Here's what I did to mine:
I placed mine in a Boyd's stock, bedded the receiver, installed pillars, and free-floated the barrel.
Added a Timney trigger, scope mount and glass.
I just cut the barrel to 22" and gave it an 11 degree target crown but haven't yet gotten her to the range to try it out.
2-1/2" groups at 200M with handloads.
Handloading is probably the best way to improve accuracy over the milsurp ammo.
