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

This will increase your OAL by only 0.375", so it will NOT get you to a California OAL legal 30"+.

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 M4 Style Fake Silencer for FN PS90

The above photos shows the MFI M4 Fake Silencer for the Fabrique Nationale FNH USA PS-90.

MFI has produced a legal version of the M4 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. The only areas where we deviate from the original in, is that the Depth of the holes are deeper to reduce weight and add a greater 3D effect and the lettering is changed slightly so as not to violate Knights Armament Intellectual Property Rights.

No FFL needed, No Special License, No Permit Required & No Special Tax Stamp needed to order.

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.

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.

The PS-90 M4 Fake Silencer slides over your barrel and is held on by 4 nylon tipped set screws. The nylon tipped set screws will not dent your barrel as much as the steel tipped set screws do. This is High Temperature Nylon so they will NOT melt. If you want steel tipped set screws all you have to do is pull the nylon tips off.

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.

You can index / position the area without holes 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.

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.

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.
