It will look just like a G36 and work the same way, but with M16 magazines.
Two years ago I almost bought a SL-8, but the mag restrictions caused me to move on. Wound up getting a different rifle, and then into NFA weaps because of that choice.
Thanks for the good info HKP7PSP - nice username, too. My fave 9mm pistol. Accurate as heck, shame it heats up so fast.
