I was a new owner of this rifle in January of this year. I spent about an hour each night for about a week reading and skimming thru the majority of the posts on this forum and learned a lot.

Spend some time reading, and you will be glad you did. Especially read thru the stickies and watch the videos for good explanations of how to work on the gun.

Get the barrel wrench. It is $20, and worth every penny.

Buy extra magazines when they go on sale. Have at least six, IMO. Ten would be better.
