I have a used Carter Target 3. It has been used for about 2 years and has been very reliable. The reason for selling is that I changed release aids. It was last serviced in October and only shot for another month afterwards. Currently set up for left-handed users but remove the barrel and turn it round, hey-presto it's then set for a right-handed user. No box or instructions are included, but there are plenty of instructions online and on YouTube. 

This release aid has been minorly adjusted where the red paint has been removed to curve the edges on the grip as it was very "blocky" in comparison to my other Target 3 release aid. This doesn't affect use and makes the release aid feel much nicer to grip.
