Good afternoon, everyone, and welcome back to TFB’s Silencer Saturday, brought to you by Yankee Hill Machine, manufacturer of the new Victra 20-gauge shotgun suppressor. This week we have a review of the BOE suppression IncoLite silencers, or to be more precise, the two shorter members of that three-silencer family. These are very unique silencers with their uncommon combination of lightweight design and Inconel construction.

This review focuses on the two smallest members of the family, the IncoLite 9 and IncoLite 9S.Let's start with the initial feature that everyone notices on the IncoLite series, which is the weight, or more accurately, the lack of weight. These are incredibly lightweight silencers, with the short model weighing in at just 4 ounces and the standard model weighing in at 6.5 ounces. Inconel is not generally considered a lightweight silencer material. Typically, designs that are chasing that lightweight descriptor make extensive use of either titanium or aluminum, depending on the intended calibers to be used. Inconel is more often found in very hard-use silencers, such as those intended for short-barrel carbines or belt-fed machine guns. While Inconel is not a material you are likely to encounter in many other applications in your day-to-day life, it has a solid track record in the silencer space for that type of application.What BOE has managed to do with these silencers is harness the durability that Inconel offers while keeping the weight profile low. They manage this through careful design and application of additive manufacturing processes. This is a printed can rather than a machined one so it has an alien-looking internal structure rather than the old stack of baffle cups seen in silencers 20 years ago. The precision of this manufacturing technique allows for just enough material to be where it needs to be for optimal strength without adding any unnecessary weight. I remember being shocked the first time I picked up one of these silencers at SHOT Show because I assumed it was titanium, but these silencers manage to be even lighter than certain competitors with traditional titanium designs. BOE advertises a reduced first-round pop with these silencers. I am not a scientific testing lab, but it has been my subjective impression that that statement is accurate. The FRP is not completely removed but that first shot sounds a heck of a lot more like the following ones than is the case with other silencers in this class. There are three models in the IncoLite family as of writing: the standard 9 model, the shorter 9S, and the extended-length modular 9M. For this article, we will only talk about the standard and 9S models because they are true pistol-caliber cans. Their compatibility with rifle cartridges is limited to those with more pistol-like characteristics, such as 300 Blackout and 350 Legend with subsonic ammunition only. The 9M, which will have its own review in the coming days, can accept a wider range of full-power rifle cartridges. One thing I was curious to try, particularly with the 9S, was its ability to run without a Nielsen device. This silencer ships with a standard 1/2 x 28 threaded fitting rather than the spring-loaded booster assemblies often found in semi-automatic handgun silencers. That booster assembly allows a tilting-barrel firearm to cycle properly despite the added mass of a silencer being attached to the muzzle. Some silencers are lightweight enough that they do not require a booster to function. Whether or not a booster is needed is extremely specific, gun to gun and load to load. Unfortunately, my trusty old Gen 4 Glock 19 with a SilencerCo threaded barrel did not cycle with the 9S attached, regardless of the ammunition type used. One setup that ran flawlessly with both of these silencers was my Beretta Model 84 in .380 Auto with an Allegheny Arms threaded barrel. These silencers felt very at home on that classy little pistol. This Beretta design has a fixed barrel and unlocked breech and it tends to spit gas and powder back into the shooter's face, regardless of the silencer used. That was true with the IncoLite silencers as well, though the back pressure did seem to be reduced compared to more traditional designs. That may be a virtue of the internal geometry of the IncoLite silencers or it may be a function of having more internal volume from that geometry. It was a little better than some silencers I have tried on this gun. But the gun that has seen the most time with the IncoLite silencers is the Military Armament Corp. MAC-5, which is also currently undergoing review. I have had a blast shooting that gun in a variety of configurations but one common feature has been these IncoLite silencers. The MAC-5 features a combination muzzle device with both 3-lug and 1/2x28 attachment options, so running the IncoLite was as simple as threading it onto the muzzle threads. These are such small and light silencers that they are almost unnoticeable on the front of the gun. Grabbing the IncoLite 9 or 9S when filling my range bag was almost as automatic as grabbing magazines and ammunition. The gun operated flawlessly with these silencers and the combination of the advanced silencer design and longer barrel of the MP5 both contributed to a very quiet shooting experience.Another neat feature to discuss here is the weapon light mounted on the Mac-5. It is also made by Military Armament Corp. and is marketed as the LMF. It takes the traditional flashlight handguard design that we all know and love from our favorite early-2000s action movies but adds silencer compatibility by putting just a little more space between the flashlight head and bore line. Thus far, it has accommodated any silencer I have tried, including the IncoLite family. I am not a scientific research facility so my impressions of relative silencer performance are subjective in nature, but BOE did a great job at squeezing performance out of both the size and weight categories. Another interesting trait of the IncoLite designs is that they do not heat up as quickly as other silencers in this class. I am unsure if this is a result of the internal structure and design, or of the Inconel, or maybe both, but it takes more shooting than you would expect before these silencers are too hot to touch. Again that's a subjective measure but it was noticeable.All in all, I am deeply impressed with what BOE Suppression has done with these silencers. They incorporate the benefits of Inconel without the often-associated weight penalties. They provide an excellent level of durability while not throwing off the balance of the host firearm any more than is necessary. Both of these models have an MSRP of $599 with a direct-thread 1/2x28 mount. And at that price, these are a very intriguing option.
