Re: Barrett 50bmg suppressor
Snide, hardly. Completely baffled (no pun intended,) absolutely. Wanting to make sure you plug up? You bet.
Now if we set aside all the psycho babel for a moment, perhaps you too can understand why there are so very few suppressors with anything past the end cap. After all suppression has been around a loooong time and adding a brake would have been done literally decades ago..and wasn't. Why? Because a well designed suppressor has no energy of consequence left to do anything with at that very point that these folks are putting on a brake.
Think of it this way. The whole reason a suppressor works is because the internals are able to strip away the powerful gas jets that are right behind the projectile. These are the very same gas jets that, in an unsuppressed rifle, when they finally break out from behind the bullet at the crown, creates the vast majority of all firearm noise, the BLAST. The idea behind all of what we know in suppression? By using baffles, ablatives, redirects and chambers one strips those very same gasses off from behind the bullet, redirects them, slows them and allows all that resulting energy (in the form of heat) to dwell long enough inside the can that if and when those gasses do make it out the end cap <span style="font-weight: bold"><span style="text-decoration: underline">they have little to NO energy</span></span>. No energy at the end of the can, remember that.
How does an <span style="font-style: italic"><span style="text-decoration: underline">effective</span></span> brake work? It needs considerable energy and a design that is "efficient." Efficient in this case means that the tolerances held within the brake can once again strip off those very same gasses and send them in a direction felt by the designer to cancel out recoil.

So why did that quote from the builder make absolutely no sense (except in one exception that we will cover)? Because THAT 50 cal design suggests that it has so much energy still left coming out of the can that it can be tapped in a final stage and make a difference in braking a .50. If it does, then plug up ahdra as that can is going to be loud, by design! You can have one or the other...suppression or braking (braking outside the can as all cans have some "braking" effect.) Besides the bullet mass effect I spoke about in the second link above is what makes the .50 recoil with a suppressor on and it is not going away with a post can brake.
Now I mentioned an exception. In some full auto designs, mostly all .223, a very well designed can used in a heavy fire schedule can be "over run." What that means is that the internal temperature inside the can rises to the point where those stripped gas jets can no longer find the means to slow down, dwell, dump heat. When that happens the suppression goes to hell in a handbasket and those gas jets come screaming out the end of the can. In tactical situations, full auto suppressor designers know that every can (with the exception of liquid cooled, yes they exist), if used hard enough will be over run. In the .223 FA's it is to be expected. So what do some designers do? Add a brake at the end? No....nobody adds a brake, they add a flash hider. The hider allows the operator in some situations to at least have some clandestine advantage. Your can has a brake design, not a flash hider design. And....in the .50...with all we know about suppression...that may be why you don't hear/read too much about this can.
Current can with "over run" flash suppression:

So why my response after taking the time to follow your original link, read the materials and report back? Well, aside from not realizing the importance of this can to you, personally. My response was....ahdra, plug up on every round. I would also tell you that a great .50 suppressor is quieter than an unsupressed .22lr. As you are new to the Hide (and did much better than I did on my first post...I was banned) I hope you relax and enjoy the give-n-take around here. Welcome to the Hide, nice to see you again.
