With the bolt out of the rifle, the safety accidently got bumped to the forward, ( firing ) position while I was going to remove the pin/ sleeve assy from the bolt body to give it an initial cleaning . It got bumped forward just as I had the bolt locking plunger depresed and was starting to unscrew it. It now will not budge back , whether the firing pin is cocked or not. The locking plunger on the side of the bolt is not stuck.. Ideas ?

I just picked up a used Winchester 670A in very good condition. It has the 3 position safety, but the bolt will lift with the safety in the furthest rearward position . Once there, the safety does work ( blocks the striker ), but I was under the assumption the bolt was also locked with the safety all the way back. The striker is also blocked in the middle position, as it should, and the striker will fall/ fire with the safety off ( fully forward ) . It does not appear to have been tinkered with or abused. Was it possible to modify this ? Something broke ? Thoughts ? Thanks

How many broken Winchesters do you have?:D I do not know on the 670,but on pre-64 when the safety is pushed to the rear most position,a small pin moves forward from the bolt sleeve into the root of the boot,locking the handle.

Jim, I got the safety to move back to the middle, and was able to dissasemble the bolt for cleaning. I just now noticed that the bolt will open with the safety all the way back. I had made a new thread for this, but it either got removed or added to this.. Everything seems to work fine besides the bolt not locking.

I know a buddy's 670 will lock the bolt with the safety all the way back in the 3rd position. Just like the Model 70s. So something is not right. What I cannot tell.

Maybe the pin I mentioned is missing/broken? Again,I am not sure if the 670 had this feature,but if it did,a whey to tell is to unscrew the bolt sleeve again and look at the front of the sleeve for a small pin that will go forward when the safety is fully back,engaging a small recess in the bolt root.

It appears I remembered wrong about the safety on the 670. I got curious and looked in my "Bolt Action Rifles" reference book by Frank de Haas he states the 670 safety does NOT lock the bolt. I apologize for bad info.

Runningman, not a problem whatsoever . I appreciate you getting back to me on it, and you & Jim trying to help this 'ol guy out . I got my 1st centerfire rifle in 1972 ( Rem 700 ADL in 25-06 ), as a 14 year old pup , and since then have owned other bolt action, hi-power rifles.. Rems., S & W ( Howa ? ), Ruger 77's, Mossberg, Savages, O3A3's, Mosin-Nagant.. likely forgetting some, but this is my 1st Winchester bolt gun . I'm glad there is no problem with it, but am wondering why the deviation from other M70 bolts.
Jim, I did take the FP assembly out again to look where you advised. With the safety in the middle position for removal, there is a pin that is just flush with the " root ", or base of the sleeve . This is i'm sure, the pin that does lock the M70 bolts. What function it has in the 670, I have no idea. Winchester states, and others have advised, not to move the safety lever once the pin assy. is out of the bolt body, because I understand it's a bear to get it back together . So, I do not know if this pin in the sleeve moves when in the forward or rearward position. Thanks again, fellas.

When I said root,I meant the base of the bolt,not the sleeve. The sleeve does have the pin though,and you should see a small recess in the bolt itself to engage the pin. As far as reassembly the M70 with the safety off is no different then other bolt guns are, its much easier with the firing pin held in the full cock position. I hold the firing pin sear against something flat and solid,like the jaws of a vise,push the pin all the way back,and rotate the bolt body into place,rather then the sleeve.

Jim, I think we are talking about the same pin /sleeve scenerio. The pin is there and flush with the face of the sleeve. I do see the recess on the bolt you speak of. It apparently just does not come forward for some reason to lock the bolt. So, having said all this, and it being a 3 position safety, I'd think it would / should , have the bolt lock feature . Maybe something is amiss after all, but since the safety itself works, I'll probably just test fire & not fret about the lock. The bolt handle is a little sloppy with the safety on, but the action locks up very snuggly , and there is no slop or lack of tension with the handle when in the firing position. Thanks
