Ati pro mag install

[u/General_Friendship87]

Hi sorry for asking this very basic question but idk what I’m doing. Trying to install this pro mag but idk what to shave and what not to. Any guidance and help would be appreciated.

Just use a bit of strength and insert the magazine in on an open bolt, and remove it. You'll see what you'll need to remove for a smoother insertion.
