Titanium from rxarms.com

Thank you to everyone who responded. Issue resolved, operator error! I thought I had pushed in far enough, but apparently not. Thanks for the hints and Don for the video posting. And to Robb at RX for the great looking and “locked in” knob!

New m4. Handle was fine. purchased a bigger titanium handle. removed stock handle and put new handle in and it would not engage and stay in. Tried to put stock handle back in and would will not engage or stay in as well. Any ideas? Thanks in advance.
