Silencer Saturday #404: BOE Mod1 Review

Published: November 1st, 2025

Good afternoon, everyone, and welcome back to TFB’s Silencer Saturday, brought to you by Yankee Hill Machine, manufacturers of the new Victra-12 shotgun suppressor. This week we have a full review of the BOE Suppression Mod1 silencer. This suppressor has made several appearances in this series already, but it is now time for a standalone review.

Silencer Saturday @ TFB:

Design Overview

BOE Suppression is the silencer arm of DuraMag, a name familiar to lovers of metal magazines. I would count myself in that group and have uniformly good experiences with DuraMag products. That has not been the case with certain other competitor brands making metal mags.

This line of silencers was first unveiled at SHOT Show 2023. The Mod1 silencer has undergone some changes from that initial display model, but the final production version is very similar. Unlike many rifle silencers, which have fully welded designs, the Mod 1 is more of a kit. The serialized part is the outer tube, which is threaded at the ends. The baffle system is a monocore design and is interchangeable. Buyers can opt for 5.56, .308, .36, or .46 bore diameters, and titanium or inconel construction.

The back end of the baffle stack is threaded 1.375x24, aka HUB threading. When the Mod1 first came out, BOE did not offer any specific mounting system. There are ample options in the market, with almost every company offering some system compatible with the HUB threads. BOE now offers its own mounting solution if you want to keep the whole system in one brand.

Another interchangeable piece is the front end cap. BOE includes two end cap options, one with a solid surface and one with forward-facing vents. The vented option will (obviously) allow more gas to escape from the muzzle side rather than venting back into the receiver. Nothing comes for free, and venting more gas means more noise and flash.

One benefit of this design that I have (thankfully) not needed is the replaceability of components. Accidents happen. Projectiles sometimes fail inside the silencer, sending fragments into the baffles and tube. Because BOE uses a modular design, replacing parts is easier than working on a welded design. This also protects the tube, which is the serialized component, making it less likely to be destroyed in an accident.

On The Range

As far as sound performance, I would rank it as very good. Testing by PEW Science backs that impression up. The test sample in that report used the 5.56 core and closed endcap to produce very good results at the muzzle and moderate results at the ear. Jay noted that the vented end cap would improve the ear rating, and my anecdotal use of both lines up with that.

With my testing system being my non-scientific-but-exposed-to-lots-of-silencers ears, it is a silencer that I like to use. As I have moved from gun to gun, my impression has always been “yeah, that sounds good.” My initial outings were with bolt action rifles, and the performance was fine, but it really started to shine on other hosts.

But where the Mod1 really proves to be special is in its performance on semi-automatic guns. The most noticeable thing about the Mod1 is how little I notice it. The gun cycles pretty close to how it would unsuppressed, but quieter and with less recoil. Perhaps it is the emotional scars from shooting old, very gassy silencers on ARs for too many years, but being able to toss a can on a rifle and have it just work the same as it did without the can is a revelation. The Mod1 design is very effective at cutting noise while not messing with the way the host gun operates. This has opened the door to suppressing some guns in my collection that are poor suppressor hosts. Stay tuned for a whole article on just that topic.

BOE coats the Mod1 with D360, which has the following description on the product page:

“The D360™ coating process is designed to improve the durability and serviceability of BOE suppressors. This multi-stage coating provides comprehensive coverage of both internal and external surfaces unlike other suppressors. The D360™ coating significantly reduces internal surface erosion and features strong carbon-phobic properties to minimize carbon buildup.”

Without technical examination or scientific tools that I don’t have or know how to use, I can’t fully validate those claims. Subjectively, it does seem to work that way. The carbon buildup is consistently less than I would expect to see, and when there is carbon, it flakes off more readily. Despite this, it is still possible to get the core stuck in the outer tube with enough shooting. That happened after a recent semiauto 6.5 Creedmoor review. The silencer worked so well on the gun that it lived on there for the duration of the review, and it was already quite dirty before it began. The core did come back out with some encouragement, though, so all was well in the end. In contrast, the front endcaps have not gotten stuck, even with heavy use.

Conclusion

The BOE Mod1 is a unique silencer that offers great performance. It is not a budget option, with an MSRP of $1,300 without a mount. It is also not a small or lightweight can. But that size and volume, combined with the unique monocore baffle system, produce solid sound reduction. And best of all, it runs well on all kinds of hosts. This is definitely one to consider if you want to run a can on a gun that is a suboptimal or picky suppressor host. On everything from the Uzi (with the .36-caliber core and muzzle cap) to AR-10s, it has just plain worked. This is a silencer I am glad to have in my lineup for use on semiauto review guns. It tends to play nicely with everything.

Thanks for joining us for Silencer Saturday. We'll see you back here next week.
