Secret Weapon bought a Herters model U9 .270 bolt action rifle at an estate sale. Fine looking rifle. Shoots great up to 300 yards. Trouble is the magazine spring is broken I've been online looking for one. Numerich Gun Parts ect. And can't find one. The rifles were manufactured by BSA in the late 60's and early 70's. Would any of you all know where I might be able to find another spring? Thanks
