The Malcolm 8X USMC scope comes with Lyman style micrometer rear mount and front ring. In this video, we’ll be going over what you need to periodically check to ensure that the mounts work properly.
The Malcolm 8X USMC is externally adjusted. When the recoil spring is not used, the scope will physically move forward towards the muzzle under recoil.
This movement is due to the inertia of the rifle’s recoil. Over time, this constant movement may cause some of the mount screws to come loose.
We recommend that you check these following screws prior to any vintage sniper competition or hunt.
You may use blue loctite on both the top screw of the front ring and the set screws of the adjustment turrets. However, you will still need to check the screws periodically.
