SILENCER SATURDAY #292: Rifle Ready Banish 46 Suppressor

Good afternoon everyone and welcome back to TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the new YHM R45 Multi-Host Suppressor. Last week the Silencer Central Banish 46 got a pistol caliber workout on a few different hosts. This week the Banish 46 suppressor goes on a rifle caliber tour with full auto 300BLK, a 5.56 bolt action, and a .45-70 Henry lever gun. Let’s dive in.

My stance is clear on rifle suppressors on centerfire rifle hosts: 1) You will need to wear hearing protection; 2) Focus on important characteristics of a quality suppressor other than noise suppression; 3) It’s going to be loud (see #1). Weight, length, back pressure (for semi-auto and full-auto hosts), and mounting options are all much more important than overall sound reduction for centerfire rifles.

However, there are two, fairly large, caveats to this stance:

Subsonic Ammunition

With subsonic ammo you are not competing with the supersonic crack of the bullet breaking the sound barrier, which can actually be the loudest noise on some host/suppressor combinations. The right ammo with the right rounds can achieve fantastic results so it may make sense to bump noise reduction back to the top of the must-haves list.

In this category, 300BLK is one of the most popular choices amongst AR-15 shooters. A nine inch 300BLK rifle is a versatile silencer host and will put a smile on the face of even the crustiest of range fudds. See my extensive list of reviews on the SIG MCX platform.

Bolt or Lever Action Hosts

SILENCER SATURDAY #292: Rifle Ready Banish 46 Suppressor

A bolt action or lever actions rifle chambered in the right caliber and outfitted with the right barrel length, will be ‘quiet adjacent’*. First, a closed action will keep all of that potential noise traveling down the barrel and out of the muzzle instead of directly into the shooter’s ear. Second, a longer barrel will allow fir a more complete burn of the powder, reducing the amount that burns outside of the muzzle which ends up just being noise and flash.

* Quiet Adjacent – Trademark pending, Pete – 2023

I am not saying that you can ditch the hearing protection – the potential for hearing damage is still high. But either, or even better – both, of these attributes will give you a chance to make a quiet shot that isn’t overpowered by either the supersonic crack or the blowback phenomenon that occurs in semiautomatic hosts.

I had low expectations for the Banish 46 with 5.56x45mm rounds, even in a bolt action rifle. The bore size is way too generous to be efficient with such a small round. It will work as a 5.56 suppressor, but it is not the best choice – much quieter but not as quiet as a smaller bored version of the Banish 46 could be.

Even though it is probably stating the obvious, full auto subsonic 300BLK is awesome. I have the Riflespeed gas block dialed all the way back so that it cycles completely, with a very low cyclic rate so it sounds and feels like an old 1919 or other classic belt-fed machine gun. The Banish 46 did a great job, as it should with all that extra length and girth. TWSS. With .30 caliber bored baffles, this would be a beast for subsonic 300BLK.

Subsonic .45-70 Gov’t is a niche round reserved for 75 yard shots on bigger game animals. These are hard cast lead rounds weighing in at 400gr. The Banish 46 did well, although in my experience subsonic .45-70 is a difficult round to suppress, leaving most suppressor options performing adequately enough to make the shot bearable but not awe inspiring.

I had a request to use a .450 Bushmaster host for this part of the Banish 46 review but I just didn’t have the time to get everything together this week. I’ll start putting a gun together for a full review on a Silencer Saturday episode later this fall.

Have a great week. Be safe, have fun, and we’ll see you back here next weekend for another Silencer Saturday.
