I managed to snag one of the new non rec. charging handle SCAR 16s. I am gonna send it in right away to chop the barrel but my question is about the jets. I know they supposedly lightened the bolt carrier and changed the gas system. On the old ones everyone pretty much knew what to swap the jets for when you cut it. Now on the new ones- who knows?! I may have to be a test for it and see what it runs with. I have a surefire supp. but that will not be out of jail for awhile! Does anyone have any ideas or tried it yet? I think they are to new to actually have anyone cut one yet.
