Firing pin spring drag

[LVLAaron]

I have tried different springs. I know this should fall out and not have drag on the bolt body.

What can a guy do? Chucking reaming to embiggen the inside?

I've reamed them with a 7/16 reamer but I did it to install a Delrin bushing on the firing pin to prevent the pin tip from coming off center when cocked. I even have a Flex Hone to polish the bores. All that was prior to all the custom actions coming to market.

Is the spring snaking? Correct spring? Gre-tan offers some springs that are supposedly smaller OD. May have to buy the entire assembly.

If correct length spring, you could make a mandrel and using emery cloth, put in lathe take a little off the OD, then polish the spring.

Spring is straight. A new spring will drag if it's not on the assembly... just the spring. I'll check out gretan

I like the sounds of that and am embarrassed that I never did it! Did you see any positive effect? WH

Might be a good use of a flex hone!

 

[Ledd Slinger]

Not worth the effort because it will still never be as good as a custom bolt

A dingleberry ball hone from Brush Research is what I'd try first. -Al

Embiggen??

 

[Alex Wheeler]

Why is this a problem?

 

[GenePoole]

Embiggen??

It's a perfectly cromulent word.

 

[marazzi59]

Or try running some sandpaper

Cromulent, can you take penicillin for that?

Tagging in for the result

As I understand it, a dragging spring can affect lock time consistency.

Curious, what’s that bolt out of?

Tonto said to LR when his teepee raised "embiggen"

 

[dirtworks5]

The concern is forward movement of the pin not the removal of the assembly.

While you are figuring out a solution, remember that thing only moves about a quarter of an inch.
