The Area 419 ARCALOCK Rail for Garmin Xero allows you to mount the unit in-line with the barrel via diving board or side-mount, or offset from the rifle with an ARCA rail or elongated pic rail. The arm can also be removed from the rifle and attached to any tripod with an ARCA head for stationary use. The mounting 17S mounting pattern allows the use of either of the Arcalock clamps or a QD picatinny lever clamp. Milled from billet aluminum, and including convenient hardware, this is the perfect compliment for your Garmin Xero C1 ChronographFeaturesMachined in house from 6061-T6Type III Black Hardcoat Anodized
