Designed specifically to fit the HK MP5, HK94, Bobcat, SW5 (9mm) / HK93 & H&K 53, C-93, V93 & V53 (.223) / HK91, HK 41 (NOT MSG90 Style Mounts), HK G3, CETME, PTR91 (.308). These have windows cut to see serial numbers on HK MP5s and V53 Pistols.
This mount differs from our Regular 5.5" Long HK Low Scope Mount ONLY in that it has 2 WINDOWS / SLOTS cut in the top in order to see the Serial Numbers on HK MP5s, SW5s and Vector 53s. All of the aforementioned have serial numbers stamped on the top of the receivers. Cutting these slots was a direct request from our Law Enforcement Clients who have to see the serial numbers in order to check them in and out or the weapons lock up area. In most cases the entire serial number is 100% visible. In a few occurrences like on the SW5 it all depends on where they stamped the number. The worst I have seen is on a very early SW5 where you could not see the very first digit. All MP5s and Vector 53s that we saw have numbers that will appear near the center of the slots. The MFI Low Profile Slotted Scope Mount is the ONLY low profile mount on the market that does not require the mount to be removed in order to see the serial number.
This mount is the ONLY UNIVERSAL scope mount available for all 5 calibers of the H&K MP5 / HK 94, HK93 and HK91 style weapons. So YES all 4 center fire calibers: 9mm, .40 S&W, .223 and .308. We currently have these in the supply chains for all Theaters of Combat Operations including: Iraq and Afghanistan not to forget Law Enforcement / SWAT Teams and Private Military Contracts like BLACKWATER / "Z" throughout the world. So if your Supply Officer does not have any we can sell them directly to you.
