last night my dad bought a speed loader for his AR-15. But, he was quite skeptical about it so I told him I would beat the normal time of loading a clip with the speed loader. He timed me several times using the speed loader and then just my hand. I got a time of 28 seconds putting 20 rounds in his clip using just my hand, then for the speed loader I also used twenty rounds and got a time of 33 seconds. I tried over and over to get it under 30 seconds but, I could not. It is more comfortable using the speed loader. It is more of a finger saver, not a speed loader.
