    Everything works great and they give you a decent amount of parts for the price. I would rather see a couple other parts instead of the trigger pins. I usually get them with the trigger already. Would be nice if the plunger and spring for the bolt catch were included.

  • I haven't used it but it looks like a well thought out kit. Nice to have around

    Bought this because no one seems to include pins/springs when you buy "Enhanced" lower parts. and now I'll be buying another just to keep the parts on hand. There are other companies that have these kits but I'm glad a company I'm familiar with offers the kit.

  • Great common AR parts kit at a great price!

    I recently purchased a Geissele AR lower parts kit and was in the process of building an AR platform when I suddenly realized the Geissele kit was missing a single plunger pin. I thought about calling Geissele about it but imagined how much more hassle it would be dealing with this issue through them than just buying the oops kit from Aero Precision, so I ordered one. It arrived soon after I ordered it and I was able to pull from the kit the plunger I was missing and quickly finish the build. The kit comes with two each, of the most commonly lost or misplaced pins, plungers and springs of an AR build. The springs and pins visually appear to be well finished and of great quality, however some of the plunger pins appear to have small imperfections which could lead to malfunctions or rough operation but since there are two of each, you can pull the ones with the best finish or try to polish or correct the ones that are a bit rough around the edges. All in all, you cannot beat the Oops Kit in a pinch, it is an absolute life saver and a fantastic product offering by Aero Precision!
