’s NOT as loud as it would be in real life or you’d need ear protection to watch a gun video playing on your computer, but it gives a better approximation.

      And a supersonic rifle round sounds like a gunshot whether it’s suppressed or not. It just does. The difference is that there’s no concussion (no “bass” to it) or blast and obviously the peak sound level is much lower. But 130 to 140 dB is still *REALLY* loud and there’s no hiding the fact that it’s a gunshot. I think about 124 dB (ish) is the max where you could shoot in proximity to “stuff” and it may very well go completely unnoticed. This sort of sound level really is not possible with supersonic ammo.

      • It sounded very good, far more natural than most videos.

        I like how in the downrange shot you can distinctly hear the bullet ‘whip’ by at impact…
