MFI California (Ca.) & Maryland (MD) Legal 30" OAL / FN PS90 SOCOM SASS KAC Style M110 / SR25 Fake Silencer / OAL 30" Barrel Extension / Price Includes S&H + Insurance via USPS Priority Mail

Fake Silencers are also known as: Barrel Extension, Dummy Can, Faux Suppressor, Mock Silencer, Barrel Shroud & Non Functional Sound Suppressor.

These are designed for LIVE FIRING.

We test all our Fake Silencers to be 100% sure that they function shot after shot without any problems. Be sure to see our notes on the best ammo to use with this item. Click on the TAB marked "Ammo Issues"

MFI California (Ca.) & Maryland (MD) Legal 30" OAL / FN PS90 SOCOM SASS KAC Style M110 / SR25 Fake Silencer / OAL 30" Barrel Extension.

This Version of the MFI FNH PS-90 SOCOM Fake Silencer is specifically made for the California Market to meet the CA DOJ minimum overall length of 30".

This item differs from our regular PS-90 Fake Silencers / Barrel Shrouds / Barrel Extensions in that it is longer and it is NOT Laser Engraving. So this item is "Un-Marked / BLANK..

The first photo shows the MFI California (Ca.) & Maryland (MD) Legal 30" FN PS90 SOCOM SASS KAC Style M110 / SR25 Fake Silencer / OAL 30" Barrel Extension with the QD SASS Rear Section attached. The second photo shows that this product is actually 2 parts. Once you time the shroud to where you want it to be on the PS90 you will mark the 12 o'clock position on the shroud and then remove it, in order to epoxy the rear SASS QD on. The epoxy will be the only thing holding the rear section on. The rear QD SASS is 100% cosmetic and does NOT lock to anything.

I also offer the MFI California (Ca.) & Maryland (MD) Legal 30" FN PS90 SOCOM WITHOUT the Rear QD SASS Section on this page.

Unlike our other PS-90 Barrel Shrouds this item is specifically for a VERY LIMITED MARKET and as such is made in very small volumes. Normal production for the standard PS90 fake silencer is 1000 per year minimum. This California & Maryland Legal version we have only made 50 units to test the market. So it goes without saying we have to charge more money for these. We do our best to keep the price down for our valued CA customers. Support the USA and "Buy American" and support all the California based firearms companies and "Buy from a California Dealer or Manufacturer."

This product fits ONLY the FN PS90.

MFI has produced a legal version of the M4 & SOCOM Knights Armament Silencer (to meet current BATF specifications for a Fake Silencer / Non-Functional / Cosmetic Only ) here in the USA. MFI has been a Class II BAFT 07 Manufacturer + SOT & a DOD / Military Contractor so we have access to the real thing here to take measurements off of to assure as close a match as possible.

All MFI Barrel Shrouds / Fake Silencer / Mock Suppressors / Faux Silencers are 100% Cosmetic & have ZERO Function. Unlike true vented barrel shrouds / heat shields our products make NO CLAIM to any protection from heat that is generated from the barrel. As you fire, your barrel will heat up and that heat is directly transferred to the MFI Product. Therefore you should NEVER grab hold of the MFI Product if you have fired more than 5 rounds, as you WILL burn your hands.

The MFI M4 & SOCOM Style Fake Silencers do NOT reduce muzzle noise or muzzle flash in any way. So these are to the best of our knowledge 100% legal for the regular civilian to own in all 50 US States.

Obviously it would be impossible for any manufacturer to know every law / regulation / ordinance of every Country, State, County, City or Town on the planet. For this reason you the customer are required to research this issue to be sure you are within the laws of your specific location.

MFI is NOT liable for any item purchased that violates any law(s) or regulation(s) anywhere on the planet.

One would think that common sense would be a good guide line for any issue, but as the US Federal Government lacks any sense of this we are forced to make statements like this.

When MFI is informed of a State's, County's, City's or Town's specific law / regulation / ordinance we will post it here for all to see. We require a copy of the exact wording to verify the validity of the claim.

  • Patented Design.
  • 100% Made in the USA!
  • Designed for LIVE FIRE.
  • The main body is made of 6061-T6 AIRCRAFT GRADE ALUMINUM.
  • Precision CNC machined from billet.
  • Fits only FN PS 90.
  • Maximum Outer Diameter: = 33.0mm or 1.300 inches.
  • Maximum Length: = 289.67mm or 11.404 inches.
  • Weight: 15.8 ounces!
  • Mil. Spec. Acid Etched (anti-glare)
  • Mil. Spec. Anodized to give the unit a semi flat finish.
  • Comes with: 4 Steel Tipped Set Screws #8-32 X 1/4" long. NOTE: The nylon tipped set screws I carry will NOT fit this product as they are too long. You can find them on eBay or Amazon.
  • You can index the can any where you like as the rotation of the outer body is stabilized / stopped by the set screws that makes contact with the hidden barrel.

NOTICE: Nylon Tipped Set Screws. While I prefer having a steel on steel connection when it comes to set screws, I understand that 99% of those who purchase this item do not want to leave too much of a mark on the barrel. The only way to accommodate this is with High Temperature Resistance Nylon Tipped Set Screws. Set screws regardless of the material can back out due to vibration, so they should be checked from time to time.

  • I am NOT supplying or even carrying Nylon Tipped Set Screws that would fit this product for the following reasons:
  • Supply Chain Problems with Availability.
  • Nylon Tipped Set Screws have become stupid expensive.
  • The Nylon Tipped Set Screws I carry for the M4 are too long to use on the new SOCOM cans as they stick out.
  • They are 100% available on eBay for stupid money if you have to have them. Look for 8-32 in a total length no longer then 5/16.
  • Nylon Tipped Set Screws can slip as they are not as secure as a pointed steel tipped set screw.

The MFI M4 Style Fake Silencer does NOT reduce muzzle noise or muzzle flash in any way. So these are 100% legal for the regular civilian to own in all 50 US States.

The PS-90 M4 Fake Silencer / Barrel Shroud fits the FNH PS 90 Carbines WITHOUT ANY MODIFICATION.

This accessory does NOT affect the accuracy of the weapon in any way.

Sliding anything over your barrel or using any type of set screw WILL leave a mark. If your are worried about marking or scratching your barrel, this product is NOT for you.

No FFL needed, No Special License, No Permit , No Proof of Age & No Special Tax Stamp needed to order.


In accordance with the Joe Biden & Beto O’Rourke directive I personally as well my company no longer own(s) or possess any firearms or ammunition all lost in a terrible boating accident. This includes, but is not limited to: Handguns, Pistols, Shotguns, Rifles, NFA items, Hog Legs, Fire Sticks, Smoke Poles, WMDs, Alien Death Rays, Phasers, Lasers, Storm Trooper Blasters, Directed Energy Weapons, Nukes and or Thunder Clubs.

So, I no longer need the US Government's gracious and altruistic offer to buy back any weapons "real, imaginary or things that might identify themselves as weapons" for their "HEAP BIG WAMPUM"!

All firearms that appear on our web site, regardless of what is written about them, are not owned by the company nor possessed by anyone associated with MFI and may even be AI / CGI / PhotoShop.

Therefore regardless of any new firearms laws / taxes, no probable cause can EVER be assumed on any property (stationary or mobile) owed by myself or MFI.

AGAIN: We are 100% in compliance with any possible new “Biden / O’Rourke Public Safety Act” and therefore NO PROBABLE CAUSE could ever be assumed.

Lastly anyone arriving with a warrant of any kind will be assumed to be an IMPOSTER with intent on murdering us and will be treated as such without warning.

Those invading our territory may receive serious and even fatal wounds from rusty blades, clubs with bent nails, spear tips, arrows, crossbow bolts and or Big Mike's man member.


States in IL & NY have recently defied the Supreme Count's Rules and continue to enact new gun laws.

TO BE 100% CLEAR! MFI (in essence me as I am a one man show) having studied Constitutional Law in Collage see ALL STATE LAWS that limit firearms in any manner as a violation of BOTH the 2nd Amendment and the 10th Amendment.

I WILL ship ALL MFI PRODUCTS to all 50 US STATES regardless of your state's "opinion" or "feelings" or "regulations" as these are absolutely 100% Unconstitutional.

Additionally we will NEVER turn over any records of our customers to ANYONE regardless of their threats or illegitimately and illegally obtained court order.


This item is NOT RESTRICTED FOR DOMESTIC US SALES in any way and we offer DOMESTIC USA shipping to ANYONE. We ship to all 50 US States as well as all US Territories i.e. Guam & Puerto Rico. Sorry we can NOT ship to ANY APO address regardless of actual location.

This item is 100% RESTRICTED FOR EXPORT OUTSIDE THE USA. The US Department of State regulates / restricts this product and it is NOT EXPORTABLE outside the USA even to LE, Governments or Military without State Department approval.

This approval is AVAILABLE through MFI as we are an ITAR / Dept. of State Registrant with the Directorate of Defense and Trade Controls Office. We can obtain a US State Dept. Export License for you.

Please feel free to contact us if you have any questions on this issue.

Ammo Issues


Extensive testing has shown that of the 3 commercially available 5.7 ammo that the SS197 is the PREFERRED munition to use. Testing was done in late 2005 and the only available ammo was all manufactured by FN. We have NOT re-tested any ammo since, so this information is all that we have. We continue to use the FNH SS197 to present time and performance has remained the same.

The SS195 has proven to be EXCESSIVELY DIRTY and WILL cause massive fouling and carbon build up between the fake silencer and the flash suppressor of the PS90. While this is NOT dangerous to the user it does make getting the fake silencer very difficult to remove.

Even as few as 30 rounds of SS195 will result in this problem. If you use the SS195 and have this removable issue the best resolution is to remove the set screws and spray WD-40 or other lubricant into the holes or down the rear open air gap around the barrel and also down the front end in the bird cage area (use a lot) and let it run down the barrel to the PS90 Flash Suppressor. Let it sit 15 to 310 minutes and then gently work the fake silencer free. WARNING trying to remove without lubricate could result in damage to the finish of the PS 90.

The SS196 ammunition has not yet been tested. It remains unfindable at any reasonable price.

Please use the SS 197 ammunition:

We have fired over 300 rounds of the SS 197 at one time and have NOT run into any excessive carbine build up. We highly suggest that regardless of the ammunition that you choose to use that you test 15-20 rounds first and then check to see if the fake silencer moves freely or not. As you know we are not in control of what goes into any ammunition. Ammunition can vary form Lot to Lot as well. I would suggest that you clean the shroud (via removal) every 300 rounds or so.

MFI will NOT be modifying existing in stock product to allow use of the SS195.

As of 01-01-2014 we NO LONGER test any new ammunition. As of 2008 no customers have come forward with any problems with any of the new ammo, so we have concluded that the issue has always been with ONLY the SS195. We will NOT be re-testing the SS195 for any reason so suggest that you just avoid it all together.

It is pointless to test and retest all available ammo when the only issues have been with one single source and type. In short we do not want to raise the price of our product due to the cost of testing and buying ammunition when no one has come forward with any problems since 2008.

The issue has always been with the ammunition and NOT our product.

We will make changes to this page if customers alert us to any new dirty ammo on the market. Ammo to avoid will be posted here.
