MFI M4 Style Fake Silencer & Adapter for Umarex HK MP5A5 / Marked / Laser Engraved NAVY SEAL

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 to be 100% sure that they function shot after shot without any problems.

This Version of the MFI Umarex / HK MP5A5 (.22 LR) M4 Fake Silencer is Marked / Laser Engraved NAVY SEAL. (Adapter Included)

This product fits ONLY the Umarex / HK MP5 A5 full length carbine it will NOT fit anything else as we have a special adapter for this weapon system.

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.

This will NOT fit the MP5 SD model.

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.


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. This includes but is not limited to: Handguns, Pistols, Shotguns, Rifles, NFA items, Hog Legs, Fire Sticks, Smoke Poles and or Thunder Clubs.

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 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 and or crossbow bolts.

Best product on the market... you will not believe the CNC quality... The Umarex cans must be made in China by slave labor as they SUCK so bad...

Perfect fit and so improves the looks.
