The Wiser Precision Arca-Adapter Pro is the missing link between your Arca-Swiss (1.5" dovetail) rail equipped precision rifle and your large inventory of accessories.

The Arca-Adapter Pro comes standard as an Arca-Swiss to Picatinny adapter. It's also cut with a 17S (Atlas bipod) pocket to accept various accessories and bipods. It is compatible with all Atlas bipods excluding the 5H. The combination of a Picatinny rail and the 17S pocket allows you to use your inventory of gear on your Arca-Swiss rails.

Aggressive knob geometry provides meaningful grip through gloves or with bare hands when tightening or loosening the plate. The Arca-Adapter Pro Arca-Swiss clamp opens wide enough that it can be attached to an Arca-Swiss rail from the bottom, allowing you to connect your bipod or other device in between stops on an Arca-Swiss rail.

ARCA-Adapter Pro for DT SRS Covert

I discovered Wiser Precision ARCA-Adapter Pro for the DT SRS Covert. For several years I had heard that standard length SRS adapters from other manufacturers were out in the market but that Covert wasn’t supported by anyone.

Recently I checked the Wiser Precision site and found their Covert ARCA-Adapter. I ordered on and it arrived within 2-3 days. It fits perfectly on my SRS-A1 Covert.
Precision machined and fits my tripod Ball Mount perfectly.
Sturdy finish and reasonably priced.

I’m going back to Wiser Precision to order their hiking sticks adapter to use for shooting sticks when I don’t want to carry a tripod. Should work really well for wolf calling in the mountains.

Great Products and fast Service. I can’t ask for more from a company.

Great quality, excellent functionality.

Product is stable, easily adjustable, full metal and high quality construction. I have it attached to my atlas and shoot .5 MOA groups with it!

quality product

The ARCA Adapter Pro is a great product. It fits well and moves up and down the full-length ARCA rail smoothly. More importantly, this product exemplifies the high quality, fit, function and durability that comes from true American Manufacturing. The finish is flawless and the product has exceeded my expectations.
