Mounting options
These carbon outer barrel extensions are designed to be used directly on our 24 mm threaded outer barrels: SRS G-Spec barrels (A1 and A2) and SRS Sport barrels (16" and 20").
To use these extensions on other barrels, you must use a DT muzzle brake (please check references SBA-FHD-06 and SBA-FHD-07) and a timing shim set (please check reference SBA-SIL-06). To correctly time the muzzle brake, please refer to the YouTube video (link).
You may skip the timing procedure if (and only if) you fully thread the muzzle brake onto the outer barrel thread, ending in an unrealistic position.
Inner barrel length
Please refer to the chart to determine the maximum inner barrel length for your specific setup. For concentricity reasons, we also suggest respecting a minimum inner barrel length (100 mm shorter than the maximum length). Your carbon outer barrel extension is supplied with barrel spacer(s). Install one barrel spacer at the front end of the inner barrel and, if necessary, distribute the others along the protruding inner barrel. Additional barrel spacers can be purchased separately (please check reference SBA-BBS-11).
Offset between muzzle and handguard
Please refer to the chart to determine the distance between the muzzle of the carbon outer barrel extension and the front of the handguard. If the distance is negative, it means that the muzzle of the carbon outer barrel extension will be inside the handguard.
Use as an integral suppressor
It is possible to use your carbon outer barrel extension as an integrally suppressed barrel by using up to 100 mm (recommended) of foam filling on the muzzle side of your carbon outer barrel extension. Please check reference SBA-SIL-18 for additional information.
Warnings
Filling the carbon outer barrel extension with foam may not be legal in your country: users must comply with the laws regarding the use and ownership of sound suppressor devices. Using an inner barrel shorter than the suggested length may cause concentricity issues at the muzzle. Carbon fiber tubes are prone to scratching easily or even breaking from impacts. This product requires additional care from the user, especially
