Description
These Carbon barrel extensions are designed to be used directly on our 24mm threaded outer barrels: SRS G-Spec barrels (A1 & A2) and SRS Sport barrels (16’’ & 20’’).
To use these extensions on any other barrels, you will have to use a DT muzzle brake (please check references SBA-FHD-06 & SBA-FHD-07), and a set of timing shims (please check reference SBA-SIL-06). To properly time the muzzle brake, please refer the Youtube video (https://www.youtube.com/watch?v=829ujuwRL6Q&t)
You can skip the timing procedure if (and only if) you screw the muzzle brake all the way onto the outer barrel thread, ending in an unrealistic position.
Warnings
Filling the carbon barrel extension with foam may not be legal in your country: users should obey to the law regarding usage and ownership of sound suppressor devices. Using an inner barrel shorter than suggested length may generate concentricity issues at the muzzle. Carbon fiber tubes are prone to get scratched easily, or even broken by impacts. This product requires extra care from the user, specifically for the longer versions. Due to the manufacturing process, all tubes present an overlap pattern, and may not be exempt of small visual defects.
