RE: Encore or Pro Hunter???
It means you only have to turn the plug 90 degrees and it then comes out like the breech on an older piece of artillery.. on an older Encore you have to screw out the plug not a big deal takes less than a minute and you only need to do it when cleaning. I'll put it this way, it is not worth it to me to buy the new barrel with the easy out plug because my rifle works fine as is but if it had it I would love it.
You need to get out to some gun shops and check out these features and see what you like. If you find a good shop that helps answer your questions and has what you want in stock reward them by buying the gun there as long at it is not priced way above the box store. Us shooters need to keep local shops alive as long as they are not out to rip us off. They need to charge a bit more than the big stores but having the local support especially you being new to BP is worth it.
