your Recce 7 suppressor, that is an indicator that you are approaching
the threshold of abusive use. Abusive use increases the likely-hood of suppressor damage. If refinishing is desired, rub the old loosened,
heat affected finish off with rubbing alcohol and a clean rag and apply
the finish of your choice. We recommend Norrell Moly. Use a light
coat with the suppressor standing on the rear cap. Painting the mount, mount bore, or threads may result in tolerance interference or poor
alignment, which is a potential source of suppressor damage. Do not
paint the mating surfaces.
CAUTION: The Recce 7 Suppressor combats the Impulse noise at
the muzzle of your weapon and cannot account for the action’s associated operating noise, which will vary by weapon type, system
wear, and barrel length. For the highest level of hearing protection,
wear hearing protection at all times while using your suppressor.
MILITARY USE: In operational environments where concealment
is paramount, first round flash can be mitigated by firing the weapon
with the suppressor mounted, prior to an operation, and immediately taping the muzzle aperture of the suppressor to trap combustion gases
(an oxygen free environment). Additionally the optional very light
coat of oil from the maintenance section will reduce first round flash as well. Some field testing should be conducted, ideally, to derive the
particular strategy that works best for your unit.
Infrared heat signature can be mitigated by using a suppressor cover such as the SUPCOV. For optimal concealment less than 30 rounds
should be fired. Covers insulate, so they add thermal stress to the
suppressor, reducing cooling. Reduced cooling reduces tolerable maximum ROF, so covers are not recommended unless needed to
reduce thermal signature or mirage (with scoped rifles) or to mitigate
risk of burns during transition drills.

Recommended rate of fire considerations: The Recce 7 is
constructed of TIG welded, heat treated, high strength stainless steel, which is substantially stronger than typical stainless steel, for high
pressure conditions. Your Recce 7 suppressor is extremely strong and
durable, however care should be taken to prolong service life. The
recommended maximum rate of fire for self-loading calibers is no more than 60 rounds on full auto, followed by 14 rounds per minute
sustained.
Do not quench/cool your heated suppressor with water, ice, or
snow. Quenching metals will em-brittle them, can warp parts,
and may damage or destroy your suppressor. Allow your
suppressor to air cool.
Calibers and Minimum Length Barrel Ratings: The Recce 7
7.62mm suppressor is rated for 7.62mm ammunition in barrel lengths
as short as 14.5”. Use of longer barrels will promote maximum
suppressor wear life.
Maintenance: Clean and protect your suppressors mounting system
and your MBS-A mount after every use. Ensure mating surfaces are
free of corrosion, as well as copper and carbon fouling. Failure to
clean the mounting system or remove your suppressor for storage after use can cause your suppressor to become stuck to the muzzle
device on your weapon. Rod the bore with a brass 9mm bore brush
coated with your favorite cleaner / lubricant / corrosion inhibitor. Spray a light coat of WD-40 or Rem Oil into the suppressor body for
storage to displace moisture and further reduce the minimal risk of
corrosion. Give the suppressor body and threads a light coat of oil, and wipe dry. In operational environments, the suppressor can be re-
mounted after cleaning to protect threads from damage, or the MBS-
A thread protector can be used for that purpose.
If for some reason an excessive amount of oil is used in maintenance,
drain the excess prior to firing. Fluids are incompressible- a
substantial amount of fluid will raise operating pressures with potentially dangerous results. Do not use grease or water in your
suppressor.
Finish: High rate of fire operation at temperatures exceeding 1100F
after firing more than 100 rounds in 1-3 minutes, may damage the
finish. The finish is Norrell Moly coating and has a minimum thermal breakaway of 1000F. If you witness the finish baking off of
Thankyou for purchasing a Recce 7 sound suppressor. Please read
these instructions carefully prior to use.
Compatibility: The Recce 7 suppressor is adaptable to 7.62mm
weapons through the use of an appropriate muzzle brake, suppressor
attachable (MBS-A) mount.
CAUTION: Your suppressor can be interfaced with .338LM MBS-A
mounts, but does not have sufficient bore clearance for safety with these rounds. Firing larger than .308” diameter bullets through your
7.62mm Recce 7 suppressor may damage or destroy your suppressor
and could cause death or serious bodily harm to people in the vicinity of your rifle.
Safety Considerations! Unload your weapon in accordance with its
manufacturer’s user manual prior to mounting the sound suppressor. Remove the bolt or bolt carrier group from the weapon prior to
inspection of the mounting alignment.
To mount your Recce 7: Grasp the suppressor and carefully place it
over the host weapons installed MBS-A mount. The suppressor will
bottom out when the threads on the MBS-A touch the threads on the suppressor. When this occurs, engage the thread by rotating counter
clockwise until you feel the starting point of the thread. Next tighten
the suppressor by rotating it clockwise until it is fully tightened.
Tighten the suppressor firmly, but do not over-tighten, as this can make the suppressor difficult to remove after use.
Confirm alignment! Visually confirm alignment on every untested weapon prior to first use. The practical method involves placing
white paper in the breach, and looking through the suppressor bore,
parallel to the walls of the barrel bore on all sides, comparing
clearance to elements of the suppressor bore. If alignment does not appear to be right, or if you desire the most minimal POI shift and
maximum safety from baffle strikes or other issues, send your barrel
to ADCO firearms in Ohio for barrel threading. www.adcofirearms.com
Warning! Risk of Burns: Suppressors get very hot during use temperatures of 450-900F are typical of normal use. Use of a
suppressor cover can mitigate risk of burns: see military use
considerations for more information on suppressor covers.
