I’ve been lusting after the Phase 5 Weapons Systems ATLAS ONE billet receivers ever since they introduced them a while back. A few months ago they introduced their billet upper and just yesterday they released the ATLAS ONE billet lower. I honestly had forgotten just how sweet this thing looks. Not only does it have some pretty sexy lines it also features the Phase 5 signature WTG (Winter Trigger Guard) built in and has a really great looking finish. These receivers are typically used on the ATLAS ONE AR Pistol which is Phase 5’s flagship item. Now you can purchase them too to use in your own builds. Take a look at the pictures below, then head on over to Phase 5 to buy some for yourself.
