British S.A.S Mp5 what model?
 

I've been watching some videos on the British SAS tonight and I noticed something different from the typical mp5 airsofts I have seen.

The barrel of the gun is more rectangular than most of the ones i have seen that have that typical triangle/slope look barrel.

What model is rectangular barrel? I've included a picture to show what im talking about

I'm not sure what you mean. Do you mean the SD, integral silencer versions?

I've read many books and watched plenty of my share of documentaries on the SAS.

For the MP5 variant they utilize the MP5 SD6.

Manufactured by: ICS, JG, TM, G&G and Classic Army.

edited with red blocks to clarify.

This picture below is the slope/triangle look im referring to

That's the navy wide body if Im not mistaken.

I think the one im looking for is the MP5A3.

seen here: YouTube- H&K MP5A3

Now to find an airsoft version :)

Yeah, TM produces one called the MP5-J or the Mp5 "navy"

I think HAW has one.

From what I understand you're looking for the old cylindrical hand guard.

That's actually an old style of MP5 early to late 1970's IIRC, no airsoft company or after market company (or atleast that I can think of) makes that specific hand guard. Classic Army does make the old A3 lower receiver though.

Classic army BT5 Wide forearm MP5A3 or whatever it's called is like that.

oh poo :(

Hand guard is the standard MP5 one not the retro style MP5 version, but yeah that is probably as close to the old MP5.

Here's one, I think a couple guys on here even have these.

I think he's looking for a regular MP5 foregrip guys.
Nothing special.

Remy, they come standard on most airsoft MP5's.

I think he's after the narrow (rectangular) vs. the more common wide (triangular).
