Our AR springs kit consists of the following (1x unless otherwise specified).
We include extra take down and pivot detent springs, as during the
installation of a carbine end plate and castle nut, the spring can
easily be bent.
Buffer retainer spring
Selector detent spring
Disconnector spring
Bolt catch spring
Port cover spring
Mag catch spring (10.9 in/lb, extra spring rate)
Forward assist spring
Hammer spring
Trigger spring
Take down / pivot detent spring (x4)
If you're like us, you might have plenty of factory hammer and trigger pins, or just don't need them because your trigger already comes with them. It is now possible to substitute the hammer, trigger springs and disconnector springs with something that seem to go missing when needed: an extra safety detent spring (x1), and two take down/pivot pin detent springs (x2). This flexibility is a no cost option.
