Product Description


Description: AAC Ti-Rant 45M .45ACP Suppressor, .578"-28 Threads. The best selling silencer for .45 Auto, .40 S&W, and 9mm hosts is now even more versatile. The Ti-RANT 45M (Modular) includes all the high quality features users have come to expect from AAC - with a twist. Without the use of tools, and in a matter of seconds, users can reconfigure the Ti-RANT 45M from a full sized 9.0” long silencer (13 oz) into a 7.0” compact model (11.3 oz). One stamp. Two silencer configurations. The main tube is constructed from Grade 9 Titanium for durability and light weight; while the front module tube is made from 7075-T6 Aluminum for weight savings. The encapsulated front module incorporates a design feature that prevents it from inadvertently unscrewing from the main tube during use. The Ti-RANT 45M can be easily hand-disassembled without special tools to allow the entire baffle stack to be removed for cleaning and maintenance.

Not content to just offer a modular version of the predecessor Ti-RANT 45, the Ti-RANT 45M was optimized for even better sound reduction. In the full-size configuration, the Ti-RANT 45M turns in an impressive 33dB reduction dry (132dB SPL) and 41dB reduction wet (124dB SPL), while the compact configuration meters 21dB reduction dry (144dB SPL) and 28dB reduction wet (137dB SPL). Despite being optimized for use on .45 Auto hosts, the Ti-RANT 45M provides excellent sound reduction on 9mm and .40 S&W hosts by using the same ASAP conversion pistons found on the legacy Ti-RANT 45 silencers. Also a 5/8x24 adaptor for use with 300AAC BLK (Subsonic ONLY) is now available making the Ti-RANT 45M an ideal multi-caliber pistol silencer.

Rules & Regulations


NFA Information

-Class III items include (but are not limited to): machine guns (MG), silencers (SS), destructive devices (DD), all other weapons (AOW), short-barreled rifles (SBR) and short-barrel shotguns (SBS).

  • SBR: A rifle having a barrel length LESS than 16" and/or an overall length less than 26".
  • SBS: A shotgun having a barrel length LESS than 18" and/or an overall length less than 26".
  • Silencer: Silencer, Suppressor, CAN, Firearm Muffler are all legally the same thing. A Silencer is a device which decreases the sound of the expelled round by more than 3 decibels. NOTHING silences a firearm - Some CANS make firearms sound quieter than others. Very few CANS make a firearm "Hollywood Quiet" - Some do.
  • AOW Usually refers to a firearm that is manufactured to be disguised as something else:
    • Fountain Pen Guns or Walking Cane Guns are classified as AOW's.
    • A pistol having a vertical foregrip attached is classified as an AOW.
    • A smooth bore firearm (Shotguns have stocks), with a barrel less than 18", and came from the factory with only a pistol grip and has NEVER had a stock attached to it, is classified as an AOW Firearm.
    • The NFA transfer tax for an AOW is only $5 not the "normal" $200 tax stamp cost.

-Anyone who is a legal U.S. resident, 21 years of age and older, a non-felon, and lives in one of the states that allow private ownership of a Class III item. Class III items are illegal in the following states: CA, HI, IL, NY, RI & Washington D.C..

-A silenced firearm is eminently more enjoyable to shoot than one without a suppressor. Suppressors generally increase the accuracy of a host firearm while reducing recoil and eliminating up to 90% of the muzzle signature. Shooters are able to concentrate more on breath control and trigger pull when they are not subjected to the fatigue and distraction of a deafening, bright, muzzle report. Beginning shooters are typically not intimidated when introduced to the shooting sports with a suppressed firearm, and are able to easily hear instructions given to them by trainers as the report of a host firearm is reduced to below the OSHA guideline level for hearing damage. Suppressed firearms are also less likely to disturb any people, livestock, or wildlife that may be in close proximity to where you shoot.

-No, you do not need a license to purchase a Class III items but you do have to pay a one-time $200 tax for each Class III item you purchase. You also have to live in a state where Class III items are legal and have to meet certain criteria to be eligible to own one.

-Determine whether or not your state allows you to own a Class III item. Class III items are legal but they are regulated on a per-state basis. However, the National Firearms Act (NFA) branch of the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) ultimately controls any transfers, and all Class III items are registered by this branch. Individuals, corporations, and trusts can legally purchase and possess Class III items in 45 states. However, if you are a dealer, manufacturer, peace officer, or a law enforcement agency or other government agency, there are additional states where you can own a Class III item.

1. Choosing a product.
2. Locate a class III dealer in your state.
3. After the monetary transaction takes place it will be assigned to you and separated from the rest of the inventory, ensuring that you have a product serial number for your form.
4. Once you have an assigned product serial number, the class III dealer will then give you the ATF Form 4 (5320.4), Application for Tax Paid Transfer and Registration of Firearm, in duplicate with the serial number of the product filled out in the appropriate section. You must fill out the rest of the form in duplicate. You can download the form 4 HERE.
5. You will send in a $200 check or money order with the completed application, along with a recent photo and fingerprint cards. 

1. Obtain the ATF Form 4 (5320.4) (Application for Tax Paid Transfer and Registration of Firearm) from your dealer in duplicate. Some inform's name and address, the model of the Class III item you are purchasing, the overall length of the Class III item, the caliber or gauge of the Class III item, the serial number of the Class III item, and the manufacturer's information. Make sure the dealer signs the appropriate fields. Remember to complete all information in duplicate.
2. Fill out the required information on the front of the form, including your name and address. Complete the back by answering the questions and stating the reason you are acquiring the Class III item. Sign and date the back of the form. Again, remember to complete all information in duplicate.
3. Affix a recent color passport-sized photograph of yourself on the back of each copy of the form.
4. Acquire a signature of the chief law enforcement officer of your county or your local sheriff. Don't let this step scare you; this is a routine request. If you feel that your police chief or sheriff will not sign the Form 4 because of personal or political concerns with the Second Amendment, do not worry. You can bypass them by purchasing the silencer under your Limited Liability Company (LLC) or corporation, or under a trust.
5. While you are at the station obtaining the required signature, ink up your fingers and get two copies of FBI fingerprint cards (FBI Form FD-258) that you will send in with the two duplicates of Form 4.
6. Place both completed copies of Form 4, the two copies of FBI fingerprint cards, and the completed Certification of Compliance form in an envelope, along with a check or money order (payable to Bureau of Alcohol, Tobacco, Firearms, and Explosives) for $200 and mail to the address listed on Form 4. We advise that you use a check and not a money order so you can see when the ATF cashes your check. This is a great way to confirm if the form actually arrived and is being processed. Otherwise, you may just be waiting for two to six months for approval, when, in fact, your paperwork never arrived.
8. After the ATF approves Form 4, they will put a stamp on one of the two copies you sent them and then send it to the dealer where you purchased the Class III item. The dealer will then notify you that the paperwork has returned and that the Class III item is ready to pick up.
