“This is the first publicly printed AR lower demonstrated to withstand a large volume of .223 without structural degradation or failure,” Wilson wrote on Wednesday. “The actual count was 660+ on day 1 with the SLA lower. The test ended when we ran out of ammunition, but this lower could easily withstand 1,000 rounds.”
Already, he says, over 10,000 people have downloaded the lower CAD file, with more on BitTorrent.
The guy with DD said that right now it costs them about $100 to make one 30 round magazine.
Awesome! Isn't the lower the most difficult part to actually develop? The barrel shouldn't be too difficult, right?
