Suppressors Thread shoulder or end of muzzle???

[bronson90]

What are the benefits/drawbacks to breaching the suppressor against the thread shoulder versus breaching the suppressor against the end of muzzle?

Thanks in advance; any and all educated feedback will be greatly appreciated!!!

My vote is to have the suppressor to be in tight contact with the shoulder if it is raised and cut perpendicular to the bore. On the other hand, either one could be ok if the muzzle/shoulder are perpendicular to the bore. You may want to check your can, because there may not be a surface on the inside of the suppressor for the muzzle to bear against. If it does bear on the muzzle, make sure it will not damage the crown when installed/reinstalled. make sure that you check the baffle/bore clearance before you load the gun.

The end of your muzzle should never touch the inside of your can. You want it mating up tight to the shoulder of the barrel. You have a blast baffle for a reason and most cans rely on that baffle to protect the others from improper wear and tear. A knowledgeable gunsmith will tell you the same thing. Must thread jobs for a can or muzzle device are .5-.6 inches in length. Do not go over that unless your suppressor specs say to.

In most cases either will work.

The shoulder is typically the intended surface, but due to the variety of thread dimensions on the market, there are plenty of mounts especially indexing on the muzzle out there, and some mounts are designed to mate on both simultaneously (an ideal situation that is kind of utopian when you realize how unlikely that is to occur in the real world).

The most important step in any suppressor installation is checking alignment visually prior to firing the weapon. As long as you do that, you won't have problems.

You didn't really give any idea of what you're trying to do here and that will make a difference.
If you are building a suppressor for something that doesn't have enough diameter to have a decent shoulder than using the muzzle as a stabilizing surface might be the only possibility. It works but is not the first choice for most. It would require squaring off the muzzle to insure it was perpendicular to the bore. If the crown is done properly the muzzle work and can won't affect it.

If you are buying a can and trying to figure out what to do with the barrel than using a shoulder is a better idea as it gives a larger diameter and therefore stiffer and more solid mounting surface against which to stabilize the can. It will also make it much simpler to find a suppressor since most makers don't have any sort of internal surface against which to mount.

Hope that helps.


Also, breaching is what you do when you need to get through a wall, door or other obstruction. Breech is the back end of a barrel. Maybe you don't need mr spellcheck but it makes it easier to understand if you use the right terms.
