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

Bought this ARCA adapter for my Savage Precision Elite 338 Lapua. It adapted my Atlas bipod to my rifle seamlessly. Slides up and down the rail to accommodate different shooting surfaces slicker than pig snot. Buy it, you will not be disappointed

Arcade adapter

Previously purchased item and comparing to another similar make, this made more sense as far as build and material. Price point is what made the difference between buy and no buy.

Extremely well made

This little attachment is a must if you have a Arca Swiss rail and want to use your picatinny bipod (or any other pic device.) I fits smoothly and snugs down so it won't move unless you want it to. I used mine to attach my Accu-Tac bipod and I slide the adaptor back and forth to find the optimum location. Works just like they said it would. Quick shipping also.

Arca/ Harris clamp.

First of all the ordering was easy.
Then the product shipped same day.
Arrived two days later in perfect condition.
I didn’t mind it not having instructions to put on the Harris bipod, but others might need that.
Thank you for an awesome product at a great price!!

I purchased to arca adapters from Wiser and am extremely happy with the ver quick service! And the adapters sure beat the picatinney setups that I had. Convinced me to set up all my rifles with them
