I have had no problems with my ATI collapsible stock,I have used it on a 243 standard contour & 357 mag handi combo and It has been on my pardner 12 ga that has a 18 inch cut barrel.I only shot it about 25 times with the 12 guage because the recoil on a 3 1/2 lb 12 ga is unbearable no matter what load your shooting,Its perfect for the 357 a nice light rifle that balances well but its still a little front heavy.Maybe Im just lucky It hasnt broken down after 4 years but if It does break I will buy another I will also let you know if it breaks and share some scope bite pics,Heres a pic of the 357 with the collapsible and some tasty venison from last year 154 yards with federal fusion 158 gr factory ammo
