The Tippmann Arms Speed Loader will load your magazines in seconds, perfectly every time.  Not only does it load Tippmann Arms M4-22 magazines, but it will also load M&P® 15-22, Rock River Arms, and Black Dog X-Form Magazines.  Simply load the hopper with 50 to 100 rounds of your favorite .22LR ammo, gently shake the rounds into the track, and crank the handle to load.  The Tippmann Arms Speed Loader will not damage the lead or casing like other speed loaders.  With every crank of the handle, one plunger pushes down the bullet stack and another loads the round.  It's so smooth and fast you'll hardly feel it working.____________________FEATURES:Compatible with:Tippmann Arms M4-22 Magazines M&P® 15-22 MagazinesBlack Dog X-Form MagazinesRock River Arms .22LR MagazinesBlack Dog V208 MagazinesGen 1 CMMG MagazinesFor use with .22LR Ammo OnlyAmbidextrous Crank Handle
