Tank's HD Magazine Spring, 12ga

These high quality magazine springs eliminate feeding problems caused by weak and worn out springs. This is especially true in semi-auto's.

Tip: The indication of a weak magazine spring is when no shell has fed onto the carrier but shells are still in the magazine. Springs should be replaced every 400-500 rounds or when the spring has shrunk over 3" from its original free length. Approximate free lengths are:

7-shot----------32"

8-shot----------34"

9-shot----------37"

10-shot--------40"
