This is an ok kit.....but... - AT3 Tactical FU-BAG AR-15 Lost Parts Kit

I think this small parts kit is good in that it contains most of the parts that we typically need over time. My only problem was with the two "Takedown/Pivot Pin Detents. These pins fit in their respective bores properly - once you can get them in there. The ones I received were too long to get them into the roughly 1/4" hole that the takedown pin fits through. So I could not get them into place until I shortened them by about 1/16". That may be more than I needed to take off but I slipped on the grinder and that's about how much got removed. But after that modification they went in just fine.
