The Lightest Lightweight AR Lower Receiver
The MAG Tactical Systems GEN 4 lower receiver weighs in at 5.8 ounces. That’s more than 3 ounces (35%) lighter than an aluminum lower. MAG makes the part from their own nickel-based alloy and finishes it with a patented coating process.
The coating process is an integral part of the part’s design, so if you plan on having your lower engraved as an SBR or with a custom logo, you’ll have to return the raceiver to MAG to be recoated. They told me the cost would be about $25 plus return shipping for the service.
We saw black and tan samples that looked and felt any other commercial lower, aside from the dramatic weight difference and exaggerated trigger and hammer pin holes. MAG includes longer pins to accommodate the reinforced hammer and trigger pin holes.
