If you look close you will see it and that is the place I had ours welded. My pre-64 rifles are one solid piece. Any way, after reading a couple times of those pressed on collars spinning loose on the bolt body and hearing of a well known gun shop that uses "Classic" actions for their expensive rifles welding theirs up, I followed suit.

Hey Josh,
I have been using Mag-Na-Ported rifles and hand guns for over 30 years to help control muzzle jump.


Thanks much for the clarification! "Bolt handle collar" versus "bolt sleeve", better description for dummies like me! smile That simplification makes perfect sense compared to whittling down one solid right angled mass! Such, of course if it doesn't beak loose! smile
Best!
John!
