This is the Swemag FT-25 25 .22LR magazine for the Ruger 10/22.
We've been looking long and hard for a decent Ruger 10/22 magazine which will work nicely with the McFadden Lightnin Grip Loader and we have found one.
The neat Swedish all polymer design makes it both durable, weather resistant and good value. The casing is harder wearing than the BX-25 and has better sealing.
The Swemag matches many of the Ruger BX-25 features, strippable for cleaning, constant force main spring and identical lug dimensions.
