JJFU Aero Sonic™ LSFS
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.
Inconel 625 is used in the first baffle because of its high strength properties and resistance to elevated temperatures.
The remaining four baffles are made of Titanium, known for its lighter weight while still maintaining the strength needed for the amount of heat and pressure that is built up in the JJFU Aero Sonic™ LSFS.
By controlling the air pressure passing through the suppressor in a gentle manner, heat is drastically reduced. This is made possible by not hyper charging the suppressor chambers with air. Packing hot air on top of hot air unregulated creates a lot of heat. This is why most suppressors cannot be touched after one 30 round magazine. The Aero Sonic patented design slows down muzzle pressure by controlling the blast of air as it enters the suppressor chamber. With the muzzle pressure reaching 1500 psi you cannot simply deflect it with hopes of making it quieter. The air pressure must be controlled, and bled off, slowing it down.
Our unique design lets the air expand in the pulse shape of a super sonic sound wave. All internal surfaces are machined with organic curves in an effort to reduce turbulence. Turbulence = Harmonics = Sound. The more gently you can slow down the air, the quieter the results.
Super Sonic air pressure is also regulated with our patented inner barrel design. Pressure relief slots are machined in an oscillating pattern. This regulates the outward flowing air to the suppressor chambers. This helps the already expelled air to bleed off, and not be hyper charged as it passes thorough the suppressor chambers.
Nighttime testing was conducted with 5.56 rounds shot in semi auto and full auto. Zero muzzle flash was produced from 25 yards in front of the shooter.
The JJFU Aero Sonic™ LSFS is fully serviceable and comes with the tools needed to disassemble it and clean as needed. Our original models have 15,000+ rounds through them and are still going strong without loss of performance.
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.
