Area 419 Arcalock Arm Features The Area 419 Arcalock Arm is designed specifically around the Garmin Xero C1 chronograph letting the shooter take full advantage of the unit s compact size and versatility by mounting it either on the bottom or the top of the rifle. The arm supports multiple mounting configurations including in-line mounting via a diving board or side mount or offset mounting using an Arca rail or elongated Picatinny rail. This flexibility lets the shooter position the chronograph exactly where it works best for their setup and barrel profile. Milled from billet aluminum at roughly 1 lb and finished in black the arm is built to the same machining standards Area 419 applies to its scope mounts and bases. The arm s mounting pattern accepts either an Area 419 Arcalock clamp or a QD Picatinny lever clamp giving the shooter a choice between a dedicated Arca interface and a quick-detach Picatinny option. Beyond rifle use the Arcalock Arm can be removed from the gun entirely and attached to any tripod equipped with an Arca head for stationary chronograph use at the bench or on a tripod-mounted rest. Convenient mounting hardware is included so the shooter can get the Arm installed without hunting down additional parts. For shooters running a Garmin Xero C1 chronograph the Area 419 Arcalock Arm is a purpose-built way to keep it mounted and ready on the rifle.
