Obsidian 45 with promo kit

[wemmd]

Hi, this is my first post, and don't know that much about suppressors so your patience is appreciated. I purchased an obsidian 45 for XMAS and got the promo kit for free that allows me to use it on a 45 ACP or 9mm host. The hosts that I am considering for the suppressor is the 9mm CZ P10c and 1911 chambered in 45 ACP. The kit has a spacer and am not sure what it is for? Can anyone give me the skinny on this? Also, I am considering purchasing a modular, long range rifle chambered in 6.5 Creedmoor with a 1/2-28 threaded barrel that is compatible with the adapter in the obsidian kit but am not sure if using this suppressor for that host is a good idea?

Any suggestions are welcomed!

The spacer replaces the spring when youre using the silencer on a gun with a fixed barrel.

thank you!

The Obsidian is a pistol suppressor.

Do not use it on a centerfire rifle, it is not designed to handle those kinds of pressures and you will destroy it.

You will need to buy a rifle suppressor for use on your 6.5 Creedmoor.

I agree with ogree.

The Obsidian is a pistol caliber can.

I just looked at their webpage and there was no indication that it's rated for 6.5 creedmore.

its rated for 450 bushmaster.

.450 Bushmaster runs about 36,500 c.u.p. and Rugged probably has a barrel restriction for the .450 going through the Obsidian.

Best to call Rugged and ask.

6.5 Creedmoor runs about 61,000 c.u.p.

Big difference.

I would bet that 6.5CM has a higher muzzle pressure.

But, yeah, call rugged.

Much. Starting out with nearly twice the pressure, and it's attenuating in 1/3 the volume at any given barrel length compared to .458 cal.

The Obsidian is a good can, but with it's aluminum tube, I wouldn't chance it on a high velocity rifle.
