The RSTA OTB (Over the Barrel) Silencer is suited to the shooter who wants the least amount of gas blowback in semi auto systems and the best sound suppression with minimal addition to weapon system length. Our over the barrel mounts are rock solid and provide minimal and repeatable point of impact shift.

Additionally this mounting system reduces fouling due to its low back pressure design and tends to negate the need for tuning gas systems in semi auto systems for reliable operation. The RSTA also features our Patented baffle technology which offers unparallelled reduction of sound both at the muzzle and at the ejection port in semi auto firearms for balanced, and optimized system performance.

The RSTA is CNC machined, and Tig fusion welded for maximum thermal transfer and unparalleled strength and durability. The RSTA is manufactured from high strength, high temperature, corrosion resistant 17-4ph stainless steel. The RSTA suppressor features our flawless bore technology for maximum accuracy and fully blueprinted tolerances.

    Got this for 2 bolt guns in 30-06 and 7mm-08. Both have 24" barrels and being an OTB can it only adds about 5". Sound reduction is great while still being sub 1moa out to 300 yards. The pigs have no idea which way to run. Sorry to see it is in the discontinued item category.

    Absolutely the best suppressor I've ever owned. I wish more they would produce more OTB suppressors.

    Installed on a Bergara B-14 Hunter in .300 win mag. The rifle bullets are practically touching each other at 100yds. The rifle is no louder than my .22 long rifle! I’m very pleased with the performance! And the best part is it will fit multiple calib
