This is a 3D printed plastic cover that slides on over the top of the standard Daisy 499 front sight.  It can aid a little bit with sight alignment by enlarging the front sight in the rear aperture. It goes on tight.

This is a version of our front sight hood that includes a wide bubble level.  It can help beginning shooters learn not to cant and help experienced shooters figure out the small things. 

This sight is similar to the wider model listed above, but the tube is smaller in length.  Some shooters find the wide level annoying and like to keep the front sight more round.

This is a team pack of 20 BB containers as pictured above.

This is a 3D printed tool for disassembly of the main plunger spring of the Daisy 499. You can attach a standard  1/2" PVC pipe to complete the tool. 

This is a classic "dope book" created for the 5 meter BB target. It is a great place for the coach to keep notes and keep track of sight changes.  It's also great for new parents trying to learn how to adjust the sights. Feel free to download and use.

This is an LED light kit that can you build to go around your BB target box.   It is especially helpful in the standing position where the LED contractor lights can't light up the target as you would like. 

This is a sight aperture set that lets shooter fine tune the front sight aperture size to their preference.  The sight aperture is also designed in the classic format with horizontal bars instead of the vertical post.
