| Cock on open bolts are dumb. Why? Cock on closing is so much nicer (enfields, various mausers, etc.) Anyway, shooting the RAR, I have to hold the rifle down to open the bolt after firing. Can't really remain seated at a bench of a bag or bipod, since you gotta wrestle the rifle to chamber the next round. I could easily carry the rifle around all day with the closed bolt, and the firing pin down, and it would never open with just the weight of the rifle. Maybe 15lbs of lift to cock the firing pin and open the bolt. Can I reduce this by repeatedly cycling the bolt (close the bolt with the trigger pulled, and then lift, repeat)? Any other fix? |

First thing I would do is take the bolt apart and see if the cocking piece is broken. Ruger had issues with that if I recall right. They changed the design at some point and there is also an aftermarket fix. Next I would check the rear stock bolt and see if it's interfering with movement. CLP would be fine by the way. |

This ^^^ https://www.anarchyoutdoors.com/ad-arms-billet-ruger-precision-american-rifle-cocking-piece/ Don't forget the firing pin removal tool if you don't have one. Changing out the cocking piece is an easy swap, there are videos on YouTube showing the bolt disassembly if you've never done it before. |

Mine have all been a little rough but nothing that has bothered me. Thanks for the replies. I think I'll try polishing the cooking ramps. It's definitely cocking the firing pin that's causing the resistance, because lifting the bolt with the firing pin already cocked is fine. If that doesn't work, maybe the aftermarket cocking piece will do it. |
