MFI SOCOM BLANK / Unmarked 9mm X 0.75 pitch for SIG Sauer .22 Caliber Mosquito Style Fake Silencer or 15+ Custom Threads Available

What makes the MFI SOCOM Fake Silencers (SOCOM Mosquito / Custom Thread) UNIQUE from all other real or fake silencers is:

The LETTERING / MARKINGS are INDEXABLE to the CORRECT POSITION! (Assuming you have it engraved as well) As you may not realize all threaded barrels and silencers have different starting and ending points on the threads. Thus you could have 5 identical weapons all made at the same time and the same silencer or flash suppressor will NOT end up at the same point on each weapon. This is why you get a peel washer with your AR15 flash suppressor (peels off 10 /1000th of an inch) so you can correctly index your suppressor to the individual weapon.

So what we are saying is... No matter how many weapons you have... You will ALWAYS be able to get the lettering / U.S. GOV. markings in the exact location that you want them. This is because there is a set screw is hidden in the bottom of the end cap (see the "x")that allows the outer body to rotate 360 degrees around the inner barrel. First tighten the set screw and then thread the fake silencer on your weapon. Then loosen the set screw and continue the rotation as if to tighten / go on direction... Position the Laser Markings to the correct location & re-tighten the set screw.

You can screw on & off the Fake Silencer and NEVER have to reset the letters / set screw. Obviously this set up is for an individual / specific weapon so if you move the fake silencer to a different weapon you will most likely have to re-index the outer body again.

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.


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 End Cap with the knurled part extends into the outer tube and is PERMANENTLY ATTACHED to the outer tube thus complying with BATF in regards to NO ACCESS to the inner cavity / air gap. This end cap is CNC machined from billet 7170 T-6 aircraft aluminum to assure lightweight and durability.

The Inner Sleeve / Barrel Extension is made from Weapons Grade Steel to provide the longest life possible for live fire. Additionally the inner sleeve (which the bullet flies through un-obstructed) is sandwiched between the outer body exit hole and the knurled section. This allows the OUTER BODY to ROTATE 360 DEGREES around the inner barrel extension which, give you the ability to get the lettering in the correct position. Being sandwiched between two PERMANENTLY ATTACHED components keeps with the SPIRIT as well as the LETTER of the law.

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.
