great little kit

Everyone who has an ar15 should own at least one of these kits. Great to keep around just in case.

Missing two takedown pivot springs

by -

Takedown and pivot springs are too large and don't fit the lower's holes! Maybe its my lower but it's my third one .Its a PSA . I lost the rear takedown pin, spring, buffer retaining pin and spring and ordered this kit .Buffer retaining pin and spring fits fine . Rear detent pin fit fine - dropped right in - tried to drop the spring in and it was too big. I thought I had the wrong spring thinking it was for the safety in the grip but that's the same size. I pulled the pivot pin out and looked at that spring definitely smaller and dropped right in like its supposed to . So I believe the kit was just a fcatory error and gave me three springs of the same size - Missing two takedown /pivot springs . Will contact customer support to see if I can get those separately ...

Excellent....

The kit is worth it for the trigger pins and springs alone. Great to have around.

Saved my but when I lost the forward take down pin detent. Would recommend to have on hand when building or repairing.

Glad I bought this...

Came in handy when I sent the front pivot pin spring detent flying across the room at about 100mph. Lots of great parts to have extras for. Wish more companies made kits like this.

An Absolute Must Have

by -

I absolutely love these kits. Great idea Anderson. Whenever they're in stock, I always pick up a couple. You never know when you're going to use something from it, but it never fails; I'm always pulling something out of the kit to use! I keep an Oops kit in my weapon's case(s), as well as my shooting bag. It's definitely saved me on several occasions at the range, during competitions, and even on a couple of hunting trips!!! Great, convenient and absolutely practical. You definitely can't go wrong picking up a couple kits. I guarantee, you're going to use most of the parts eventually, especially, if you build your own AR stripped lowers - in that scenario, it's absolutely worth ever penny!

Thank you.
