High power upgrading exclusively for the Benjamin Marauder platform. At Airgun Revisions we have developed trick machining and tuning methods that stood the test of time. High power and shot to shot consistency without the use of a regulator. Mechanical tuning is what we strive for. What does this mean? No regulator to go bad, leak or go out of adjustment. The gun is always ready to do it’s job each and every time you use it. Less is more approach. Our valve throating can reach diameters of .210 with an Airgun Revisions exclusive transfer port. Toped off with matching valve and Highly tunned SSG hammer setup. The tuning service is $325 and parts are not available for sale due to all the machining required to transform your gun into a total beast. Click on the SERVICE tab on the homepage of Airgun Revision. Print and fill out service form and ship it with your gun. All info is provided on form. Form must be fully filled out. Shot count is dependent on energy level you set at, meaning the gun is power adjustable.
