I have a model 12 lrp and bought a bolt lift kit for it off a guy on snipers hide for a model 10. The bolt assemble screw on my model 12 has a small cylinder shaped nub on the assembly screw. Does the model 10 have the nub on it. Reason I ask is this nub is what contacts the ballbearing. Does the model 10 have the nub?
thanks guys
Models 10 & 12 use the exact same bolt. As well as all the others. Save for a few that use the Axis style bolt....which doesn’t apply. Of the classic model’s bolts, they can use the same lift kit. There are a few different lift kits. But I still like the DIY kit.
There are a couple things, in addition to the lift kit that really makes the whole thing work very well. Smoothing/polishing the cocking pin ramp, is imho, a necessity. I also lighten firing pin spring. But would not rec. unless you know exactly what you are doing, as you risk light primer strikes. I also use a Silicone Nitride, ceramic ball bearing in mine. But my bolt is only polished, and does not use the nub. My bolt lifts with one finger after trigger release. SUPER easy! Love it.
Chief, I think you are describing the cocking indicator that goes through the center of the screw. If this is the case, the lift kit will not work.
Ahh, Rob has a point chief...I was thinking you were referring to the “nub” on some lift kit BAS that is actually an adjustment. But now I’m thinking you have the other style bolt, (as Rob said). Can you post a picture of what you have?
I see it serving no purpose. It is solid machining flaw I believe.
Yeah, your fine chief. That is a standard BAS. And yes, that little “nub” is a simple machining flaw. It’s common for sizing screws. The screw is spun while a Tungsten Carbide bit is introduced into the threads, cutting it flush via radial material removal. Any bolt lift will work on yours just fine.Quote:

Took off the nub and polished to a mirror finish. Works great.
Good move! Exactly what I did. And yes it does! Hey chief, you seem fairly handy...have you, or are you planning to smooth the cocking pin ramp? It really does add. My bolt lifts easier than any I have felt. Obviously, it’s well known that Savage rifles typically have a stiff bolt that is not very fun. Mine lifts with one finger and steady firm pressure.
Never seen a BAS with a nub on it. Parting tool was below center line. Or it was dull.

BTW...Robin, I know you GET all this my friend. I’m not trying to “educate” those who do. Just talking out loud for those who may not.
Cause we know I've never used a part off tool... Well maybe an Iscar once or twice. https://sdthumbs.ui-static.net/t/mae...100&height=700Quote:

After thinking about it, you’re right....either situation could create said flaw.
Iscar makes nice stuff! Very cool...
