This is what you'll need to give it one. Bear in mind that some do ship with the detent installed even though they have a tacked on muzzle nut.

Good kit!

It's a good kit, the pin seems to be holding really tight after install. The detent and spring seem to fit very well, and moves smoothly and easily.
Continued use will show whether it's reliable or not, but so far, so good.
