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 are taking a first look at an interesting suppressor from Savage Arms. This noted maker of bolt-action rifles has gotten into the silencer game as well, and I just received two of the two silencers from them for review. The first one we will take a look at is a reflex design known as B.O.B.Silencer Saturday @ TFB:Silencer Saturday #455: Can We Have Captive Piston Ammo Now?Silencer Saturday #454: 375 Raptor Silencer Saturday #453: NFA Sea Change In Wake Of ATF Guidance LetterSilencer Saturday #452: Silent But Deadly Subsonic Rifle Match Silencer Saturday #451: Return of the LVAW At first glance, the AccuCan 30 BOB looks like most other silencers. It is a black cylinder. There are some external textures that help with tightening it, and it looks a little wider than many silencers but it is, once again, a metal cylinder that attaches to the muzzle.The unique feature of the BOB, which made me interested in a review, is its reflex design. BOB stands for “back over barrel” because the back end of the silencer extends past the muzzle over the first few inches of barrel. This offers increased internal volume without extending the length. Reflex designs are not a new technology, and we have looked at them in the past, but seeing such a design from a big-box-type manufacturer is an interesting development.The BOB has some girth. This is necessary to provide expansion volume in the reflex portion while accommodating common barrel contours. Though it is wider than many silencers in this class, the weight is still manageable thanks to the aluminum construction and titanium thread insert.

Then cool to ambient temperatureMSRP: $999.00 USDA few other features to note: the front of the silencer includes a flash hider feature. Savage also includes a nice Armageddon Gear soft case to store the silencer in. There is also a special wrench included inside the box so the silencer can be tightened onto the host gun. I've only test-fired the BOB at this point and do not have real data to share but it did seem fairly quiet on the Savage Model 110 Predator Ultra Light in 6.5 Creedmoor. Anecdotally, I have heard from some reflex can users that a closer match between the bullet and bore diameter makes more of a difference with a reflex design than a traditional muzzle-mount silencer. The logic here makes sense: a closer fit between projectile and silencer bore will increase the "plugging" effect, which will help fill the expansion volume behind the muzzle with a smaller-diameter projectile. The route of least resistance for those gases is exiting alongside the projectile instead of being stopped up and pushed back behind the muzzle. I plan to experiment with this phenomenon to see if it is perceptible with this silencer as well. One word of caution for reflex silencers in general and the BOB in particular is around muzzle thread adapters. The 5/8-24 threads in the silencer are buried deep down inside. Use of a muzzle thread adapter is very risky because if it unthreads from the barrel, it may become trapped inside the silencer with no easy way to remove it. Wrench flats do not do much good when they are several inches down inside a tube.This could be a solvable problem, and redneck solutions (such as applying Loctite to a muzzle and screwing the adapter on to create a bond that is stronger between muzzle and adapter than adapter and silencer) would likely work to get the silencer back off. The best practice is to avoid all of that drama and just use this on the correct size muzzle threads. Here are some demo pictures of the BOB mounted on a couple of different rifles to show what it looks like on the gun: As we covered here at TFB, Savage Arms was recently purchased by Smith and Wesson. What this means for the future of Savage and its silencers is not yet clear. If I had to make a guess, I would assume that Savage continues as a bolt gun manufacturer where its name, reputation, and product lines are respected. Smith & Wesson does not currently manufacture bolt rifles, so the risk of sales cannibalization between the two companies is low if Savage stays in that lane. Gemtech Silencers is a Smith & Wesson brand, and how that will work with the Savage AccuCan family remains to be seen.Thanks for joining us for another installment of Silencer Saturday. We’ll see you back here next week.
