I've got a 7" one that's NOS.. Has the Smith Enterprise installation instruction sheet and is marked NSN 1005-01-506-8160 UNITED STATES PROPERTY.

Funny thing is...the -506- is described as a 5" mount and the -533- is described as the 7" on the installation sheet

BTW... Looking to sell it soon

Thanks from russmerle

The most common version seen on military M14s is the 5" version, which is NSN 1005-01-506-5750. It was used on the US Army M21A5 rifles beginning around 2003-04, and on the USMC DMR and M39 rifles beginning around 2006-07. (That NSN was created in April 2003).

I don't get a hit on the US Army property look-up with NSN 1005-01-506-8160. I think SEI offered it as an option with their M21A5 rifles - in case a longer rail was needed for night vision gear, etc. It is also possible that individual soldiers bought that mount as SEI went through the trouble to get an NSN for it, but it doesn't appear to be an official procurement item like the shorter 5" version - at least not that I can see. Its definitely a mil-spec mount, but unclear if the military procured it. So if one is trying to build an accurate 'clone' of an M21A5, USMC DMR, or M39, I would recommend the 5" version instead, but otherwise that 7" mount should be a good one for just about anything else.

Thanks from russmerle and RDS
