Long action and magnum AR's

[6.5AR]

Hello! Thanks for an awesome forum and website, I think I've come to the right place. Forgive me if this has been asked before, but I thought it would be nice with a subforum for long action and magnum AR style rifles for cartridges longer than .308. Would be nice to have a place to discuss parts compatibility and reviews. 

 

Some examples:

Luvo Arms LA-11 in 6.5x55mm or 7.5mm Swiss

Noreen BN36 in .270, win .25-06, .30-06, 300 win mag or 7mm rem mag

Noreen Bad News in .338 lapua magnum

Nemo Omen in 458 winchester

POF-USA P300 in 300 winchester

Petra Falkor in 300 win mag

To start off, magazine comparability seems to be a big one with these, as there seems to be quite a bit of variations in cartridge lengths in those mentioned.
