Three other conversions which won't require a new stock are the Kwik-Klip, HS Precision, and Badger that uses Accuracy Int'l magazines. Of the three, the Kwik-Klip looks more like a sporting rifle and fits flush. The other two are more military looking, and the magazines protrude. The AI mags are the best quality and feeding of all, but you might not like the looks of them on a sporter rifle.
