The SRD338TI-QD is a Grade 5 titanium silencer using fast-attach muzzle devices to attach the silencer to the rifle. The rear mount of the silencer has wrench flats to torque the silencer to the muzzle device. There is a secondary retention latch that is depressed to remove the silencer from the mount. The SRD338Ti-QD is rated up to the 338 Lapua Mag and any other rifle catridges that are of equal or less projectile diameter, pressure and case capacity. Examples of this would be .204 Ruger, .223/5.56x45mm, 5.45x39mm, 300 Win Mag, 7.62x39mm, 300 Blackout, 6.5 Grendel, 6.5 Creedmoor, 6.8 SPC, .260 Remington and other cartridges. The SRD338TI-QD comes with one M18x1.5mm Taper-Lok muzzle brake. Accessory muzzle devices and other thread pitches are available. Features: Grade 5 Titanium: Grade 5 Titanium enables increased volume without an increase in weight. Taper-Lok: While compatible with all traditional 90° shouldered barrels, when using Sig Sauer tapered shoulered barrels, this optimizes alignment, improving accuracy and greatly reducing point-of-impact (POI) shift. Wrench Flats: Easy removal, even with heavy carbon build-up. The wrench will automatically disengage the secondary retention latch with no ratchet teeth to wear out.
