i just received and installed a new flatwire buffer spring from david tubb in my ar, (carbine length buffer tube) and upon installing i was unable to manually pull back the charging handle/bolt without a lot of what i would call "extra" force. if felt as if the spring was binding or the bolt wasn't being allowed to move back freely. it was almost impossible to pull the charging handle back far enough to get the bolt to lock back. i've read some posts where people have been told to cut coils off the the spring, but there is nothing about this on the manufacturers website or on the packaging of the spring. (which does state it is an ar 15 spring, standard and carbine .
i'm disappointed to say the least. i was really hoping this would work out as my ar is overgassed and i'm beginning to play with some different springs and buffer weights. has anyone heard of or had the same kind of experience with the tubb flatwire buffer spring? |
| and yours was also a carbine length buffer tube? i didn't really lube mine as it states the spring has a hardcoat lube applied to it. i know a lot of people have these in their rifles, that's why i'm surprised i had a problem. i wrote tubb an email, we'll see what they say but as of right now i can't run this spring |

Did you bother to contact the mfg before dumping on them in a public forum? This is what a public forum is for. He is not dumping on them, just asking for more reviews basically. Most of the time, it's easier to get info from forums than wait for MFGs to respond. |
| i didn't realize asking others what their experience has been was dumping on the manufacturer. i did contact them and they have already emailed me back asking if i had test fired the rifle - which i have not. it might simply be that the spring is brand new and needs to be worked in a little bit - which i also understand. i was hoping to read here on the forum about someone who has gone through the same exercise, to see what the outcome was...i didn't find anything so i decided to post, not just to ask the question, but so that when others look to find answers they'll be available by what we've discussed here. |

What the hell are you in a forum asking us questions?!? I run flat-wire springs in all my ARs and I did have the same situation happen to me. I took it out, scratched my head, swapped it with another rifle's spring and it (both Tubb's springs) cycled fine. Swapped them back around and they were still both working. I cannot tell you why it changed but I will say I would NOT cut the spring. Call David's shop first. While you wait for them to open, pull it out and put it back in a few times.

The shorter tube adds more preload to the spring.
They feel strong, but mine cycle with no problems. Don’t cut the spring. If it is truly binding then you probably did something wrong. Post a picture of the buffer out of the weapon with the spring installed. It is metal on metal so I lube mine, but that would not affect what you are talking about. |

why am i asking questions? are you serious? i assume "what the hell" really means "WHY the hell"...where else should i go to ask other AR owners what they're experience is with a flat wire buffer spring?
I also said i had heard of people cutting springs, i have no intention of doing that...and i also did send an email to Tubbs and they have responded. Sheesh the spring i purchased was for an AR15, "standard or carbine" - it's the same spring. the spring is much longer than a typical carbine buffer spring, but supposedly the collapsed height is shorter, so it works. so i don't believe i'm trying to cram a rifle length spring into a carbine buffer. the spring was fully seated onto the buffer...it actually snapped onto the larger "shoulder" of the buffer, so i know that's at least installed correctly. there's not a lot to get wrong when installing a buffer spring. i had also ordered a blue sprinco spring, which i wanted to try. that installed just as easily and the charging handle will work the bolt back easily...so it's the flat wire spring that's the issue. I plan on shooting the gun with the flat wire...but i can almost bet it will short stroke. maybe it will wear in....but that just seems strange to me. |

Out of curiosity I collapsed a Tubb’s flatwire spring on a CAR buffer by hand, there is plenty of clearance.
Greater force needed … yes. Binding … No Almost impossible to pull fully back … No. This is a CS spring it will take many thousands of rounds to make a noticeable difference in the strength of the spring. I have these springs on 16”, 18”, and 20” barreled weapons using H2 and H3 buffers with FA carriers. All three weapons reliably cycle AE 223 REM ammo. |

It was a facetious question relating to an earlier posting insinuating that asking questions about a product problem on forums is wrong.  Hope it all works out for you.

Must have been mine. It wasn't the question, it was the last line that looked like bashing. I know better than to judge intent, so to OP I apologize. |
