Okay Guys, have been reading here a lot the last couple of years, but never needed to post much; as the search button has always been my friend and I enjoy reading more than posting. Until now...

I purchased a Stag Model One at the end of this past summer. Today I decided to change out the grip. When removing the grip, a slender 1" spring fell out onto the work bench as I pulled the grip off. I did not recognize it so I immediatly checked the parts manual and could not identify what this spring was for.

Here is where my ingonarance comes in... After inspecting, I mistakenly deduced that it was a tensioner spring for the screw that I took out to remove the grip. I put the spring in the hole and attached the grip. This was a mistake. After checking for an empty chamber I attempted to move the safety and it would not move. I then took of the grip and saw that the spring was "mangeled" in the safety lever.

Before I contacted Stag to show my stupidity, I thought I would show you guys first.

Any ideas what this spring was for?

Thanks for you assistance.

See the link below:
The spring is #21, there should also be a detent pin, #20
They are there to hols the safety selector in place and it provides
the detent action for the safety.

Thank you both. The detent pin is still in place. I have ordered a new spring.

Yep, the spring pushes the pin into the safety lever to give it that nice click and resistance when you select your fire modes: Safe-Undead-Outbreak

There is a similar pin when you take off the buttstock that has a bigger pin that pushes against the rear takedown pin. It holds it in place so when you pull it out to open up the gun, the takedown pin stays in place instead of just coming right out.

The AR is a very simple weapon really, when you get down to it.
