Ruger 10/22 FRT Mars Trigger (Page 4 of 4)

Enter the Bore Buddy anti bounce bolt. I installed one of these last night and slow motion video shows the bolt bounce is gone! The action also sounds much better. I have zero doubt now that this will run reliably in reset mode. The Bore Buddy bolt is expensive at $400, however the quality is excellent. The bolt appears to have more damping mass than the Norrell bolts. Additionally all internal corners of the bolt surrounding the anti bounce weight are radiused generously so cracking shouldn't be an issue as occasionally reported with the Norrell bolts. |

So I just did my first 10 round mag dump. The first mag I tried was loaded with Winchester 45gr super suppressed but it shot one round and did not eject the fired casing. So I tried some CCI mini mags and it shot a 10 round mag with no issues. I haven't put the supplied recoil spring in it yet. Is the spring that comes with the kit a stronger or weaker spring? Wondering if it will help with the subsonic loads. |

I just tried some CCI standard velocity and it ran them ok. I tried a 15 round mag and it shot all but the last round. It stove piped the 14th fired round and the 15th was in the chamber. I would assume that is possibly from the bolt not traveling far enough back to get positive ejection but it was far enough to strip the last round in the mag? |

"ETA - Put the 8" barrel and re-installed everything else. Suddenly, a lot of bolt bounce issues. This was with both CCI Blazer (HV) and CCI SV and with a can." The Bore Buddy anti bounce bolt corrected all the problems I was having getting the Mars trigger to reliably work with my 8" barrel 10/22 |

The Bore Buddy anti bounce bolt corrected all the problems I was having getting the Mars trigger to reliably work with my 8" barrel 10/22 I have a spare Norrell bolt with anti bounce weight which I'm going to try with the MARS and 8" barrel. If that works I'll get a Bore Buddy. Maybe that'd work with my Norrell gun too. I just thought it was interesting I had no problems with the MARS trigger until I went to the short barrel. |

Integrally suppressed and now goes Brrrrrrt. Definitely save the slave pin that comes with the MARS trigger. I pulled the MARS trigger out with out putting the slave pin in  . That liitle spring that goes into the trigger is a bitch to get back in. |

A couple of slow motion videos, first of a stock 10/22 and second with a Bore Buddy bolt. The stock bolt bounce is what makes these so challenging to get running with a reset trigger. September 20, 2026  September 20, 2026 Edits: clarity |
