I mentioned a test I am doing on a .22 rimfire suppressor in this thread:


Rather than take over that thread completely I will post the update here. So far the suppressor has had 23000 rounds through it with no maintenance whatsoever.
Still going strong!

Good detail, well done..

Have you been testing the DB levels along the way??

I would be interested in a chart of DB gain in relation to wt gain.

Sadly I don't have the equipment or expertise to do it.
I have made contact with an engineer who also makes rifle components who has access to a high end sound pressure meter or whaddevayoucallit. He's the guy I will go to when I start my second batch of testing.
I have here 10 new suppressors which I will be doing sound and accuracy tests on. I am just waiting for a set of thread adapters to arrive from the US so I can test these (they are mixed threads, some are 1/2" x 20 tpi and others are 1/2" x 28 tpi).

When I test those I will add this abused one as a number 11, since I have a new A-TEC SMM4(6) as a reference.

I also have my beady little eyes on a 12g suppressor. A-TEC are releasing the A12 soon :)
