NO ISSUES with Impact guns packaging,shipping or order processing!!
This Is an alloy!! So dont expect the feel of aluminum or plastic. INSIDE the box the manufacturer states in writing ALUMINUM LOADED MAGNESIUM ALLOY Lower! YOU CANNOT PAINT OR GRIND/SAND ON THIS LOWER!
All milspec parts I slapped into this /dark earth/ receiver Fit just like any other receiver. Just middle of the road parts too. I paid for the dark earth colored lower, all else I added on! .223/5.56 Upper slapped on it. Its an extremely light lower. I poured about 150 rnds through it to this point. And no issues!
I admit it almost feels like ceramic, but the magnesium/aluminum combination is used on alot of aviation parts, such as landing gear wheels and those take tremendous beatings over and over. So I was put at ease knowing that, even though the lower felt ceramic and way lighter than any I own now. I would buy another without hesitation....and after reading some other reviews of this lower the demand for these seems to be increasing with US forces.
