As advertised

Went on my new M3K just fine. Took a little dexterity to get the screw through but not bad. Never got a shipping confirmation (which I like to check a lot! When I order something. But did not matter because all the stuff came within 2 days!) Response- Confirmation email is sent as soon as it ships, maybe check spam box. USPS tracking number is put in your order online, UPS tracking will be emailed when package is picked up.

A must for all 3 gun shooters!
