steel bristles so residue left on the Stainless mount geometry by thebrush may give the appearance of light rust- Application of CLP tothe mounting bore between uses will prevent that. The carbon steel

bristles have higher strength helpful in removal of hard, baked on,copper fouling. Make sure you clean the front flash hider supportforward of the threads, as this is a second bearing surface for themounting system.

Finish: High rate of fire operation at temperatures exceeding 1100Fafter firing more than 110 rounds in 1-3 minutes, may damage thefinish which is Norrell Moly coating and has a minimum thermal

breakaway of 1000F. If refinishing is desired, rub the old loosened,heat affected paint off with rubbing alcohol and a clean rag and applythe finish of your choice. We recommend Norrell Moly. Use a lightcoat silencer standing on the rear cap. Painting the mount bore, orthreads will result in tolerance interference, rendering the unitinoperable till interfering coating thickness is removed.

CAUTION: The RSTA Silencer combats the Impulse noise at themuzzle of your weapon and cannot account for the actions associatedoperating noise which will vary by weapon type, system wear, and

barrel length. For the highest level of hearing protection, wearhearing protection at all times while using your silencer.

MILITARY USE: In operational environments where concealmentis paramount, first round flash can be mitigated by firing the weaponwith the suppressor mounted, prior to an operation, and immediatelytaping the muzzle aperture of the suppressor to trap combustion gases(an oxygen free environment). Additionally the optional very lightcoat of oil from the maintenance section will reduce first round flash

as well. Some field testing should be conducted, ideally, to derive theparticular strategy that works best for your unit.

Infrared heat signature can be mitigated by using a suppressor coversuch as the SUPCOV. For optimal concealment less than 30 roundsshould be fired. Covers insulate, so they add thermal stress to thesuppressor, reducing cooling. Reduced cooling reduces tolerablemaximum ROF, so covers are not recommended unless needed toreduce thermal signature or mirage (with scoped rifles) or to mitigaterisk of burns during transition drills.

weapon and confirm alignment on each new weapon prior to the firstuse of your RSTA suppressor with un-tested weapons. This willsafeguard your suppressor from damage caused by poorly machined

barrel threads. If alignment does not appear to be right, or if youdesire the most minimal POI shift and maximum safety from bafflestrikes or other issues, send your barrel to ADCO firearms in Ohio for

barrel threading. www.adcofirearms.com

Recommended rate of fire considerations: The RSTA isconstructed of TIG welded high strength, high temperature corrosionresistant, aerospace alloys. Your RSTA is extremely durable;however care should be taken to prolong service life. Therecommended maximum rate of fire is no more than 60 rounds on fullauto [7.62x51mm], followed by 14 rounds per minute sustained.

Do not quench/cool your heated silencer with water, ice, or snow.Quenching metals will em-brittle them, can warp parts, and may damage or destroy your silencer. Allow your silencer to air cool.

Calibers and Ratings: The RSTA 7.62mm sound suppressor, used inconjunction with 5/8x24 threaded mounts, is rated for:.300 Winchester Magnum ammunition in barrels 24 OAL or longer7.62x51mm, and 6.5x47mm Lapua ammunition in barrel lengthsdown to 14.5300 Whisper (or Remington equivalent) in barrels as short as 9.55.56x45mm ammunition and all lesser calibers in barrels down to10.5 (over the barrel mounting and gas block positioning will

probably reduce RSTA possibilities to 12.5).

Maintenance: Clean your suppressors mounting system and muzzledevice after every use to ensure mating surfaces are free of copperand carbon fouling. Failure to clean the mounting system can resultin your RSTA becoming stuck to the muzzle device on your weapon.

No other maintenance is required with this silencer. If the silencer forwhatever reason becomes filled with water, shake out excess water inthe direction of the rear mount and store unit muzzle up to dry. Astandard nylon bristle, all purpose brush should be sufficient forcleaning rear mount threads, while an Oatey No. 31328, 3/4 inchHeavy-Duty Inside Diameter Fitting Brush can be used to clean themount surfaces further inside the suppressor. This brush is availablefor $2.20 currently at Home Depot in the plumbing department, andcan be purchased online from other retailers. The brush has carbon

Thankyou for purchasing a RSTA sound suppressor. We appreciateyour business. Please read these instructions carefully prior touse.

Compatibility: The RSTA suppressor requires a RSTA flashsuppressor or muzzle brake mount of the appropriate caliber andthread pitch. 5.56mm mounts are threaded 1/2x28, and 7.62mmmounts are threaded 5/8x24. Both thread patterns require a typicalthread length of .630. Barrels must be no greater than .775 OD aminimum length of 2.55 rear of the forward most surface of the

barrels muzzle, for compatibility with mounts.

Muzzle Brake / Flash suppressor mounting: See the included, butseparate, RSTA Muzzle Brake Flash Suppressor manual for brakeor flash suppressor mounting procedures to ensure optimalcompatibility with the RSTA suppressor. Proper muzzle accessorymounting procedures are required to ensure safe use of your

suppressor.

To mount your RSTA silencer: Carefully place the suppressor overthe RSTA muzzle accessory. The silencer will bottom out when thethreads on the suppressors rear mount touch the threads on the RSTAmuzzle accessory. When this occurs, engage the thread by rotatingcounter clockwise until you feel the starting point of the thread. Nexttighten the silencer by rotating it clockwise 4-6 rotations until thesilencers tapered collar engages the front support. Tighten thesuppressor firmly.

Confirm alignment! Following the instructions in the included butseparate, RSTA Muzzle Brake Flash Suppressor manual, clear your
