SIG MCX VIRTUS 1/2X20 Adapter

Note: Remove the factory thread adapter and measure for the proper thread size. (If the thread size is smaller than 9.6 mm in diameter you will need the version 2 adapter)

You have to remove the factory threads first. The factory thread has two flat sides where they can use a wrench to turn it counterclockwise to remove. Then add on the DonnyFL adapter.

Features:

• Compatible with .177 and .22
• 6061 Aluminum T6
• 1/2 x 20 male threads
