I'm filling out my Form 1 for my SIG MPX and wanted to know what OAL to put down.  It will be completed with the SIG telescoping stock.

Thanks!

21", I went by the cutout in the case, It measures just a little shy of 21" which would give it a snug fit in the case.

OAL is messured with the stock fully extended.

I stand corrected, however they will bump it back to you with a range of lengths, many have got their forms back with one measurement or the other, but not both.

Anyone have a measurement with the SIG stock extended?  Looking to get the paperwork sent it since I'm probably looking at a 3 month wait just for the stock.

Thanks in advance!

Sig's website lists MPX overall length as 22.8" with collapsible, collapsed length as 18.1".  Looks like OAL with folder is 24.0" and folded length as 16.7".  22.8" seems like the best OAL to use unless some other non-Sig stock is part of your plan.


Edit because I mixed up the numbers

Add 1.5" to those specs as Sig is using the original 6.5" barrel length.

I already received my tax stamp on my form 1 converting the MPX-P to a SBR by adding the telescoping stock. I used overall length of 22.8 inches. Everything worked out fine. Now I'm only waiting for Sig to send me my telescoping stock that I ordered on June 2.

For those of you who have received your forms 1's back already-- what did you put for the Model? I've seen conflicting posts about using 'SIG MPX' (as it is engraved on the pistol), or just simply 'MPX'.

Thanks!

When I ordered some mags and the telescoping stock from Sig, the rep told me the oal of the 8" Mpx with the telescoping stock was 25.25".

I went through this thread looking for the Form 1 specifics, but couldn't find them. If someone with an approved Form 1 could please post what you used for name, manufacturer, overall length, etc... I would greatly appreciate it. There are too many Form 1's getting rejected because of stupid shit, so I would appreciate the help...

Thanks!

That will be ok, I got my back for a correction, CLEO put his name as maker instead of mine, and SIG MPX was not highlighted.
