Fostergp's Review of Killer Innovations Icon Defense 308 Drive Lock Hanguard

Locked up tight even drilled the anti rotation pin myself. Heights matched up with aero m5 (standard) upper. Worked with .750 riflespeed gas block. Did not work with jp thermal dissipator. At least not normally I turned it down small enough to fit. 1.3 internal dimension
Pros:
  • Solid lock up, sturdy, durable finish
Cons:
  • Small Internal dimension but large enough for riflespeed gas block
Would Recommend: Yes
