10/10 for this whisper pickle, worked great on 300blk and .260
Calvin F –
Otter creek labs hits another home run. Sounds better and is less gassy than other cans that come in at a much higher price point(even at a high rate of fire). Fantastic results on both 5.56 and .308. Great can for use on multiple guns/calibers when combined with HUB compatible mount of your preference.
Maxwell D –
This can is ridiculously good, especially at the 500ish dollar mark.
When I first started dabbling in suppressors, I had a lot of friends with other brands 30 caliber cans that were used on 556 rifles. It was fun, but, underwhelming. I bought a different company’s 556 K can. It was better sounding than other 30 cal cans on 556. It even sounded similar to Surefire RC2’s, both 556 and 30 caliber.
Enter the Polo-30, the otter creek team is very up front that the Polo-30 is not a top performer on 556. However, to my ear, this suppressor destroyed my 556 K can. Which means, this sounds better on 556 than other, including surefire’s, 30 caliber offerings when on 556.
It also makes 308 supersonic pleasant without ears on for around 6-9 rounds, with a 20” 308 bolt action.
I should have skipped the competition and gone straight to OCL. You will not regret it.

2 words love it
Ethan T –
Polo 30 is my first can and I couldn’t be happier. Compared to lahar 30, nomad, etc the lahar is a great balance of cost, weight, durability, sound suppression, and gas. Running this with a hub and plan B Setup on .308 and .300 BLK, incredible on both.
Troy Wininger –
Short, light, and heavy duty. I found the noise reduction to be adequate as well. It did change the point of impact on my rifle but stays zeroed once corrected.
Serhiy M –
Looks nice on Blackout 300 and works pretty good
William K –
Works as advertised. I used with 300 Whisper and produced 97 decibels, no more than a decent yell, very comfortable. Only issue was that box did not come with installation pamphlet. Contacted manufacturer and they emailed me a copy
Zach D –
Bought this as a general use can and it sounds fantastic. On par with my polo k sound wise on 556 and better than some of my other dedicated 556 cans while still having 30 cal capability.
Joshua N –
Good sound. Decent weight for it’s size. Built like a tank
Nicholas G –
Love the weight and quality
Jake Landphier –
Using this on a practice .308 win rifle and it’s much better than the Sandman S it replaced in terms of sound suppression and felt recoil. Nomad 30 does a little better but I bought the OCL to beat on at the range. Hasn’t affected consistency on target.
Blaze B –
awesome customer service very responsive when contacted about a hiccup I had with trust paperwork.
Zekel T –
Sounds amazing on 556 and even better on 300 blk. Outperforms cans more than 2x its price! If your not looking for an L can I would get this for sure!
Joshua H –
Can works great, lost a star for first round flash at night with 308 ar10. If nvg use is on your list it’s something to consider. Turns my ar10 into something hearing safe for a few rounds. Well worth the money.
David Letkeman –
Affordable, durable and performs much better than I expected
Michael B –
Outstanding Performance and versatility !
Andrew D –
The folks at Otter Creek Labs have cracked the code by delivering a top shelf product for a very reasonable price. The Polonium 30 is by far the best value in the 30 caliber market. The quality is second to none, and honestly, this can is quieter than my Sandman S, that was twice the price.
Chad S –
Great product an business
Todd Mitchell –
Unbelievable suppressor for an unbelievable price!
Duncan R –
Used on my 6 mm ARC AR-15 and was not too impressed. I would have liked to spend $100 or 200 more for a suppressor that was quieter.
Duey –
Love this suppressor!
Kevin R –
Very well made and very well priced.
Matthew B –
Built like a tank and handles sustained fire really well. Great tone and far prefer it to my other low cost options like YHM. Very close to on par with griffin and the cost is 200 less at the least. Very good price and product.
Sam –
Have not used it yet but I am very happy with it so far
Jason A –
Ultra high quality suppressor for a good price.
Kacy G –
For the money, the quality of this can is top tear. 10/10
Cody H –
It is good for the money
ARI R –
Great suppressor and a lot quieter than I originally expected. Great quality for price point.
Kyle K –
Best you can get under $1000
Triston A –
I ended up winning this can in a raffle, and it’s my second can. It’s not a low back pressure can by any means, but it sounds amazing. Especially with .308 subsonic ammo. This thing is built like a tank.
Holden Summers –
Great Product!
