[MossyMilDot]

$13.99, 2/20/2014

My old Mossy 500 (35 years old) magazine spring had no spring left. I might have been able to stretch it out, but for $14 ordered one of these delivered. Learned my magazine tube just hands turns off (good to learn).

I am impressed.

I've heard nothing but good about them. Do they improve performance over new OEM?

Great, glad its working for you! Yes the magazine tubes (usually) just unscrew. If not its time for the heat gun!

I've always liked Wolff. Probably OEM for a lot of guns.

They are stronger. My OEM spring was dead and 35-years old so not fair to compare them. I can load 5 shells and they work great.
