SVI vs STI guide rods

[dansedgli]

Anyone know if these are the same?

The SVI one has notch down the centre of the back of it closest to the barrel link. The STI one doesn't.

 

Can I interchange them?

 

The 2nd hand SVI I bought recently seems to have a 2 piece unit that unscrews itself.

I am using an svi guide rod in my sti edge. No problem.

I do not believe they are the same.  I believe the "button" on the rear is different size and I know the diameters are different at least on the commander length guns.

 

Edit to add: It might be an age of the gun type thing too... the more time that has passed since the split, the more SVI seems to change their proprietary specs.

Thanks guys. I pulled a tungsten guide rod out of another STI I had and it had the notch too. It seems to work fine. 

 

Its pretty old but it shoots well. Well worth the price I paid.
