View Full Version : Installing HDPS faux suppressor on HK USC

11-29-2011, 11:09 AM
Has anyone had the pleasure of attaching an HDPS faux suppressor to an HK USC? I just purchased one, and do not have the vents in the USC upper yet. Just wondering if anyone can provide insight on the process. I understand you must drill a couple holes to get the suppressor to mount. Thanks for any help, greatly appreciated.
