Benelli Adjustment Tube Part 166S for M3 or Supernova Collapsible stock.

 

This is the adjustment tube so you can convert to a collapsible stock.

Hey hk, I know I've been bugging ya about the part, but why does the tube appear to be parkerized from the photo?

[heckler&kochp2000]

Not sure, I think they come like that.

Hi HK,  I know this is an old thread but is there still a possibility to get the 166s adjustment tube/rod?  I would love to modify my M3 Super90 to fit a telescopic butt stock. I already have the butt stock but can't install it without the missing tube...... Thanks!

Have you checked your tube?  My M3 Tactical came with the tube.

I unscrewed my original pistol grip buttstock and yes there is a tube but it's not notched to accept the adjustable buttstock.  So really need to change the original tube to the 166s tube with the notches.....  I might be wrong though.... maybe others can pitch in...  if it's too much hassle to work on then might just well abandon this option..

Depends how old your M3 is, there's different tubes for different M3s.

Here's a pic of my disassembled M3 Super90....  the tube rod is fixed but I think this was just locktited to the mainframe.......  i don't know if I can unscrew it though... seems very tight and won't budge....

 brought it around 2012 or so maybe................

Oh man, that’s a slug scope M3 with chokes! Those are incredibly rare in America; I’ve only seen one other american person have that barrel on their M3 ? unless you live elsewhere….

So you can go two ways with your M3 - either get the entire back end of the M1014 on it or use the M4-A1 / NZ M3 combo. The tube should be a high strength thread locker so concentrated heat needs to be applied for removal.

Thanks Doge for the heads up.   I think I'll just keep this stock as is and maybe buy an m4 instead.....  hehehehe

Hi Doge, just would like to ask if this would fit on my M3 to be able to change it to telescopic stock? Do you think it would fit (screw) on the back of my unit after I take off the original recoil tube?  I don't know what the M4-A1 / NZ M3 combo piece you're referring to.... do you have a pic of that?   Thanks!

There's no official documents about parts and stuff for the public, so I am making this up as I go:

The NZ M3 uses the plastic stock originally from the Supernova. It is also shared with the newest M3-A1, MR1, M4-A1, & GLX160. It is special because they reuse the M1014 grip. 

 

The tube you have posted should work with your M3. The back end should be threaded for M21 x 1 screw threads. As long as it doesn't say H&K on the side that's a good indicator it has the M21 screw threads. You would just need to use the M1014 grip. It is squared on the back to line up with the M3 receiver.

You can look at stock shim kits to see the different shape. The curvy shim won't work with your gun; which also means the curvy the grip won't work. Some people bubba the grips on and they mismatch.
