FN PS90 Barrel Replacement

[@rossscarsellato1442]

Pro tip.. take a 1/8 inch piece of aluminum and put it through the flash hider, than vice down the flash hider and unscrew it. Also, take a 16" 1/2 dowel and replace the barrel with it as you take the barrel out, than put in your new barrel and push the dowel out. Makes it much easier.

This is one of the better videos I've seen, needs more views and interaction.

Love How You added in Stargate at the end!!! 😂

[@mr_5lade]

Thanks brother! I had forgotten where the front barrel spring went.

[@pororopa]

hey, do you know what the front spring is for? does it have to be there

[@mr_5lade]

@@pororopa yes, it was added so the barrel has a little bit of back and forth movement to help the firearm to cycle correctly. It does need to be there.

[@pororopa]

@@mr_5lade got it make sense, appreciate the answer!

Great video. I have no plans of keeping the old shroud or barrel after swapping for the CMMG short one. Should I cut all the way though the shroud and/or barrel above, below or right at the pin? Or if scrapping both, below the pin would work? TIA!

[@SevenStarMountain-X7]

I cut right at the pin. I you're not going to keep it, you can sell the barrel to recoup the cost of the new one. Tons of people want the original barrel but cut down, and apparently they sell well. Which reminds me I need to put mine up for sale.

[@bluedart5433]

So you cut all the way through at the pin, correct? Looks like you got frustrated by pin.

[@johnpayne1057]

@@SevenStarMountain-X7 I’m thinking of doing this process as well, but where would you put the barrel up for sale?? Very new to this, thanks for the great video! I plan on giving this a shot in a little

[@HenryRodriguez-vq1ee]

How is reliabilty woth the swap? I gather there was a janky way to do this before cmmg came out with the barrel and there were a lot of feed and ejection errors. I appreciate you did this right as you could.

[@SevenStarMountain-X7]

CMMG has been the short barrel provider for as long as I can remember. The barrels are actually manufactured by FN. It's as reliable as it was before, maybe slightly more so. The system was not engineered to have such a long barrel, so SBR PS90s tend to be more reliable.

[@icebluebear]

very clear instructions🎉

[@blackcrosser]

Thanks for the video! Is it actually possible to do this cutting the original barrel to the 10,4 inches standard length and creating a new thread for a flash hider? How the shroud actually works? I mean.. is it threaded inside? Sorry that’s not my field of work 😂

[@SevenStarMountain-X7]

Yes, you can remove the shroud and have the barrel cut down and threaded. You would need either a P90 flash hider or the CMMG adapter to keep the barrel locked in.

[@AdrenalineTheory]

Older barrels were 3 piece so you cant just drill the pin out to remove the shroud.

[@theweaponsmerchant5140]

All of them are a 2 piece shroud not a 3 piece

[@AdrenalineTheory]

​​@@theweaponsmerchant5140 Incorrect, on some of them the front flash hider part is seperatly threaded (new ones arent). Those are commonly referred to as 3 piece barrels/shrouds.

[@charlesbronson1776]

Do you need the CMMG thread adapter for their 10.4" barrel to suppress the rifle? I have their muzzle device when it's not suppressed.

[@SevenStarMountain-X7]

Yes, unless you get a suppressor that attaches to the P90 muzzle device.

[@alext6702]

Great video

[@fredericklyons4714]

Can you link that flash hider

[@SevenStarMountain-X7]

No, KZbin will not allow it. Google "silencerco single port brake."

[@elultimo102]

@@SevenStarMountain-X7 I wish Musk or Trump could buy KZbin---There would be no problems then.

Diameter of wooden dowel?

[@T.VALHÖLL]

You have to stick something in the flash hider, then stick that in a vise... Secondly, who taught you how to use a torque wrench, torque wrenches are for putting things in torque, not for removing the torque. That's how you can de-calibrate your torque wrench

I didn't watch the entire thing, but the part I did watch appears to be a how to on NOT how to do this barrel swap.

I didn't watch the entire thing, but I'll still put in my ignorant 2 cents. Thanks, Bubba!
