The FLY 9 and the FLY 45 share many common design traits but have some differences.
This manual is for the FLY 9. The FLY 45 manual is overe here.

GENERAL SAFETY RULES

  1. Do not assemble or disassemble the suppressor while attached to a firearm.
  2. Do not install or remove the suppressor from a firearm while the firearm is loaded.
  3. This is not a comprehensive list of safety rules. Always follow the standard gun safety rules, such as the "NRA Gun Safety Rules" while handling firearms.

PARTS DIAGRAM


SHORT/LONG CONFIGURATION ASSEMBLY/DISASSEMBLY

The FLY can be shot in "SHORT" and "LONG" configurations by omitting or including the MODULE respectively.

To convert from LONG to SHORT: Remove EXIT END from MODULE using a quarter or back of a house key. Next, unscrew MODULE from SUPPRESSOR BODY. Install and tighten EXIT END back onto the end of the SUPPRESSOR BODY. These parts should be "hand tight."

To convert from SHORT to LONG: Remove EXIT END from SUPPRESSOR BODY. Screw the MODULE onto the end of the SUPPRESSOR BODY. Replace EXIT END onto the end of the MODULE (you can use a quarter or back of a house key). These parts should be "hand tight."

REAR CAP AND BOOSTER ASSEMBLY/DISASSEMBLY

The FLY 9 ships with both a BOOSTER SPRING and FIXED BARREL SPACER. The BOOSTER SPRING is for use with pistols that use a Browning-style action or otherwise require linear decoupling (ie, most pistols). The FIXED BARREL SPACER is for use with firearms that have a fixed barrel (ie, most PCCs or subguns). The BOOSTER SPRING should NOT BE USED on fixed-barrel subguns, PCCs, or rifles.

Tool fitment for REAR CAP: The three-pointed handling interface on the back of the REAR CAP will fit a socket. Specifically, a 6-point 1 1/8" (inch and an eighth) socket will fit the end of the REAR CAP. This may be used if you need to apply more torque than you can by hand on the small handling surfaces of the REAR CAP. Do not over-torque this part; you should not need to use more torque than you can apply by hand holding onto the socket.

To swap between the BOOSTER SPRING and FIXED BARREL SPACER, remove the BOOSTER ASSEMBLY by unscrewing the REAR CAP from the back of the SUPPRESSOR BODY. Install either the BOOSTER SPRING or FIXED BARREL SPACER over the PISTON and reinstall the assembly into the rear of the SUPPRESSOR BODY. Do not over-tighten the REAR CAP. If you are holding the 1 1/8" socket in your hand (no wrench), you should tighten these two parts hand tight.

Note that the REAR CAP will not not screw all the way into the SUPPRESSOR BODY when using the FIXED BARREL SPACER. In this configuration, the REAR CAP will bottom out by hitting the FIXED BARREL SPACER.

O-RING LOCATIONS AND MAINTENANCE

There are 3 O-rings in FLY 9.

  • One behind the male threads on the EXIT END.
  • One behind the male threads on the MODULE.
  • One on the inside of the REAR CAP where it contacts the shaft of the PISTON.

There is NO O-RING between the REAR CAP and the BASE SUPPRESSOR.

O-RINGS should be checked regularly and replaced if damaged. O-RINGS are available from TBAC or you can use the following part numbers from MCMASTER-CARR: 9464K72 for the REAR CAP; 9464K79 for the MODULE and EXIT END.

USING OTHER ADAPTERS AND PISTONS

The rear of the suppressor body is threaded 1.125" x 28tpi, so it can use Silencerco or KVP (Kaw Valley Precision) -- or other compatible -- adapters for Tri-lug, direct thread, etc. Note that "self-contained" tri-lug adapters are recommended for compatibility.

The FLY 9 ships with a 1/2-28 piston and a fixed barrel spacer (spring replacement). It is compatible with the Rugged/Griffin/SilencerCo/TBAC standard pistons. You should use the TBAC FLY9 wave-style BOOSTER SPRING even if you use a different piston (eg, for M13.5x1 LH)

We do not guarantee the function of third-party pistons or rear adapters (ie, adapters that replace the REAR CAP and BOOSTER ASSEMBLY). Be sure the combination you are going to use will not cause problems or baffle strikes. Use of third party adapters and pistons does not invalidate our warranty; however, damage caused by using third party adapters or pistons will not be covered under warranty (it may be fixed at "shop rate."

INSTALLATION/REMOVAL FROM FIREARM

DO NOT INSTALL OR REMOVE FROM A LOADED FIREARM

Make sure the EXIT END, MODULE (if present), and REAR CAP, are all tight and that the PISTON and BOOSTER SPRING or FIXED BARREL SPACER are assembled correctly.

For pistols and PCCs, screw the suppressor onto the muzzle threads. Note that 1/2-28 threads on 9mm usually shoulder on a proper barrel shoulder. Other threads such as M13.5x1 LH often shoulder the muzzle on an internal shoulder on the booster.

Periodically make sure the suppressor is still tight on the host. Beware that after shooting the suppressor may get hot.

NOTES ON HOST COMPATIBILITY - SEMI-AUTO PISTOLS

Pistols that use a Browning style recoil system or otherwise need a linear decoupler will use the BOOSTER SPRING in the assembly. Operation of these pistols depends on a balance between: (1) the pistol's recoil spring, (2) the booster spring, and (3) the ammunition strength. We have designed the FLY 9 to allow "most" modern semi-auto pistols that have standard pistol threads to operate without modifications. Keep in mind that spring compatibility may change from LONG vs SHORT configurations and from ammo type to ammo type.

** NOTE ABOUT PISTON COMPATIBILITY WITH MODERN SIG PISTOLS (P365, P320) **
The industry standard is, or has been, that threaded 9mm pistol barrels use 1/2-28 threads and bottom out ("shoulder") on a shoulder behind the threads. This is true for virtually all pistol barrels and virtually all 9mm 1/2-28 booster pistons are designed to work ths way. We have discovered that factory SIG threaded barrels for the P320 and P365 famliies, and possibly others, are not set up this way. In contrast, they are set up to be indexed on the muzzle, which makes them not compatible with most 1/2-28 9mm pistons on the market.

Our original, or "A" version, 1/2-28 piston is designed to work with muzzle threads that have a thread length of approx 0.40-0.45" and a shoulder behind those threads of at least 0.550".

If your barrel does not look like this, then you need a muzzle-indexed 1/2-28 piston. We will have a "B" version of the 1/2-28 piston available soon. In the meantime, please contact us for a solution.

NOTES FOR USING REGULAR FULL POWER AMMUNITION: If your pistol does not quite return to battery or does not fully eject empty cases, you may need a slightly weaker than stock recoil spring in your pistol.

NOTES FOR USING "EXTRA SUBSONIC" AMMUNITION SUCH AS "HUSH" OR "STELTH": If your pistol exhibits the symptoms listed above for "full power ammunition", does not eject, or does not even unlock, you may need a weaker recoil spring in your pistol.

We have noted the following combinations that are known to work with HUSH/STELTH ammunition:

  1. Glock 17: 13 or 11-pound recoil spring;
  2. Glock 19; 13-pound recoil spring;
  3. Glock 43/43X; 15-pound recoil spring;

BOOSTER SPRING LIFETIME

Our special wave-type BOOSTER SPRING is made to exceed the lifetime of other booster springs on the market by a factor of up to about 20x. Our spring will "break in" in the first 50-100 rounds and should have a lifetime during which it provides the original spring constant for a minimum of 1000 rounds, but typically 2000-2500 rounds. The spring will need to be replaced once its free length is less than 1.25 inches.

CLEANING INSTRUCTIONS

Periodically clean the suppressor to remove accumulated carbon. First, completely disassemble the suppressor. The SUPPRESSOR BODY, MODULE, and END CAP should be cleaned using CLR per our normal cleaning instructions (TBAC GENERAL CLEANING INSTRUCTIONS). The REAR CAP, PISTON, BOOSTER SPRING, and FIXED BARREL SPACER can be cleaned by hand using a toothbrush and standard cleaning solvent. Do not soak any steel parts in CLR. Rinse with water, dry, and reassemble.

The shaft of the PISTON where it goes into the REAR CAP should be kept clean and lubed for best operation.

ARMORER LEVEL INSTRUCTIONS

There are no armorer level operations for this suppressor. Please contact TBAC if you need additional service.
