## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Took forever to get here but...
  

*by S***R on Reviewed in the United States on March 15, 2021*

...but it's a great fix for an old primer that wouldn't seal or prime.  If your primer isn't working, the rubber on the plunger is probably stiff and wore out.  Get this and your priming problems will go away!

### ⭐⭐⭐⭐⭐ 







  
  
    Original replacement part
  

*by A***R on Reviewed in the United States on April 2, 2020*

Accidentally cracked my plunger and was so happy I found a replacement at a normal price!

### ⭐⭐⭐⭐⭐ 







  
  
    Worked perfect on a 404!
  

*by N***E on Reviewed in the United States on January 20, 2020*

My 404 primer finally broke in 2019 after years of service. This replaced it and worked great.
