This is the Ruger BX-25 factory 25 round magazine for the Ruger 10/22.
It has a bunch of nice features including the same 30 degree angle steel feed lips as the Ruger rotary magazines, a constant force stainless spring, anti-tilt self lubricating follower and can be easily stripped for cleaning. Check out our blog post for more info and a video.
We shoot 10/22s ourselves and have found them way more reliable than the high capacity Butler Creek and American Eagle magazine we were using previously. The fact that you can strip these 25 shot banana magazines is great, where as the Butler Creek equivalents are molded closed and there is no way to shift wax and particle buildup.
We’ve also found the black polymer casing to be very durable, after dumping them on concrete range floors.
Will fit any Ruger .22 LR 10/22, 77/22 or SR-22 rifle.
