I submitted my Form 1 to the ATF and in 3 weeks, they sent me my tax stamp allowing me to install the short barrel. I use Silencer Shop (as I explained in the video) to submit my form electronically since they have everything on file. Once I had the ATF approval, I purchased the barrel and the front threaded adapter which allows the use of a muzzle device or suppressor. Now it's only 19" overall length and the way it was designed to be. There's only about 50-100 fps lost from the 16" barrel and it's still coming out at over 2,100fps. Here's' the 2 suppressors I showed in the video:
1) Silencer Co. Sparrow
2) Sig Sauer SRD22X
Both are rated for the 5.7 round. Thanks for watching!

    In a lot of the PS90 reviews they talk about putting a strip of velcro on the side of the trigger casing that faces the ejection port to prevent it from getting dinged up. Have you done that on yours yet? I just got my PS90 and I am waiting on my tax stamp to install a CMMG barrel, but going through the laundry list of chores that need to be completed. Just curious if you have any insight into what kind of velcro, etc. Irritating thing is that whenever they show their trigger box it never has velcro on it, so I almost suspect it is a myth. :)

    Hey Brother, How did your ps90 work with the SRD22X ? I am ready to sbr my ps 90 What did you put on your paperwork for barrel length?. I'm not buying a new barrel I'm cutting and threading the original. Thanks.

    If you’re going from 16 inch barrel to a 10.4 aren’t you losing more than 100 fps? I’d really like to see the ballistics on that. Just curious is all.
  • @m0cho
    Do you need a spacer with the suppressor for the exposed threads, or is it just optional ?
  • @marcv9293
    You only took 3 weeks?? I still haven't gotten my tax stamp back. how do I check the status?
  • @gangstalove2295
    Could you drop a video doing it? I have a ps90 and this 16" barrel is disgusting
