| Is it possible to reduce trigger pull, safely and effectively, on a std. mil. trigger just by manipulate the stock springs, or would replace springs be ok. |

[url]http://www.ar15.com/forums/topic.html?b=1&f=74&t=149423&w=myTopicPop[/url] I have done this on all my rifles except one. Only negative effect is that my .22LR conversion kit is now less reliable. Using all kinds of .223 ammo, I have yet to have ANY light primer strikes. |

All right, I tried the modifications that FALARAK provided and the trigger pull has definitely been reduced, but now there is some creep in the trigger. I need to find out if this is normal. I tried Brownell's as per Amish-Bill suggested, but they were out of stock. I'll report back when the kit are in stock. |

Reduced power springs won't reduce trigger creep, but it will reduce pull weight. To reduce trigger creep, you'll need to stone the sear surfaces, or if you're not comfortable with that, use polishing compound per the instructions provided. It's a military trigger, so some creep is normal. If you want a match trigger, buy a match trigger. |

Big_bear, When I try the Brownell's springs, I will used an unmodified trigger and hammer. Before I perform the mods(included everything listed per instructions), the std. trigger had no creep what so ever. Now there is a fair amount of creep, but I do not know if it is excessive or normal. I am not sure if I want to polish the sear anymore and take it to a point where the unit is unusable. As it stands right now(without going to the range), the trigger functions properly. What I do notice though, when engaging the trigger, there is about 2mm of creep. During this period of trigger movement, the hammer moves in a downward motion (in towards the receiver). Then BAM! the trigger breaks, very crisp and clean. Total trigger movement is about 4mm at most. I had a few inert primers, so I made some dummy round last night(10). Fire each round and compared the primers afterwards. To me, all the primers looks as though there was plenty of force generated by the hammer and firing pin for primer ignition. Real concern is about the creep. Thanks |

I did the above trigger modification and was happy with the results compared to what it was before. But...I have some trigger creep also. Being that I have tuned my bolt guns to a 3lb. let off with no creep, I'll be getting the JP adjustable trigger next pay day. Rambosky |

Military triggers are a tossup. Sometime you get a golden one, sometimes you get a bear. 2. You did have this same amount of creep prior to doing the trigger job. The length of engagement surfaces has not changed. What is most likely, is that you could not notice this creep previously, since it took a lot more weight to get your trigger in motion previously, and once you applied enough pull weight to start the trigger in motion, it was one quick pull all the way to where it broke. Reducing the pull weight would make this much more noticeable. 3. You aint gonna mess that trigger up by polishing using the process provided. Only way you would mess it up, if you manually stoned the surfaces, and then went too far. Using compound and trigger/hammer movement would take a VERY long time to eat through any amount of metal. However, no matter how much you polish, you aint gonna change the amount of engagement surface to any strong degree. 4. This operation just greatly helps a lot of triggers. It sounds like your particular one is less than favorable. As Big_Bear said.... if you want a match trigger, buy one. I'd recommend the RRA 2 stage for $95. |

I have (4) RRA 2-stage triggers, (2) in my CMP service rifles and (2) in my NRA match rifles. I love them. FALARAK, I understand about the creep prior to the mods, it make alot of sense. It's not that I am unhappy with the uncome of the mod( I am actually very please with the reduced weight), I just want to make sure I did it right and that others have had similiar experiences. What's normal for an acceptable amount of creep? |

Wow, I just did this trigger job to my ar15, and wow. It was quick, easy, not too messy. My pull now is nice and light, and smooth. I know an aftermarket trigger would be better, but this job cost me $2.99 (for the No7 compound.) I recommend this for anyone. Great DIY tip. Austin |
