Hi All,

I have a pair of Tranquilo Suppressors that I swap around on a bunch of rifles that have the tranquilo brakes on them.  Has anyone tried to use a Tranquilo on a rifle that doesn't have the LT brake on it?  I have a bolt action rifle that I'm going to order a suppressor for and was wondering if the Tranquilo would work on it.  It looks like from the documentation that the thread pitch is the same but I'm wondering how the locking collet would work.  I'd appreciate hearing anyones experience before I try this for myself.

I have run mine on multiple bolt guns as well as semis. The standard brake, 5/8 24, will thread on any standard threaded barrel. The only threading you need to lookout for is 1/2 28 that’s found on most 223/556 guns.

FWIW, Lt does make a muzzle brake specifically for bolt guns. Only difference is the mating face is flat vs shouldered. You may, or may not, want to order that one for a bolt gun.

Good luck.

Thanks for the info.  What does the locking collet do if I screw the Tranquilo suppressor onto a direct threaded barrel with no brake?

Not going to happen. I haven’t checked the threads but totally different. If you don’t use the brake you are not mounting the can.

Yeah, I just realized that.  My bolt action has 5/8x24 threads for a suppressor.  My tranquilo brake is something like 11/12" (.925) threads.  Back to the drawing board.

Just order the 308 brake.

The Tranquilo is not a direct thread can, so you cannot direct thread it.  It’s also not modular, so you can’t change out the QD setup.  Basically, there is no “drawing board.”  If you want to mount your Tranquilo to your bolt gun, you need to purchase Larue’s QD Tranquilo muzzle device.  That is your only option (outside of some serious custom work).
