The Picatinny rails that we offer require two attachment points to be able to mount the rail to your rifle.
For synthetic or wooden stocks, we suggest asking a gunsmith to drill a second hole into the stock for installation of a 1913 style Picatinny Rail. Check out our Atlas Bipod Comparison Chart for each of our models and their specifications.
We strongly recommend a competent gunsmith to do all modifications to any firearm. If you have the necessary skillset and tools, check out our video of How to Install a Rail.
