This is a nice and functional Castle Nut Wrench made out of .110" steel. It has the standard 1911 barrel bushing release cutout on the end opposite to the castle nut spanner.
These are the same wrenches that we include in all of our launcher expansion packs and with the top break Tac-79 in the tactical configuration.
The wrench fits very securely into the notches in a Castle Nut. The ID of the spanner is perfect. I mention this because such a good fit is not often found in an inexpensive wrench.
As an amazing extra bonus, all of these wrenches now sport the Ordnance Group logo. Get a couple, toss them in your carry tool kit and range bag.
Made in China by contented workers.
