Bibliophile Posted April 9, 2021 Share Posted April 9, 2021 (edited) Yesterday, after installing several updates, I took the M4 out for a session of spirited shooting with its' brothers. Everything went well, with a few TBD items cropping up (mostly Loctite-related), but one issue has me perplexed so, before I screw something up, I figured I'd ask your opinion here. The issue is around my recently-installed GG&G Tactical Bolt Release. After about 50 shots when I switched from bird shot to slugs (limited availability of 12 Ga. here), I began to notice that the bolt release pad was getting progressively more difficult to depress. After shooting all 5 slugs, I examined the gun and noticed that the spring is now sideways (see attached picture)! It was normally positioned before I left, and the M4 was able to perfectly cycle 12 Ga Snap Caps with no problem. So - question 1: what holds that spring in place? I must have messed up something, but was careful and didn't lose any parts/pieces when I installed it. And, question 2: best recommended way to put the spring properly back in without removing the bolt release? I don't have any more roll pins and was hoping to be able to put it in there with minimal disassembly. Thanks for any guidance or advice you can provide. 20210408_171309285_iOS.heic Edited April 9, 2021 by Bibliophile Removed accidental duplicate image Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted April 10, 2021 Share Posted April 10, 2021 Chances are you didn’t get the spring seated properly in its little notch. The latch pivots on the pin so it isn’t a straight in and out sweep when the latch is moving around. This picture might help you see where the spring should be set: 2 Quote Link to comment Share on other sites More sharing options...
Whiskeydog Posted April 10, 2021 Share Posted April 10, 2021 This happened to me as well, though it got so bad that the spring was completely deformed. A buddy gunsmith of mine theorized that the spring that came with the GG&G bolt was a different tension then the factory spring and that's what led to the spring coming undone. We put the stock spring in and I've had zero issues since. 1 Quote Link to comment Share on other sites More sharing options...
Bibliophile Posted April 10, 2021 Author Share Posted April 10, 2021 Thanks for the good information. #StrangerDanger - is that the GG&G-provided spring, or the OEM spring in your picture? Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted April 10, 2021 Share Posted April 10, 2021 I used their supplied spring. I don't know if it is a different weight. Like maybe they calculated the weight of the pad into the spring rate? I'd guess either would work fine once set correctly. 1 Quote Link to comment Share on other sites More sharing options...
webnit65 Posted October 14, 2022 Share Posted October 14, 2022 Have any suggestions where I can purchase a replacement spring? Same thing happened to me and warped it, Thanks Quote Link to comment Share on other sites More sharing options...
StrangerDanger Posted October 14, 2022 Share Posted October 14, 2022 You might be able to get one from GG&G. I'm not sure if the spring weight is different than the OEM one. You could reinstall your OEM one in the mean time to see if any issues arise. If I had to guess, I'd assume they were the same. Anywhere else you'll be buying an OEM spring anyway from places like Brownels, MGW, or Numrich. Quote Link to comment Share on other sites More sharing options...
StreetSweeper56 Posted October 14, 2022 Share Posted October 14, 2022 I have 2 of these GG&G bolt releases and have never had a problem so I am with SD in guessing the spring wasn't seated properly on installation. I used a pair of hemostats to hold it in place as it was difficult with normal size fingers; worked like a charm. Quote Link to comment Share on other sites More sharing options...
truckcop Posted October 14, 2022 Share Posted October 14, 2022 I've hade a couple of the GGG's installed for at least 10 years now, if not more. I don't remember even getting a spring from GGG back then. As I recall, I used the OEM. Quote Link to comment Share on other sites More sharing options...
webnit65 Posted October 14, 2022 Share Posted October 14, 2022 Thanks all for the advice. I ordered 3 springs and a roll pin from Midwest Gun Works so I have extras. Quote Link to comment Share on other sites More sharing options...
