I just picked up the MFI low pro mount for my SP5 SBR. I have to say that this is by far one of the best aftermarket mounts I’ve seen and used. In the military we were issued the HK claw mount and it worked great to be able to still retain the use of the irons. I was definitely not going to spend the asking for that mount or the HK Factory Mount. I went on a search and found that most of you were using this exact MFI Mount and were very happy with it. If you don’t know which one I’m referring to click on this link https://mfiap.com/i-23899698-mfi-spe...insurance.html it will take you straight to it. I will need to mount my Aimpoint Micro to it and go zero it this weekend. Thank you for helping me decide on another alternative to the HK factory mounts.
