power tube spring??

[Shiftee]

i was reading the "Questions about a used 68AUTOMAG" thread and was wondering if i have a power tube spring instead of a solid spacer does that mean mine is a level 6 ... and what difference does it make?
thanks.

No, when the level 7 mags came out they came with the spring. IIRC, it was a couple of years before the spacers started to appear (first as an aftermarket add-on).

Also IIRC, Level 6 mags had the power tube held on with a c-clip.

thanks dude

so what difference does the spacers make?

Spacers allow you to "tweak your trigger" and also help cure leaks down the barrel and also bolt stick. You change them out with a shorter or longer one depending on the problems you're having.

Bolt stick put a longer PT spacer.

Leaks down the barrel put a shorter one in.
