The SRS Arca Balance is made with one purpose, to give you the lightest and sleekest option for a rail at the balance point of your rifle. Made from 7075 aluminum. We were able to add weight reducing pockets while retaining strength and rigidity. This rail is designed to wrap around the front action screw and mounts with two bolts in front of the recoil lug. Our 10-32 fasteners come with 10-32 tee nuts for installation (preferred method). 1/4-20 include 1/4-20 tee nuts. 10-24 MLOK include MLOK nuts.

The “Flat” rail has a FLAT bottom, “Radius” has a small groove down the center like most of our other rails.
