Shimanski tells us that most people go to a gunsmith for stock fitment? Replacing the stock and woooing it as a new model is just like what her department does? Why not refine the timing and bolt lift. The Axis style firing pins and springs do help some and I';m sure they will find their way into all models eventually but htis is the lipstick on the pig scenario. I like the stagger fed models anyway....and lets do control feed while we are there.
