Thanks for all the input guys...lots'o wisdom in the counsel of others...

I had been mentally fixated on a short LOP...I just figured that I shoot AR's really well with a shorter LOP so why add length to a gun I don't want or need...

I took the LOP test...the one advised above...and came up with the number I had been fixated on the whole time...13" So 13" it is...time to break out the straight edge adn pencil and adjust the table saw...

BTW, whoever mentioned the LimbSaver grind to fit recoil pad in another thread...AWESOME...
