Correct Part For The Job!
I tap and use these screws in the takedown detent hole in the rear of AR receivers. Make assembly of carbines much easier to accomplish.
5
Perfect fit
As already stated by another reviewer these set screws are a perfect match for Aero Precision lower receivers that have the threaded takedown detent hole. Im going to buy more due to them being so tiny.
5
Perfect for Aero Precision lowers
If you have a gen 2 aero precision lower receiver this is exactly what you need for the rear takedown pin detent hole. Aero lowers come pre-threaded for a 4-40 set screw. Simply cut off and remove a small piece of your detent takedown spring to compensate for the length of the 4-40 set screw. Remove 2.5 to 3 rotations of the spring with a wire cutter or similar tool. Install carefully so that you do not lose the set screw and or send the spring flying. The allen wrench needed is 0.050

Great Product
I use these as a modification to the rear takedown pin on my ARs. These set screws are durable and solid.
