Upgrade your AR15 with the Desert Tech QUATTRO-15 Lower Receiver and the QUATTRO-15 Magazine by DesertTech. The drop-in design of the receiver ensures compatibility with all standard AR15 upper receivers. Once installed, the QUATTRO-15 Magazines can be utilized, but standard AR15 magazines can also be used with the aid of an adapter. The only proprietary components are the magazine release and bolt catch; otherwise, the QUATTRO-15 Lower Receiver is compatible with all other standard AR15 parts.

The QUATTRO-15 Magazine is a quad-stack magazine boasting a capacity of 53 rounds, offering the advantage of carrying more ammunition with fewer magazines. For instance, four QUATTRO-15 Magazines can hold 212 rounds, while seven standard magazines will only hold 210 rounds. This results in more shooting and less reloading. To address common issues associated with quad-stacked magazines, the QUATTRO-15 Magazine incorporates a simple yet highly reliable single follower and single spring design.
