Sure there are plenty of posts. But can't search 'mdt' or 'lss'

So. I have a long action, bottom bolt release & detachable mag.

Looking at the LSS or LSS XL

I have a full varmint profile 26" barrel the rifle is pretty front heavy, how are these for shooting off a bipod?

These use AICS mags? No other mods needed, just drop in the chassis and good to go?

Any other info would be appreciated.
