Description

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 machineguns (500+ sustained rounds) to test stability under extreme firing, vibration and heat (no problems).


This Version of the MFI M4 Fake Silencer is Marked / Laser Engraved with the Navy Seal Logo.

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 M4 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".

The above photo shows a FN FS2000 with the M4 Barrel Shroud / Fake Silencer.


  1. Is a fade showing the M4 Outer Body slid over the existing barrel. You will see that without the adapter the fake silencer will NOT stay on.
  2. Is the Adapter for the FNH FS-2000. This adapter could be any length, but in this case it is just long enough to accommodate the M4 outer body. The adapter screws on to the existing barrel and the outer body slides over the adapter & the barrel and is held in place by set screws that make contact with the adapter and or the barrel.
  3. Is the end result... This same product and application can be used on AR15s, HK G3s, AK-47s, etc.


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.


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:

The Outer Body is solid and 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 M4 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.


SET SCREWS & THE ADAPTER SYSTEM:

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 have a total of 12 set screws in them that are arranged in a 3 separate cross / star 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 "White Dots" and or "Black Arrows" in the photo above.

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.

Adapters

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 M4 Fake Silencer Outer Bodies have 12 holes for set screws (3 sets of 4 screws in a cross 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 "White Dots" and or "Black Arrows" in the photo above.

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


WHAT LENGTH ADAPTER DO YOU NEED?


EXTEND YOUR BARREL LENGTH:

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.

HIDE SOME OF THE BARREL:

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.


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 7.75" of exposed barrel & you want to hide 4.825" of your barrel then you will need a 1.5" long adapter.

The math is simple… The total length of the M4 Universal Fake Silencer is 6.330" long. So the combined length of the area of the Exposed Barrel that you want to hide & the Adapter must equal 6.330".

The reverse is also true… If you have only 4" 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 SOCOM Full Length adapter (which is 7.650" long") in conjunction with the M4 outer body you will have 1.32" of the SOCOM's adapter sticking out the back end of the M4's can.

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

MFI M4 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:

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. You will write this information in the "Order Section" of the shopping cart, just below the "Payment Information" where it says "Special Request / Custom Orders".

I am a master machinist and this product is better than I could have made for myself. Plus it has a WAY COOL logo and lettering that makes this look like the real thing. I also bought 4 other adapters to move this same item form my AR15 to my HK91... the adapters are differnt lengths and give me 4 very differant looks as they cover differnt amounts of the barrel.

THANKS MFI for the Great Product...

Super Quality & Great Price!

I have to admit that when I first read about these on AR15.com I was skeptical, but it made sense as I really wanted to hide that stupid long barrel on my Colt M4 carbine. So I ordered both the NAVY SEAL and the BLANK versions, figuring I would keep the one I liked the most and just return the other one. HOLY MOLLIE! Just out of the box these were cool... then on the weapon it simply transformed it to a whole new look! I have to say that the machining is top quality and this is by far the nicest & coolest accessory I have ever bought for my AR. Now I see how they can fit on any weapon. So I ended up keeping both and I just sent my adapter back to trade for one for my FNC... With quality like this it is no wonder why MFI has such good press on the forums. I would have paid a lot more for this item, so I also feel like I got a great deal too. FREE SHIPPING & super fast turnaround time... I placed the order on Tuesday night and it was in my hands on Thursday?

AAAA++++ all the way!!!

Way better than any one elses product!

I ordered the fake suppressor for my S&W M&P15-22. I bought one of the first issues of this rifle, and it has an unthreded barrel. I always thought it looked a little plain. Rather than thread the barrel, and add a flash hider, I decided on your product.

It is a beautifully machined accessory, with a very distinctive look.

Thanks for obviously taking pride in the products you offer.

I purchased a blank M4 fake silencer for my KelTec Sub2000. My rifle has no threads; the adapter had to be bored out to .528". Not only did the adapter fit perfectly, it installed without a hitch! I took the rifle to the range and everybody was commenting on the awesome style the fake silencer gives the rifle. The viewers at thektog.org, the KelTec Owners Group website have all commented very favorably on it, also. Thank you, Michael, for a wonderful product.
