Waiting on more info from Mark at PF but he says the 20" Bartlein meets my specs (HBAR with .750 gas block OD).
I asked about a 22" instead but I think I will be happy with 20".
Waiting for his reply on the 22".
The limiting factor is the length of my Lancer Rifle Plus handguard at 13 to 14 inches.
With a bipod mounted near the end, it is supporting the rifle where it should.
Adding inches would extend the barrel muzzle further from the bipod and add an additional bending load on the barrel boss of the upper. (Really heavy barrel)
So I think 22" is my upper limit.
I can't help myself always thinking of the engineering aspects of it, it's a habit of my occupation.
So here's what Mark recommended for $690:

Mr Lilja I am very appreciative of your willingness to offer your help here, and I may indeed end up with a Lilja instead.
If not for the Grendel, perhaps for my AR10 (DPMS Spec).
Thanks again,
Will post when I lay down a deposit ...... the Shilen is definitely out.
