Capitol Armory Meters The JJFU Aero Sonic Silencer

    Before we get into Capitol Armory’s impromptu testing of the Aero Sonic 5.56 rifle suppressor, let’s take a quick look at the above new Jesse James Firearms Unlimited (JJFU) take-down model. Named the ‘La Bomba’, JJFU quietly (see what I did there) debuted the new silencer a few days ago on their Facebook page.

    The JJFU product page has been updated with a little initial information on the ‘La Bomba’:

    La Bomba – $1299

    The JJFU La Bomba suppressor is a 3 piece Hiram Maxim based suppressor. It can be unscrewed and cleaned as needed, prolonging the life of your suppressor.

    Extrapolating from the limited information we have, the ‘La Bomba’ appears to be a .30 caliber suppressor capable of handling the pressure of a .30-30 round fired from a ~10″ barreled Winchester Model 94. We will update the post with additional information on the new JJFU silencer as it comes in.

    Moving on to capitol armory…

    Whether you love him or hate him, Jesse James and his firearms company are here to stay. And while I have been critical of his silencers in the past, I can certainly appreciate his pro-Second Amendment stance and his love for firearms in general. And there’s no denying his artistic vision. My previous gripes have centered around the lack of test data and the price point. Sure, the styling might not be my cup of tea, but I’m not the one with the hit TV show and the millions in the bank.

    Anyway, when I first caught wind of Capitol Armory’s social media posting surrounding the testing of a JJFU Aero Sonic silencer, I was intrigued and had to know more. In previous years, independent testing efforts of the Aero Sonic silencer did not to come to fruition.

    The Capitol Armory team was enjoying a day at the range when a fellow shooter showed up with an JJFU AR-15 and Aero Sonic suppressor. Being the prepared silencer Boy Scouts that they are, the CA shooters whipped out a decibel meter and asked the fellow range-goer for the chance to test the unique can.

    To say the results were surprising would be disingenuous: aside from numbers previously reported by the JJFU team, there was no baseline to make a solid comparison. In addition to the dB meter, the Capitol Armory guys shot the SilencerCo Specwar 5.56 as a basic control-set for the conditions of the day.

    Specifications from the JJFU Aero Sonic product page:

    JJFU Aero Sonic™ LSFS – $2995

    We are offering a revolutionary new low signature firing system(LSFS), the Jesse James Firearms Unlimited (JJFU) Aero Sonic™ LSFS. Current testing has audio peaks of 116db at the muzzle, with no muzzle flash using 5.56 Green Tip ammunition fired from an M4 with a 10-inch barrel. While almost all suppressors on the market use the Hiram-Maxim theory of stacking baffles and shooting through them in the hopes of dampening sound, the JJFU Aero Sonic™ LSFS has reengineered sound and flash suppression starting from the ground up. Jesse James and West Coast Choppers has over 25 years of experience in making motorcycle mufflers. The theory behind that is to keep the pressure in, while keeping loud sound signature.

    We have found that our approach to the field of sound and flash suppression is unprecedented, as shown by our recent patent approval for our design which shows no cited references in the last 100 years.

    The JJFU Aero Sonic™ LSFS works in the opposite by letting the pressure out, while keeping the sound and flash signature to a minimum. The JJFU Aero Sonic™ LSFS is made of the highest quality, lightest materials available without compromising strength or reliability.

    The clamshell is made of 7075-T6 aluminum billet, has an ultimate tensile strength of 74,000–78,000 psi (510–572 MPa) and yield strength of at least 63,000–69,000 psi (434–503 MPa). It has a failure elongation of 5–11%. The barrel extension is made of stainless steel.

    Ok, so the Aero Sonic may not be my style or in my price range, but those numbers are certainly respectable for a modern 5.56 silencer. And being that Jesse himself as well as JJFU are supportive of the gun community and NFA ownership, I can’t find a reason to criticize the man for doing something he loves while providing a unique product to the consumer market.
