H&K Benelli M1 Super 90 Rear Sight Replacement


Recommended Posts

My buddy has an HK marked Benelli M1S90 and his has the older style GRS. Mine isn't marked HK but has the LPA GRS on them. Are you trying to replace the complete GRS assembly? I don't know if there is a retro fit but there was a thread on another forum showing that the mounting holes don't line up.


You would have to tap newer holes to switch from the older GRS to the LPA GRS. I have read many horror stories of how the older GRS suck. They would fall off and also in your case, the screws shear off.

Here is the websight for the LPA USA distributor:



you can also get them from brownells but I believe they are out of stock. You can also find the replacement parts at Brownell's too. Good Luck and let us know how it goes.
