Open up your upper, so you can look down into the lower receiver.
1. With the hammer cocked, make sure the selector rotates from safe to semi.
Note that the rear tail portion of the trigger should be in the down position.
2. rotate the selector to semi. Pull the trigger to slowly release the hammer (do not allow the hammer to slam forward onto the bolt catch, this can cause the receiver to crack if done repeatedly) look for the rear tail portion to rise up into the selector.
Now try to rotate the selector to the Safe position. It should not rotate.
If it does rotate, take the rifle out of serves and consult your local armorer.
3. Disconnector. With the trigger pulled and held to the rear. Cock the hammer. which will be captured on the disconnctor. release the trigger and the rear portion of the trigger will drop down and also release the hammer for the disconnector onto the trigger. The selector will now rotate to Safe.
Now that you know what to look for and feel for, you can perform the same safety check with the upper put back in place utlizing the charging handle to cock the hammer.
I hope this helps and I hope that it is a simple case of the hammer was never released thats why the selector was rotating on your Colt.
In the sport of combat, there is no second place.
