Leupold IMS Mark 4 Integral Base

by TRINCE, from SD, United States Written on August 23, 2016
I combined this base with the Leupold IMS Mark 4 1" insert to mount the optic on my 450 Bushmaster AR. I was looking for a solid, well-built mounting system that would stand up to the recoil, provide necessary height and clearance, and readily adapt to the picatinny rail system on my flat-top upper. This base filled the bill in every regard. Comes with all mounting hardware, including the four screws for mating the base to the insert, along with understandable instructions. Quality of the product was obvious upon first exam...typically Leupold. I'm glad I paid the extra money for a mount that I'm completely satisfied with. The mount fit perfectly and works great for my application. I'd buy another without reservation.

Solid base for the Mark 4 ring insert

by BM, Verified Owner from MI, United States Written on August 1, 2015
Solid base for the Mark 4 ring insert. 4 included screws come pre-coated with locktite. You need this if you are using the Leupold Integral Ring Insert Mark 4 IMS. It does not come with the rail. Use care to torque the mount properly.
Pros:
  • Solidly built
Cons:
  • expensive but worth it
Best Used for:
  • Mark 4 rings
