The Mil-Sport is made from quality forged 4140 aluminum, and is built to take anything you throw at it. Introduced in 2012, the Mil-Sport M4 Carbines became instant hits among customers looking for top quality AR-15 style rifles with forged aluminum receivers. Fine-tuned with many popular features, these U.S. built beauties perform perfectly right out of the box, and are priced just right.
Ordered on a Friday and it was delivered the following Thursday. Sighted in with 20 rounds of Winchester 125 grain 300 Blackout. No jams, no misfires. Nice overall feel. Enjoyed shooting. Nice gun at a nice price.
This ATI Milsport 300 Blackout exceeded my exceptions. Have only run a couple clips of Magtech 115grain HP. So far it runs great and seems to be very accurate. Only complaints I have are easy enough to fix if your handy.
Hand guard is just a tad out of alignment with the upper housing. The 6 screws holding he hand guard in place are thread locked. So heat them up before attempting to unscrew.
= Plastic trigger, hammer, and upper/lower assembly pins. They seem up to the task, but only time will tell.
