Navy specification weapons?

[Scotty Dog]

Just an odd one; can somebody explain why some firearms come in a Navy variant and what differences there are? e.g.. PPQ Navy, MP5 Navy etc... (real steel stuff)

Its something that i've never been able to work out!

Is it simply to do with the spring cups and some extra milling work? Or a tougher finish for salt water resistant? Or simply nothing to do with the Navy?
Its been playing on my mind, so if someone could offer a nugget of knowledge I would greatly appreciate it!

Cheers,

Scott

They come with extra lube.

Depends on the gun, for example the P226 Navy has a corrosion-resistant finish on its internals with navy markings on the slide while the MP5 is closed bolt and has a safe-semi-full trigger group with pictorial markings as opposed to numbered or SEF known as a navy trigger group.

The original MP5 Navy was built for the US Navy (probably their special forces groups), and had various changes made to suit their needs.

the list of changes are:

• The introduction of the ambidextrous, pictogram marked "navy" trigger group/lower receiver - this is now a standard on all new production mp5s, but just having a navy trigger group does not make an MP5 an "N" variant
• A tritium front sight for low light use
• A threaded barrel for use with suppressors - there was a suppressor made for this configuration by knights armament.

Other weapons may have other changes. remember that each weapon system has it's own charecteristics, and so will require different things to gring it to what the navy need out of thier guns. (for example, the MP5's standard finish at the point the N was introduced seems to have been good enough, while the 226N has a special coating)

There's also a "Maritime" or "Marine" version of lots of weapons. Interesting to read into. Perhaps more interesting is the sort of things that are cut out on the regular variants to save costs.

From what I know it does depend really on the specifications that they ask for. In some cases it can be corrosion resistant finishes due to use around water and others it can just be a design that the Navy wants because they can.

In the case of the MP5N it is not just the pictogram receiver that was added (that was an option before hand) but also a few other things like the 3 lugged barrel for quick release suppressors and other attachments. It is really just a group saying 'we want this gun with these bits, thanks'. Many groups do it and make changes, things like the Beretta when they found the slide cracked after a fair few rounds got made into the 92FS which the US Army took as the M9.

Same could be said for the MP5SF and MP7SF variants, the semi auto 'carbine' models that are used by British Police due to restrictions on full auto weapons. They are something specific that HK offers as a model as it proved to be popular among countries that need them.
