Original U.S. Military select fire kit. This kit is complete with the selector block and pin, selector switch and spring, and the connector arm with spring and plunger.
These are in excellent condition and in cosmoline. The small roll pin that attaches the selector switch is 1 inch long and can be cut to make extras (they get lost easily). Does not include a selector lock.
Ideal for making a dummy selector for your semi-auto M1A, or for use on a registered M14. All NFA rules apply! These selector kits are getting difficult to find.
