Both of my Boyd's Axis stocks had their inserts crack and they sent me replacements right out. But it sucks knowing they flex and crack in the first place. I ended up replacing them with aluminum ones and steel pillars...sooooo much nicer, although pricey. I am also worried that my Axis Hardwood .223 will have its crack as well. Those are Boyd stocks and the insert seems a bit different and glued in place. I really don't want to have to chisel that POS out of there.
