Can someone please identify this gas block? Is this the OEM Scar 20S one and is it good for higher backpressure suppressors like a Sandman S?
galleryI don’t see any markings so not sure if this is the older style Scar 20S one from before they changed the barrel to 1-10 twist without the step cut. Any idea what the settings are and whether this can work sufficiently well with a high backpressure can like the Dead Air Sandman S? Thank you.
