I have a Del-ton DTI Extreme Duty and it runs any magazine I put in it. The only concern is with green tips (M885). They sometimes need a bit more room than the plastic mags have and the aluminum mags have a thinner wall so they will not drag on the way up.

The Del-Ton comes in a hard case, and is supplied with a thirty-round C-Products magazines, which is a fine choice.

Magazines have come a long way in reliability. Many great mags to choose from such as Magpul, Lancer, D&H, C-Products, ASC, LaBelle, Colt just to get the ball rolling. Find the best deals and stock up.
