Caius Posted October 23, 2010 Share Posted October 23, 2010 I have an old M1 with the original rear sight. The screw sheared off and I'm trying to get a replacement part or find where I can get the upgraded sight that they went to if anyone has any info it would be appreciated.

i_wish Posted October 23, 2010 Share Posted October 23, 2010 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. http://hkpro.com/forum/showthread.php?126041-HK-M1-Benelli-M1-Question 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: http://www.precisionsights.com/Product/BAR_product_page.html 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. Quote Link to comment Share on other sites More sharing options...
