Our Reximex Magazine Models... The Big Air Reximex Magazine - Our Big Air Reximex mag was developed using the compact and accurate Reximex Throne 2 22-cal rifle. The Big Air Reximex mag works in the Throne 2 rifle and is much smoother operation than the OEM mags. No bent skirts and the pellets load & feed smoothly! The Big Air Reximex mag easily loads in the breech from the right side. Other calibers available upon request.
