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

These are designed for LIVE FIRING.

We test all our Fake Silencers on .308 (NATO 7.62 X 51) caliber a bolt action sniper rifle (SAKO TRG 22) for accuracy / to see if there is any projectile impact deflection (less than 0.25" at 200 meters) and finally on M4 / M16 and or PKM machine-guns (500+ sustained rounds) to test stability under extreme firing, vibration and heat (no problems).

This Version of the MFI SOCOM Fake Silencer is Marked / Laser Engraved with the US. Government Property markings similar to those found on the real silencer.

The MFI SOCOM 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.

This product is "UNIVERSAL" meaning that it can be used on almost any weapon with a threaded barrel and even some weapons without threads (Requires at least 4.5" of exposed barrel with the barrel O.D. being less than 0.750").

The MFI SOCOM Style Fake Silencer can be used to do either:

  • HIDE YOUR BARREL: Hide / Cover some or all of the barrel.
  • EXTEND YOUR BARREL: Extend Barrel Length to legal 16".

MFI has produced a legal version of the 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. The only area where we deviate from the original in the lettering is changed slightly so as not to violate Knights Armament Intellectual Property Rights. Everything else is almost identical to the real thing.

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

AR10 / AR-10 Applications: Remember that most AR10 barrels have an Outer Diameter OVER 0.750" (the I.D. of the SOCOM Universal and M4 Universal), therefore you generally CANNOT hide any of an AR10 barrel unless the O.D. is @ or under 0.750". Be sure to measure as the adapters for AR10s are custom and not returnable.

One Adapter is included in the price of the Fake Silencer.

Click on the "Adapters" tab above for adapter choices.

This UNIVERSALITY is NOT Rocket Science. Everyone wants to make it more complex than it really is.

Basically the MFI M4 and SOCOM Universal Fake Silencers consist of 3 parts:

  • The Outer Body
  • The Adapter
  • Set Screws


The Outer Body is comprised of a thin outer skin that is permanently attached to an inner steel core / tube. This tube has a hole (0.750" I.D.) that runs from end to end. This diameter is a little larger than what is found on most .223 / (5.56) or 9mm caliber AR 15 barrels, which are normally @ 0.725" O.D. We originally designed these specifically for the AR-15 platform.

So the only LIMITING factor is Outer Diameter of your barrel. If your barrel's O.D is over 0.750" and you want to have the SOCOM Fake Silencer hide / slip over your barrel it can NOT be done.

If you want to EXTEND your barrel length there is NO LIMITATION at all.

What length of adapter you choose to use or whether you use an adapter at all depends on the final look that you want to achieve.


How this works is that no matter what your application is; you will receive the same outer body as you see in the above photos. All outer bodies have a 0.750" inch hole bored out from front to back.

In this hole slides your barrel and or the adapter which has a slightly less than 0.750" inch outer diameter. The inner diameter at the end nearest the front site will have a thread in it to accommodate your specific weapon (if you have a threaded barrel).

The inner diameter of the EXIT end for all adapters is 1/2 inch. So this 1/2" exit hole basically necks down the larger 3/4 inch diameter of the OUTER BODY down to a more believable exit hole for a silencer. The 0.50" hole also accommodates any caliber up to .45 ACP for safe and effective firing.

Both the outer body and adapter are finished in the same way to match 100% which give you a very clean finished look.

All outer bodies of the SOCOM have a total of 9 set screws in them that are arranged in a 3 separate cross / triangle patterns. This pattern allows you to perfectly center your barrel (important only on smaller diameter barrels like 1/2 or so). These set screws (depending on the application / adapter used) will make contact with either the adapter only (ON THREADED BARREL APPLICATIONS ONLY, if you want to screw on and off the fake silencer like a real one) or they with make contact the barrel and adapter (like on a POST-BAN assault weapon or smooth barrel of a bolt action sniper rifle.)

A 5/64 allen key is required for installation.

Set screw locations are indicated by "X" in the photo above.

Materials of construction:

The Outer Body is entirely made out of Aircraft Grade Aluminum. To keep these as LIGHT WEIGHT as possible we use similar methods of construction as the real silencers. The Outer Tubes are made from stamped plate 6061 T-6 aircraft aluminum to allow the extreme radius on the end of the tube to be formed.

The Inner Sleeve with the knurled part inside it extends from end to end thus complying with BATF in regards to NO ACCESS to the inner cavity / air gap. The Inner Sleeve is CNC machined from billet 7170 T-6 aircraft aluminum to assure lightweight and durability.

The inner sleeve and outer tube are PERMANENTLY ATTACHED together also to comply with BATF regulations. Any tampering with this item to separate the two parts will result in the tearing / destruction of the outer tube. We deliberately use very thing aluminum for the tubes so that they basically self destruct if tampered with. We deliberately did NOT use steel for the inner sleeve to keep the weight in check as well as the fact that the bullet when fired never travels through any part of the outer body so NO added durability was needed.

  • Note: Due to the weight of the SOCOM Universal & Adapter combined we do not recommend these for hand guns.

You should instead use the SOCOM MK23 style as these are 1/3 the weight of the M4 or SOCOM Universal.


1 - (One) FREE Adapter is included with this product.

Additional adapters can be purchased separately.

If you do NOT need an adapter you get a discount (Click on the "Adapters" option above) the discount is at the top of the list. Very few weapons will work without an adapter. The only example I can think of is a Post-Ban (1994 to 2004) AR-15 with a Bull Barrel (0.725" O.D.) that sticks out past the gas block at least 4.50" and does NOT have a threaded barrel.

The M4 & SOCOM Universal Fake Silencers both have a 0.750" hole that runs from end to end. They both use the same adapters. These adapters have an outer diameter of 0.745" and fit inside the outer bodies of the M4 & SOCOM Fake Silencers.

It is the adapter that makes the jump between the outer body of the Fake Silencer and the barrel of the weapon.

Adapters allow the correct spacing & thread to attach the Fake Silencer to your weapon.

The SOCOM Fake Silencer Outer Bodies have 92 holes for set screws (3 sets of 3 screws in a triangle pattern) that will make contact with either the adapter and or the barrel of your weapon. The Adapters have grooves cut around them where the set screws will make contact. The grooves in the adapter correspond with the placement of the set screws in the outer body. The grooves supply a channel that the set screws sit in for greater stability / less possible chance for slippage.

Because the Outer Body of the Fake Silencer is held in place on the adapter by set screws, you can therefore adjust / index the laser engraving on the outer body 360 degrees for perfect alignment.

Set screw locations are indicated by "X" in the photo above.

You will want to confirm the thread pattern on your weapon before ordering.



If you are NOT hiding any of the barrel and are just extending your existing barrel length you will want to a FULL LENGTH Adapter. Full Length Adapters are adapters that are the same length of the corresponding outer bodies of the fake silencers.

  • M4 Universal Fake Silencer has an OAL of 6.330", so a FULL LENGTH adapter for the M4 would be 6.330" long.
  • SOCOM Universal Fake Silencer has an OAL of 7.650" , so a FULL LENGTH adapter for the SOCOM would be 6.330" long.

Full length adapters are most commonly used on AR-15 Uppers that have 10.5" or 11" barrels; to make a legal 16" over all barrel length. Our adapters are made of weapons grade steel so they are easy to permanently attach via welding.

If you are hiding some of your barrel you will need to measure your EXPOSED Barrel Length (do NOT include any threads or flash suppressor length in the measurement). Exposed barrel is the area available to be hidden by sliding something over it in this case the outer body of the fake silencer.

On weapons like AR15s & SIG 556s the gas blocks will mark the point where to begin measuring from. Your end point is where you normally would find a Peel or Crush Washer, again do NOT include any washer, thread or flash suppressor area in the EXPOSED area measurement.

Flash Suppressors & Muzzle Brakes MUST always be removed no matter what.

Front sights on bolt action rifles or on semi-autos like M1 carbine or the M1A / M14 need to be removed in order have any exposed barrel.

The above photo shows a M4A1 / AR 15 with the SOCOM Barrel Shroud / Fake Silencer. This is a fade showing the SOCOM Outer Body slid over the existing barrel. You will see that without the adapter the fake silencer will NOT stay on.

First of all determine how much of the barrel that you want to hide and how much barrel you have available to hide.

If you have 6.15" of exposed barrel & you want to hide ALL of your barrel then you will need a 1.5" long adapter.

The math is simple… The total length of the SOCOM Universal Fake Silencer is 7.650" long. So the combined length of the area of the Exposed Barrel that you want to hide & the Adapter must equal 7.650".

The reverse is also true… If you have only 5" of exposed barrel you can NOT use a 0.70", 1.5" or 2.25" long adapters as they will be too short. The end of the adapter MUST always be flush with the end of the exit hole of the Fake Silencer's Outer Body.

Conversely if you use a M4M Full Length adapter (which is 6.325" long") in conjunction with the SOCOM outer body you will cover ALL of the M4's adapter and 1.32" of the barrel.

So get your weapon and a ruler out BEFORE you place your order.

MFI SOCOM Style Fake Silencer hiding 4.5 inches of barrel on AR15 Upper with 1.5 inch adapter

The above photo illustrates the simple math you need to use to get the exact look that you want.

In the case of the above... If you wanted to hide more of the barrel you could do that by going with a SHORTER adapter. If you want to hide LESS of the barrel you would go with a LONGER adapter.

The adapters MUST be FLUSH with the Front End of the Fake Silencer's Outer Body.
MFI M4 Style Fake Silencer adapters MUST be FLUSH with front of the fake silencer.

  1. Adapter or Barrel too short. WRONG! / INCORRECT FIT!
  2. Adapter or Barrel too long. WRONG! / INCORRECT FIT!
  3. Adapter or Barrel Flush / Even. CORRECT FIT!


Custom Adapters are available at an additional cost (Click on the "Adapters" option above) Custom Adapters are 2nd on the list. A Custom Adapter is any adapter that does NOT appear in the adapter options list. You must specify the exact total length and thread pattern (including pitch / tpi) when ordering.

I am not only amazed by just how real this looks but also by how real it feels. This product is very well made out of very high quality materials. I was so honestly impressed by the overall quality that I bought another MFI fake can (M4 Style "Blank") a week later for another AR just for a different look. I had a couple questions prior to ordering this item and I got a call back quickly and had my questions answered right away. Great customer service from MFI! I rarely give "glowing" reviews but I can say that this company knows how to make a great product and has awesome customer service! Highly recommended, you will NOT be disappointed!
