The 8.6 Blackout has become one of the most popular suppressed cartridges in recent years. It delivers serious power in a short, controllable package, especially when running subsonic loads. But finding the right suppressor for it can be tricky. Many dedicated 8.6 cans are either too big, too heavy, or overkill for the cartridge’s actual needs.
Enter the BANISH 338.
Originally designed as a compact, lightweight .338 Lapua suppressor, the BANISH 338 has gained a strong following among 8.6 Blackout shooters. But is it actually worth using on an 8.6 BLK? Let’s break it down.

Quick Specs on the BANISH 338
- Length: 9.1 inches
- Weight: 17.5 oz
- Diameter: 1.54 inches
- Construction: Titanium with Inconel blast baffle
- Mount: Direct thread (5/8×24)
- Sound Reduction: ~33 dB (per manufacturer testing)

At just 17.5 ounces, it’s remarkably light for something that can handle full-power .338 Lapua. That same lightweight design makes it very appealing on an 8.6 Blackout rifle or short-barreled upper.
How the BANISH 338 Performs on 8.6 Blackout
Sound Suppression
The BANISH 338 does an excellent job on 8.6 Blackout, especially with subsonic ammunition. While the official 33 dB rating comes from .338 Lapua testing, many users report it performs even better on 8.6 BLK due to the cartridge’s lower pressure and gas volume. You get a deep, pleasant tone rather than a sharp crack, and it makes the 8.6 feel much more civilized at the range.
Recoil Reduction
One of the biggest advantages. The BANISH 338 noticeably tames the already manageable recoil of 8.6 Blackout. Many shooters say it turns an 8.6 into an even softer-shooting round, which is great for rapid follow-ups or new shooters.
Weight & Handling
This is where the BANISH 338 really shines. At under 18 ounces, it doesn’t make your rifle feel front-heavy like some larger dedicated .30 or .338 cans. It’s a great match for short-barreled 8.6 builds or anyone who wants to keep their setup maneuverable.
Point of Impact Shift
The included accuracy baffle helps keep POI shift minimal — an important feature if you’re using your 8.6 for hunting or precision work.
Pros of Running the BANISH 338 on 8.6 Blackout
- Very lightweight for the performance level
- Excellent sound suppression on subsonic 8.6 loads
- Noticeable recoil reduction
- Compact size (great for short-barreled rifles)
- Multi-caliber versatility (you can also run it on .308, 6.5 Creedmoor, .338 Lapua, etc.)
- User-serviceable design
- Strong build quality with Inconel blast baffle
Potential Downsides
- It’s a direct thread suppressor only (no quick-detach mount included)
- Slightly overbuilt for 8.6 Blackout if you only ever plan to shoot this one cartridge
- Some dedicated 8.6 suppressors might edge it out in pure sound reduction on subsonic ammo (though few match its weight)
Who Should Get the BANISH 338 for 8.6 Blackout?
Yes, it’s worth it if:
- You want one suppressor that can handle both 8.6 Blackout and bigger cartridges (.308, 6.5 CM, or even .338 Lapua)
- You value low weight and compact size
- You shoot a mix of subsonic and supersonic 8.6 ammo
- You like the idea of a user-serviceable can with a lifetime warranty
You might want to look elsewhere if:
- You only shoot 8.6 Blackout and want the absolute quietest dedicated can possible
- You prefer a quick-detach mounting system
Final Verdict
For most 8.6 Blackout users, especially those who value light weight, versatility, and solid all-around performance, the BANISH 338 is an excellent choice. It’s not the absolute quietest 8.6-specific suppressor on the market, but it’s one of the best-balanced options when you consider weight, size, recoil reduction, and multi-caliber capability.
If you already own (or plan to own) other rifles in .308 or larger, the BANISH 338 becomes even more compelling as a “do-it-all” suppressor.
