nicholastheczar Posted July 28, 2014 Share Posted July 28, 2014 I've been running a Hiperfire 24C with the 2lb spring for this season and have noticed I get quite a few bump fires with this trigger. I came from a CMC flat trigger and never had a single bump fire. I've called Hiperfire and asked them about this and was told I am holding the trigger to close to the reset point which then causes bump fires. Anyone else experiencing bump fires with this trigger? I'm running this on a 18" Nordic rifle length barrel with JP LMOS BCG and JP Silent Captured Buffer Spring with a Noveske upper and Gen2 lower.

TXMXRACER Posted July 28, 2014 Share Posted July 28, 2014 I have been having the same issue. I think its just me--being lazy and not gripping it tight enough. Only does it when I am trying to be fast on the trigger. Link to comment Share on other sites More sharing options...
gerritm Posted July 28, 2014 Share Posted July 28, 2014 (edited) You definetrly sounded like you went close to full auto, but you did have a fast time. I tried to match you, but could only go thru 42 rounds not 45. Couple of seconds slower. gerritm Edited July 28, 2014 by gerritm Link to comment Share on other sites More sharing options...

I'll try to post a video tonight of the stage, it was a quick 45 rounds. Link to comment Share on other sites More sharing options...
nicholastheczar Posted July 29, 2014 Author Share Posted July 29, 2014 Here is the video of the stage. I had two bump fires during the stage one right at the beginning where I had fired 3 shots and on the 4th shot it bumped a fifth and the other on the 3rd to last target where I had fired the second shot it bumped the 3rd - the rest of it was my over-active trigger finger. http://youtu.be/vEQ-b4_xQw8 Link to comment Share on other sites More sharing options...
LoganbillJ Posted July 29, 2014 Share Posted July 29, 2014 Bump firing is on the shooter. I have found I bump fire when not holding the gun firmly enough, kinda letting it float when really trying to push my speed. After doing a little focused practice, bump fires went away and times went down. Link to comment Share on other sites More sharing options...
Mberry Posted July 30, 2014 Share Posted July 30, 2014 Only time that it's happened to me was when one of my trigger pins worked loose during a match. I never believed anti-walk pins were neccesary until that happened, now I won't go without them. Link to comment Share on other sites More sharing options...

I never believed anti-walk pins were neccesary until that happened, now I won't go without them. I run KNS pins on my rifle just to make sure. I typically don't see the bumps on offhand or kneeling shots, more so on prone shots for me, which seems backwards. Like LoganbilJ said, I know it has to do with not holding the rifle in tight enough and the short reset of the Hiperfire trigger. I really like the 2lb springs on the trigger, but I didn't see the bump fire with the 3lb springs. Maybe I'll try it without the boot and see if that helps solve some of my bump fire issues. I really don't want to go to the 3lb trigger. Link to comment Share on other sites More sharing options...

Issue is when you get lazy and butt not firm against your shoulder it will bump fire. Pull the rifle into your shoulder pocket tighter and bump fire should go away. bgc Link to comment Share on other sites More sharing options...
