Kevin's Review of 2A Armament Builder Series AR15, Aluminum Billet Trigger, Guard Slotted

As other reviews have stated the screw holes are completely out of spec. It is impossible to install this guard on a mill spec lower receiver without modifying the receiver or the trigger guard. DO NOT BUY.
Pros:
  • None
Cons:
  • Junk
  • does not fit receiver
Best Used for:
  • Throwing in garbage
Would Recommend: No
