Overall Customer Rating of 70 Reviews:

This Spring Works Great

This is my second Mossberg SA-20 and trigger spring. The first SA-20 was stolen by hood rats. Before you fire the first shell, you need to install this spring. Shooting is much more enjoyable.


Mossberg SA-28 Trigger Spring Kit

Works as advertised. Only negative is the install video does not show that the trigger linkage assembly needs to be removed. On the re-assembly, it is shown being put back in place.

Mossberg SA 20 Spring Kit

I had a problem with the first kit and customer service responded immediately and sent a replacement. I was able to achieve a 30% reduction on my SA20 from 7 lb 4oz down to 5 lb 2 oz. Shipping and customer service are first rate. I highly recommend supporting M CARBO.

SA-28 spring kit

Super easy install after watching video, trigger pull went from 6 1/2 pounds to 4 1/2 pounds, super happy with this kit. Great deal.

SA-08 Trigger Spring

Worked as advertised. Dropped my pull weight down from 7+ to about 4 lb. and took out the nasty creep. Would definitely recommend for this particular trigger.
