Help with MPA PMR Rifle chassis install

[Codiekfx400]

This little black piece with a tiny spring attached to it fell out of my Mpa pmr Rifle when I pulled the action from the chassis. What is it? Also how and where do I reinstall it? The piece of 223 brass in the picture is just there for size reference. Thanks Codie

I figured it out it is the filler for the ambi bolt handle chassis. Lol

That looks like the plug/spacer that goes in the channel opposite side of your bolt, where the bolt would close into for a left handed rifle. Just drop into the space and spring holds it in place against the action.
