YES, in fact it's the number one I recommend. Almost ALL of our testing is done with one.

I'll put my Axiom up against the Gemtech in any category.

Gemtech is lighter and balances better. I know only by an ounce but that adds up at the end of the barrel.

Have you done a side buy side test using the exact same gun and ammo?

The Gemtech seems to be unavailable right now. One dealer told me Gemtech had a problem with one of their production machines and another told me Gemtech was making changes and that the can would likely to cost more when it was available again in 3 or 4 months. I find it irritating that Gemtech (and to a lesser extent their distributors) make no mention of this on their website. It is like all is well until a day or so after you try to order one. Have folks here had reliability issues with the Spectre or Axiom? I am not interested in subsonic shooting only in not having my ears bleed if I ever use it for home defense.

**I was misinformed. It is available but short supply. Gemtech told me they only do one manufacturing run for it each year. It sure is more expensive than the 5.7 rated rimfire cans but I ordered one anyway.

No trouble with my Axiom/FsN combo that isn't there when the can is off. Hoping it's just a break in issue with the new threaded barrel.

If anyone has the Gemtech around Denver, I'm up for a showdown. After that we'll put them both on my 22/45 and see how that goes.

Anyone have more info on the EliteIron Echo suppressors?I did a search on here but only found one reference to it, I was hoping for more input. They're made of steel instead of aluminum so they're heavier than Gemtechs (~2x) , they're also smaller in physical size. Does anyone know for certain if they are they as quiet or close to Gemtechs?
Gem-Tech's & Elite Iron's website do cite dB reduction ratings
GT: 32 dB
EI: 33/37 dB (high velocity/subsonic)
So it would seem they're a little better :ponder:

Other things to ponder:
EI can also be disassembled, GT cannot.
GT can be used on both FsN & PS90, EI cannot.
Contrary to popular belief, you CAN fix stupid - it's just illegal.

I realize that I am jumping in to this thread a year and a half late, but I have a question based on my recent experience with my SBR’d PS90. I installed a couple of different SilencerCo suppressors on my rifle and found one that balanced suppression with size and handling qualities. I went to the range with standard velocity ammo and started to have failure to feed issues about 35-40 rounds into the magazines. It would not fully chamber and required me to cycle the bolt to fire 3-5 shots without a hang up. The rifle shot decent groups throughout the 100-150 total rounds I shot in the session. I field stripped the rifle when I returned to my gun room and was absolutely amazed at the amount of crud ( mostly soot) and carbon in the gun, as well as the magazines ( mostly around the rollers and feed lips). The PS90 is normally a squeaky clean (relatively) shooter that requires barely a wipe and quick bore clean between sessions. I had loose carbon falling out of the chamber and soot all the way back to the hammer pack. I have over a dozen and a half suppressors of various makes and models and caliber sizes and have rarely seen this kind of fouling in a firearm before (my sbr’d suppressed Sig MPX also ran pretty dirty). I am curious if others are experiencing this level of contamination in their rifles. Is there one particular suppressor or ammunition combo that seems to be the ticket to reduce fouling more than others?

You are getting blowback.
The case is being ejected to soon.
What ammo where you using?
Try it with some Sub Sonic ammo for the P90/SBR PS90. FYI the P90/PS90 will get dirtier when firing through a can.
