I just got back my Colt AR-15 A2 lower from Mac's shootin iron and am VERY pleased! I wanted it to match my Colt M4 upper so I had them do the lower in Matte Black. Firrst here's how it looked originally in Colt Gray with wear & tearBEFORE
after only 3 DAYS they shipped it back looking like a brand new receiver!AFTER
the finish is slightly rougher in texture and harder, more sturdy and resistant to scratches. They did the receiver and all it's internals. total cost with shipping: $65.00 quite a bargain.
now I feel like I graduated to the big leagues having an all factory Colt M4A1 (as you can see, I'm still waiting for the pivot pin adapter from Bushmaster) I can't wait to fire this baby on the 4th of July!Mac's Shootin Iron Restorationswww.shootiniron.com
