Our Umarex Komplete Magazine Models... The Komplete 177-14/22-12 shot Magazines - will generally fit under most any scope rings. Our Big Air Mags will snugly hold the pellets in the cylinder without the hassle of them falling through like on the OEM mags. No bent skirts and the pellets load & feed smoothly!
We designed the Komplete mags with a snug friction fit on the barrel to hold it in place. We oversized the grippers a bit to prevent a loose fit and to account for the tolerance we've seen between different rifle barrels. You'll need to firmly pop the mag into the breech with your palm the first time. This will allow the grippers to conform to the barrel and after a couple insertions the fit will give a nice easy snap in and work great.
