Has anyone ever opened up a 5.56 Suppressor to accommodate a bigger caliber round like 300 blk or 7.62 to make it more universal.

Changing the caliber of a suppressor constitutes making a new suppressor and requires a new $200 tax and a Form 1/4. So it's generally not something that's cost effective to do.

You know, while this is true and accurate, I've often wondered how the Courts/ATF would accommodate the enlargement of the bore diameter through wear.  The end result is the same, just the manner of arrival is different.

Going from .280" ish to .370" ish is a TON of wear

I have thought about this before. One of the reasons I don't try 300 bo is because I would have to a 7.62 Suppressor which are usually significantly heavier than 5.56 suppressor.

Tax regulations aside, the construction of the suppressor will dictate whether it can be over bored. The baffles must be keyed or welded to prevent them from spinning inside the tube. Most baffle designs allow for minimum wall thickness for their designated caliber to keep weight down, thus over boring may break the baffles. You will need a boring machine capable of traveling the entire length of the suppressor, most milling machines and lathes only have 3-4" of quill travel. Lastly you'll have to get the chips out of the suppressor this is nearly impossible if it is sealed.

The only realistic way to do it would be the way most manufacturers make them: wire EDM

A lot of valid point. Thanks for the responses.i guess it makes sense to just go buy another one. Just hate the waiting, so I'll buy one at one of my local ranges that'll let me shoot it at their range while I wait for the stamp.
