If you're looking to speed up loading for your .22 LR magazine and save yourself a sore thumb, then the McFadden Lightnin' Grip Loader is the ticket! However, you'll need a specific loading adapter that's tailored to your particular .22 LR firearm, and McFadden Loaders has a ton of them available! Of course, you have the adapter for aftermarket 10/22 magazines, like those from Butler Creek, Shooter's Ridge, Ramline and more, but there are tons of other options available. Have a Smith & Wesson M&P15-22? There's an adapter for that. What about a Ruger SR22? There's an adapter for that. Maybe you've got one of those Kimber 1911-22 conversion kits. Guess what? There's an adapter for that, too! No matter what .22 LR conversion kit or dedicated firearm you have, there's a chance that McFadden Loaders has a specially tailored option for you. All you have to do is find the right one for your gun, and you'll be loading those empty magazines almost as quickly as you shot them empty!
