Welcome to Survivor's....
It's customary here to introduce yourself before simply posting numerous questions; most folks also post a pic of their rifle and tell us a bit about how they came to own it, etc.....
As a new member, I would urge you to read the forum rules carefully, and use the search feature at the top of the page, which works very well.....
By simply coming on as a new member and asking abrupt questions from your very first post, you are walking into what is essentially our clubhouse and being rude.....
So please, take a second , introduce yourself, get the feel of the place, and enjoy the atmosphere a bit.
