Big improvement over the stock springs.

Works as advertised. Installs easily after modification of bridle. The whole job took around 15 minutes. TTN bridle screws threads on my shotgun are pretty crude. Recommend using blue locktite when reinstalling them.

Easy to install, nice replacement, some fitting necessary.

Spring works great. Down side is cutting/grinding a small internal part. After I did that, all was OK.

These replacement springs work perfectly.

Just installed Saturday to shoot today. Made a good change in the triggers

They work great. Installation is easy once you get the stirrup filed to spec. The 1st stirrup I hand filed, took some time. The second one I did 90% with dremel then finished with file. Springs are working great. I’m also using the extended firing springs and the top lever springs. I reallly wish Slix would make main spring.
