.180" Tall x .125" wide. Part No. 020-024. I had this fitted on my Operator and changed them out to experiment with another front sight that I picked up. The gun was never fired after the sights were fitted. Both the front and rear angle of the dovetail were filed to fit properly on my Operator. The sight comes in the original packaging with an aluminum drift punch and replacement red and green fiber. Disclaimer: The fit on your Springfield may vary but should be close. Add some Loctite if you need and you're good to go. $25 shipped.
