Description

Upgrade your AR15 with the QUATTRO-15 Lower Receiver and the QUATTRO-15 Magazine by DesertTech. The receiver itself features a drop-in design, and is compatible with all standard AR15 upper receivers. Once installed, QUATTRO-15 Magazines can be used, but standard AR15 magazines can be used as well with the use on an adapter. The only proprietary parts are the magazine release and bolt catch, other than that, the QUATTRO-15 Lower Receiver is compatible with all other standard AR15 parts.

The QUATTRO-15 Magazine on the other hand is a quad-stack magazine with a capacity of 53 rounds. The benefit of this configuration is the ability to carry more ammunition with fewer magazines. For example: four QUATTRO-15 Magazines can hold 212 rounds, while seven standard magazines will only hold 210 rounds. This translates to more shooting and less reloading. To overcome the issues often faced by quad-stacked magazines, the QUATTRO-15 Magazine utilizes a simple yet highly reliable single follower and a single spring design.

Features of the QUATTRO-15 Lower Receiver:

  • Compatible with all standard AR15 upper receivers
  • Allows the use of DesertTech’s QUATTRO-15 53 round magazines
  • Only proprietary parts are the magazine release and bolt catch, compatible with all other AR15 parts
  • Can accept standard AR15 mags (with the use of an adapter)

Full Ambi controls, grab the adapter plates, and you are set. The only proprietary parts on this are the Mag Release and the bolt catch, everything else is normal AR lower parts. I don't personally care for the rear set screw to snug the upper to the lower, I prefer accuwedges or ear plugs or similar instead, as it keeps things tool-less and depending on the grip installed the set screw ends up covered up, but leaving it out doesn't hurt anything at all. Qmag works fine with 223/556 and 300blk. With the adapter plates installed, the cmmg 22lr kit runs fine, 762x39 runs fine, and even endomag 9mm runs fine. So even if you aren't sold on the Qmag side of things, with the adapter plate you've got a very competitively priced full ambi lower.

This lower and mag kit is awesome! Lower assembly with standard AR parts was a breeze. The mag loads fairly easy, but it's a shame DT hasn't designed a LuLa style loader to make it easier and faster. After assembly to a 16" upper it went to the range where it performed perfectly. There were absolutely no mis-feeds or problems of any kind when emptying the entire 53 rds. After installing the magwell inserts everything worked as well as it did with the DT mags using g.i. aluminum, Magpul, ETS, and Wilson 30 rdrs. One of these days I'll try a Magpul D60, and I expect it to work, also. In all, I couldn't be happier with the performance, and really like having the extra rounds in a mag that is no longer than a standard 30. This is quite a package!!!
