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!
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....
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..
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!
