Classic 'Mag sear/bolt durability

[JKR]

Recently, I have seen a few postings about "gun going full auto" and questions concerning worn bolts and it raised the question in my mind: How many shots can be fired through a Classic 'Mag before the bolt and/or sear wears to the point of needing replacement?

Well, I bought my mag used 3 years ago from a friend who had bought it used one year earlier, so my best guess it's at least 4-5 years old, if not older. No sign of excessive wear on the sear, although it had an aftermarket bolt, and now lvl10, so I don't know about that.

I'd agree with that.I don't think I've ever changed a sear that was simply worn from use.The Bolt is SS and is softer than the hardend steel used in the sear.I've seen a few chewed up bolts from improper set up or swaps but never in a mechancal.

As long as you just shoot the gun and do routine maintenance of cleaning the gun, those components will last the lifetime of the gun.

The bolt is designed to be softer than the sear because it rotates as it cycles, so the wear is spanned out over the circumference of the bolt, whereas the sear has one contact point.

The #1 reason why those parts wear out is because people mess around with the gun by adjusting the trigger rod and installing aftermarket parts.
