Been hanging in the shop for almost a year since she was assembled. About time for the finishing touches. Bula Defense Systems rear lugged XM21 with Liberty SS 5R 1-10 .308 barrel finish reamed with M-118 reamer to a headspace of 1.633, SEI Vortex direct connect on the muzzle, unitized gas system set in a JAE chassis. Atlas bipod and Accushot monopod. Leupold Mk4 16X fixed. Looking forward to running her through her paces, maybe tomorrow. Snowing lightly now. Whatta Hobby!

Snowing, already?

Nice looking rig.

Yep, not enough to amount to much, but it was falling this morning.
Thanks, I do really enjoy putting these things together and making them sing. Whatta Hobby!

There have been some questions as to what a rear lug actually is on an M-14 type rifle on other forums. I pulled one of my Bula Defense Systems rear lugged XM21 actions out of it's stock so I could show what a rear lug looks like. Doesn't improve accuracy, but does tend to extend the longevity of a bedding job. This lug is drilled and tapped for an anchor but I don't use them, at least not yet, but always a possibility in the future. Whatta Hobby!
