Does anyone have any experience/ used one of these? If so what is the feedback/review of them? Pro's/Con's? Should they be used with std buffer or heavy buffers? Looking to do some testing to see what buffer/ buffer spring combo works best in my .223/5.56 16in mid-length gas system and looking to see if this is something I should mess with or just save the money?
thanks |

I dislike them a lot after using one caused me to have serious cycling problems. Going back to a mil-spec spring fixed everything and I have put thousands of rounds through the gun since with no gas system related problems. No reason to use one of these springs ever. |

In a full-size 20-inch National Match rifle I recommend it (ISMI wire and not the flat wire).
I tried the carbine-length spring and it was way too long and caused a double boat-load of stoppages. I recommend a stock GI carbine spring if using a collapsible stock. |

What were you using it in? A carbine? Probably needs coils cut. I run 2 in rifle length set ups. A definite improvement. |
| Mine was running fine with 16" barrels in .223 and 300 BLK. Yesterday I tried it in my 8" 300 BLK with a standard carbine buffer (3 ounces)...too much spring tension to allow the upper to function properly; bolt would go back far enough to function properly. Put back in the standard coil spring and functioning was once again perfect. |

I kept cutting coils off but the problem persisted until it was extremely short (almost too short). I finally just threw it out. If there was some insane performance to be gained from it, I suppose I would give it another go but... It's minute at best. |

So what exactly are they suppose to do vs. what they actually provide? Meaning smoother action? less felt recoil? faster follow up shots? WHAT is the purpose of this spring vs what it actually does and how much difference is there over a standard carbine buffer spring? I've read what the manufacturer says it does but looking for experience of what users found with it? thought I put this in the orginial post but this is for a .223/5.56, 16in barrel w/midlength gas tube carbine rifle with collapsable stock and has a spikes tactical comp. Yeah I know, what mess around with fancy buffers/buffer springs when recoil aint that bad anyway but after shooting Army guns all my life looking to trick out "my baby" as best I can and just looking for best recommendations to trick it out without breaking the bank.
With Tubb's springs are folks running std buffers, H1, H2, etc.? |

With Tubb's springs are folks running std buffers, H1, H2, etc.? I tried all three of the buffer weights you listed with the same short-stroking issue. I still have an uncut Tubb's spring that is very lightly used that you're welcome to have if you want. PM me your address. You can evaluate it for yourself. I did not like it but if this spring helps you out, I'm happy to give it to you. |

The material advantage is that it lowers the cyclic rate and increases forward bolt thrust and rearward resistance. In theory it should reduce recoil, but I can't really tell with mine. Suppressed I can still hear a sproing, but it isn't quite as pronounced as the standard spring.
If your rifle is blowback, this can have some definite benefits when combined with a heavier buffer to delay the ejection slightly and keep the round in the chamber for a little longer to prevent some gas and pressure bleed. If your gun is DI and isn't overgassed or having cycling issues, the benefit will be minimal and can (like some said) cause reliability issues. |

I use one, flat wire, and like it. Midlength, carbine buffer, carbine extension. No more sproing sound. Basically what it does differently is that the flat wire gives the spring a larger range of consistent force. It has the same force with the bolt closed as with it at full compression, whereas the standard round spring oem will have a higher force at full compression. That causes a slight increase in cyclic rate. |
| the whole point why I'm looking at the Tubb's buffer is recently tried a JP enterprise buffer with a H2 buffer and it seemed it cycled slower but slammed forward harder than with a std spring with both std buffer and H2 buffer? The whole point is to lessen recoil as much as possible while keeping cycling as smooth as possible. |

The whole point is to lessen recoil as much as possible while keeping cycling as smooth as possible. Again, it isn't just the buffer and the spring. You have to look at the entire wt of the bcg and buffer, resistance of buffer spring, and the gas as well as the round being fired. Switching between springs is not going to do much, switching buffer wts is the biggest change besides adjusting the amount of gas and a compensator. Keep playing with various springs if you want but the biggest change is going to come from buffer and gas, if not the gas alone. 3gun shooters have the smoothest running rifles out there. The biggest thing they do is run adjustable gas systems and run comps. My 3gun rifle uses a standard carbine buffer, mil-spec spring, LMOS bcg, JP comp, and adjustable rifle length gas. About as smooth and least amount of recoil/impulse possible. |

I moved to Brownells standard-weight chrome-silicon springs & have had no problems. |

I'm running one in an A2 game rifle with an M4 stock and it runs fine. Buddy ran one in his M4 in Afg with the 173rd Rangers and fired hard enough in one engagement to melt the sling off his rifle when it contacted his barrel.
We both used the flat wire version. Our reason for use was much longer spring life before a noticeable change. I've read upward of 100K rounds (I'll never see that in one rifle). I use the Tubbs CS hammer spring for the same reason. ETA - Flawless function for both of us using uncut springs. |

my S&W M&P has one with a Spikes T-2 buffer. it runs everthing including Wolf just fine. I have a frankenrifle running this combo. It has a 14.5" Bushmaster barrel. I'm not sure of the port size, but it won't cycle Wolf. I have the flatwire version and I did not cut any coils. |

I have never been on a squad that had made it 100% through a stage without seeing at least one rifle malfunction. |

With Tubb's springs are folks running std buffers, H1, H2, etc.? Delays unlocking which has benefits especially for reloaders. Insanely long service life. More consistent over time than the std spring. More heat resistant, although this is probably not really a factor for this spring usage. |

I rarely see rifle malfunctions with the group I shoot with - malfunctions that are seen are usually mag related. Yea, if you run your gas borderline enough to cycle and run inconsistent ammo you will definitely see malfunctions. |

I have never had ANY rifle malfunction in any match where I was using my ammo. However, I travel and shoot the major matches all over the country, and I have seen plenty of malfs. On a regular basis. Tuned 3gun AR's are just that - finely tuned. If they get a little too dirty, a little too hot, a little sand/dust, a little dry, they just seem to stop running 100%. |

Quoted: I have two of them up and running currently, and am about to order the third. I have found them to be a very worthwhile addition to both a Colt Hbar Elite 6724, and my SBR 11.5 build. Two extremes in performance and application... works well for me. And I ordered another one today for the last of my lowers... they just make the rifles run better. |
