Last week I made a quick trek to Salt Lake City, UT to see and shoot SilencerCo’s newest release, the Harvest EVO. “Evolution” is a theme and a goal for SilencerCo moving forward, and this major update to the Harvester 300, a SilencerCo mainstay since 2013, is the first glimpse into what this might mean for the product line.
A lightweight, compact silencer, the Harvest EVO is intended for hunting and precision rifle use. In fact, it was originally designed for one of those three-letter federal agencies for their own…uh…precision rifles. An RFQ that SilencerCo won, by the way, with a nearly-identical variant of the commercial Harvester EVO (a different, dedicated mount on the .gov one).
Despite being shorter and lighter, the Harvester EVO is slightly quieter than the Harvester 300 it is replacing. It has a very deep, pleasing tone to it.
Despite shipping with included 5/8×24 and 1/2×28 direct thread mounts, the Harvester EVO is hitting the market at an MSRP nearly $50 lower than that of the Harvester 300, which did not include a mount. Additionally, the EVO is threaded in the now-near-universal 1.375×24 thread pitch at its base, which makes it compatible with SilencerCo’s Bravo line of mounts as well as with many dozens of mounts from a few dozen other companies.
Unfortunately I only shot the Harvester EVO indoors, which is always an absolute worst case for suppressor testing as all of the reflected noise makes it sound far, far louder than it does outdoors. On the plus side, Park City Gun Club‘s range has modern, sound-insulating fiber and rubber wall padding and a rubber (rather than steel) backstop, so it’s a fairly best-case indoor range scenario.
We shot the Harvester EVO on two shorty 300 Blackouts — an 8.3″ AR-15 built on a SilencerCo upper and lower receiver and a 9″ Black Collar Arms Pork Sword Pistol — and full-length 6.5 Creedmoor and .308 Winchester rifles.
Most apparent, especially on the full power cartridges, was the Harvester EVO’s deep, clean tone. It had no “ping” to it and extremely minimal high-pitch sound. This is typically more pleasing to the ear and subjectively sounds quieter to most people when compared to the same dB level at a higher pitch. The EVO sounds solid.
On volume level, again, indoor shooting really isn’t “fair” but I was surprised at just how comfortable the subsonic 300 Blackout was. Not just comfortable, but quiet. Darn quiet. I’ve shot subsonic 300 BLK, subsonic 9mm, and subsonic .22 LR (among others) indoors before and none of it is pleasant due, usually, to reflected sound off the backstop and/or the bullet’s impact into the backstop. All that rubber at Park City Gun Club helped for sure, and the Harvest EVO on these 300 BLK shorties sounded fantastic.
Over to 6.5 Creedmoor and .308 Winchester, I fired a couple rounds of Creedmoor without ear pro and the tone was good but with all that supersonic crack and extra powder it was a bit too much for indoor use and was right on the edge of being uncomfortable. Which, for the record, means it’s a very impressively quiet suppressor, because it would normally be full-on painful. I only attempted this because of how dang quiet the EVO was on the 300 BLK and because of how quiet the 6.5 CM and .308 sounded with hearing pro on.
I’ll borrow one from Silencer Shop when able and will put it through the normal, outdoor testing. For now, it’s just a hands-on but I have to say I’m impressed with the Harvester EVO’s performance, especially given its 6.24-inch length and 10.6-ounce weight.

SilencerCo Releases New Harvester EVO Lightweight Suppressor
December 14, 2021 — West Valley City, UT — SilencerCo is excited to introduce the Harvester EVO, a lightweight suppressor designed for hunters and precision shooters. This product is the successor to SilencerCo’s Harvester 300, enhanced to include a few key features and currently available at SilencerCo Retailers.
Accommodating calibers ranging from .223 REM to .300 WIN, the Harvester EVO is the ideal suppressor for .30 caliber bolt-guns and rifles. Consumer feedback on the previous Harvester models led SilencerCo engineers to make the EVO shorter, lighter, more affordable and ready to go right out of the box.
“The most impressive phenomenon of the Harvester EVO is it’s lightweight nature despite being created from rugged, hard-use materials,” said SilencerCo Senior Product Development Specialist, Dewie Vieira. “Weighing just 10.8 ounces, it is constructed of 17-4 heat treated stainless steel, inconel and cobalt 6 with a tubeless design. This gives the EVO an edge over other hunting suppressors.”
Not only is the Harvester EVO less likely to get caught on bushes and brush in outdoor environments, but it is capable of withstanding the most extreme conditions typically encountered by hunters and precision shooters.
