Using spacers with suppressor to tune harmonics for accuracy

[EricE555]

Has this been done...or has it been tried and proven not to work. I have seen how the use of tuners or muzzle breaks + tuners are effective in tuning harmonics to optimize accuracy. Can this be done with a suppressor by using spacers to achieve the same affect?

How would you adjust it as tune changes, and it does? I've given this some thought and my biggest concern is bullet strike in some cases. It's gotta be moveable on the fly, imho.

I'd be VERY careful! It wouldn't be hard to change alignment and result in a baffle strike.

Possible yes
Practical probably not

I guess I don't understand the concern. Precision spacers for muzzle breaks are widely available. As long as the spacers are of uniform thickness, the suppressor will screw on straight. After all, the threads ARE concentric to the bore (or the muzzle breaks wouldn't work with spacers either).
The tuning I am talking about is not temperature or anything that dynamic. I just mean having the ability to tune the accuracy for a load by adjusting barrel harmonics till they are optimal. Moving a big weight (the suppressor) further out should have this exact effect which is what how tuners function.

I’d find a way to move the weight on the outside of the suppressor so you don’t have to worry about misalignment and baffle strikes. Oversimplifying, tape a fishing sinker to it.

But tune changes and there is not a single magical place that shoots everything great in all conditions. Kinda the point of tuner. But yes, ASSUMING everything is machined perfectly, you could do shims, like peel washers but you still need a practical way to adjust tuners. If you handload, why not just tune that way if you're not going to use the tuner for actually tuning with.

I've been pondering this as well.

On a Form 1 suppressor it seems that a protruding end cap, either forward or aft, could be threaded for a stainless tuning ring. 32 tpi should give all the tuning range you would need. Since the cap could be solid, the depth of the thread is not an issue as it would be on the tube OD.

Now the necessary weight of the ring would be something maybe Mike @gunsandgunsmithing would comment on?

I'd use about 4 ounces as minimum. and 10 max of moveable weight

10-4. I'll try that when I get my Form 1 approved.

Some shooters have been using the Sharpshooter X-Ring Barrel Deresonator for many years. I would try this approach first before adding spacers.
