mosin modification help

[Riven_Cole]

hey, sorry if this has been answered. i did a search first and all i found were threads saying this mod works and why/why not do it. not instructions, or pictures on how to do this "properly" (or at least as properly as possible) or at least better than the idea i have to simply grind down the cocking knob on the bottom

anyway i wish to convert my mosin nagants bolt to be able to cock on close instead of open. do not worry i am getting another cocking knob (and bolt body if necessary) for the modification so the originals can remain untouched. if anyone could help out i would be appreciative.

Why in the world would you want to do that.

Cock on closing went out of fashion somewhere around WWII because cock on opening works better, faster, and is safer.

Too many things can go wrong when you have a loaded round in front of a firing pin while the spring is being compressed against a trigger sear with the bolt unlocked.

dont mean to insult but...

perhaps i should make it clear that i do not care about the opinions on this. rest assured i am doing this for a reason and will be taking precautions to prevent accidents if you are concerned with injury. also it is my rifle if what concerns you is damage to the rifle.
i will be doing extensive testing before i even load a live round. if proper modification requires firing pin modification i can get one of those too.

If you don't care about opinions, why did you bother to post?

because i was looking for better instructions. i did not at any time ask for opinions. please do not take the following wrong but: if you are going to argue do not respond. it does not add anything to my request

The problem is it's tough to do without creating a potentially catastrophic safety gap. The thing can fire out of battery, without the lugs or the bolt handle in place. That means potential death, not just a cut hand and some powder burns.

I believe the main reason people have been doing this is the sticky bolt syndrome, but there are far better fixes for it. If you're just doing it for the heck of it, just be sure not to pass the modified bolt back into the stream of commerce. It should never leave your possession again.

But if you are determined, a fellow called Mooseman, an amateur smith from somewhere up here, claims to have done it safely and figured out how to block the pin. I would contact him on Castboolits:

I have noted several times when seeking instructions here in the GS forum, one gets negative opinions, and usually from the same people.

Usually due to the wisdom of many years' experience. Of course, not everyone takes kindly to that sort of silliness.

As it is, the member has been offered a lead of searching out a SAFE way of doing this, as well as significant cautions about the serious dangers of doing this.

We aren't going to host a conversation about a dangerous modification, so I'm closing this one. If the OP tracks down a safe way to do this and wants to share his results, once proven, send me a PM and we'll open this back up.
