User Manual
To maximize efciency and reliability when using our silencer, it is
imperative users ONLY employ FACTORY LOADED ammunition.
DO NOT fire frangible or pre-fragmented ammunition through
any Advanced Armament Corp. silencer. Evidence of use of any
frangible or pre-fragmented ammunition will void the warranty,
and any repairs made necessary from the use of frangible or pre-
fragmented ammunition will be invoiced to the owner.
GUIDELINES FOR RIMFIRE SILENCERS
For maximum noise reduction, it is necessary to use ammunition which
will remain subsonic in YOUR host rearm. Most ammunition, with the
exception of hyper velocity loadings. will remain subsonic when red
from a pistol length barrel. Rie length barrels, due to their higher
velocities, often require standard velocity or subsonic offerings to deliver
the most quiet sound signature. European ammunition manufacturers
such as Eley and RWS produce subsonic .22LR ammunition specically
for use in silencer equipped ries. Two domestic .22LR loads known for
quality and consistency are CCI Green Tag and Federal .22LR Olympic
Match. They typically deliver match grade accuracy and a very pleasing
sound when used with a silencer. Other more economical choices are
standard velocity and subsonic offerings from Remington or CCI. They
will remain subsonic in both ries and pistols over a broad variety of
environmental conditions, and produce the quietest sound signature
when red through a silencer.
We do caution against the use of 60 grain Sniper Subsonic
(SSS) ammunition from Aguila, as it has a tendency to de-
stabilize in .22LR barrels with a standard twist rate of 1 in 16.
A de-stabilized projectile can yaw while traversing the length
of the silencer and damage its internal components. Users
that are interested in this heavy loading should contact the
manufacturer and/or importer of Aguila ammunition for their
recommendations on proper barrel twist rates to stabilize the 60
grain SSS projectile.
