| I just got my rifle together. Its a BCM 16" mid length with standard buffer. I also installed a Sprinco chrome silicone green spring and that is what I am curious about. Should I expect it to cycle fine? Anyone run one of these? |

Quoted:
Yeah I installed a Sprinco aftermarket buffer tube spring. Someone on the internet told me it was a good idea. What was I to do? Springs are the last resort. It'll run fine with stock springs and buffer. If you want to tweak things, start with an "H" buffer. You're probably fine the way it is, but it IS fun to mess with shit, I know, but springs usually are unnecessary. Start with the buffer, if anything. |

Quoted:
Yeah its not like I really thought I had to have it. I have the stock one also. Someone said the Sprinco buffer spring can help with reliability. I guess I could take it to the ranage and see if it cycles ok. Bring the stock one as backup. There ya go... You've a back-up if needed. Try the stock spring too, you'll see it runs fine. Nothing wrong with having extra shit at your disposal if needed. Add an "H" buffer to your spare parts mix too. Tweaking shit is fine, but stock is usually just fine. |

I guess I could take it to the ranage and see if it cycles ok. Bring the stock one as backup. Was this an issue to begin with? I did the exact same thing a month ago with a Wolff Extra Power spring. My carbine ran fine with all types of ammo, but I blindly purchased a stronger buffer spring because I wanted a softer shooting rifle. Well, I tried it out at the range, and it did shoot softer, but the bolt would no longer hold open after the last round in a magazine. Personally, I'd rather have a bolt that locks back for a new magazine over a softer shooting carbine, so I returned the spring and went back to stock. I may look into getting a heavier buffer, but frankly the rifle runs 100% in the stock configuration so I am hesitant to spend money to fix something that isn't really a problem in my eyes. |
| If the spring gives me any trouble at all and the rifle does not function exactly how it is supposed to the fancy spring is coming out as fast as I can change it. Reliability is key. Right now the only rounds I have are the softer .223 so if it is going to give me trouble it should with these I would think. |

Is it a myth that if you shoot the heavy grain ammunition, you could have some problems if you have a carbine buffer therfoe a mil-spec would be better?  I never had any problems shooting 223rem ammo or 5.56mm ammo from 77gr to 45gr carbine buffer / M4 H buffer /M4 9mm buffer /M4 |

No. I was thinking with the Sprinco spring that the hotter 5.56 will be more likely to function fine. Enough force to push the bcg back and be able to chamber another round without trouble. If there is to be a problem I would guess it would show up with lighter .223? Thats what I was trying to say at least. I am not suggesting that there really is much of a problem at all. I am sure the stock spring that came with my BCM buffer tube kit will work just fine. I just have this fancy spring and want to see if it works also just fine with all ammo I can feed it. |
| Yeah I actually did "need" my new ar rifle. I had been without one for shamefully over year since I traded my Stag 16" for a 2001 CR250. I kinda got busy putting money into the bike and into a few other guns like a Glock 10mm and a Browning HP. I do feel better with an ar. |

Why did you install an aftermarket buffer spring? Cause the cheap ass stock spring sucks, and a quality chrome silicon spring will probably last the life of the rifle? I run the extra power red spring with an H3 buffer in my BCM 14.5 mid, eats anything I throw at it. |

What buffer would anyone suggest running? I have the Spikes m16 bcg and the Sprinco spring but I went with a regular buffer. I was not sure what to get. |

You both assume that all ARs are made exactly the same and thus have the same gas pressures and cyclic action. This couldn't be farther from the truth. But hey, what do I know? If you're going to flip your opinion that quickly, then I'll just slowly step backward and leave this discussion area. |
| I am not really flipping my opinion I just do not know. I take all advise and filter it like anyone else. If I got on here and 20 people in a row told me to ditch the Sprinco or do something else I would take it into consideration. I have a 16" mid length BCM upper with a Spikes NIB coated BCG. Sprinco buffer spring is the only slightly strange thing I think. |

Obviously the first consideration is having a rifle that functions as intended. If you have a rifle that does this I see no problem playing with it a bit. At this point we're simply talking about swapping parts and it's easy to go back should you not like the result. I've done this with a number of rifles and ended up with rifles that not only function 100% but are nearly as tame as a .22 LR. I have a TacSol .22 LR AR and have something to compare these rifles with when I make a statement like this. A 5.56/.223 isn't going to bruise anyone's shoulder but I do have an artificial shoulder and appreciate a gun that has as little recoil as possible. I haven't used the springs mentioned but I have used Tubb's Flat Silicone springs and had very good success. Along with the springs I've run Spikes ST-T2 buffers and very much like the result. Having said all of this, GC7 hit the nail on the head. You will get different results from rifle to rifle. I've had rifles that were as close to identical as I could make them. One handled the mods exactly as I would have hoped it might. The other began to short stroke once the buffer and spring were installed. After a conversation with Superior Shooting's (Tubb's) techs, I was instructed to remove 3 coils from the Flat Silicone spring. I did as was instructed and this rifle then worked flawlessly. Clipping the spring did not increase the recoil as far as I could perceive. Bottom line here is to first make sure your rifle works and then have fun with it. Shooting is fun but so is trying something new. Good luck. |
| I think I pretty much got the answer which is to take the thing out and run it and see how it goes. There is not really that much I can change. Buffer spring and buffer. I also have the Sprinco extractor spring I have not decided on yet. I may put that in also. Its supposed to last longer than stock but I do not know if it will have any effect on the rifle cycling ok. |

Quoted: So many people here have had such great success with the stock buffer spring and buffer, why change it? There are legitimate reasons and though they may not apply to the masses they still exist. Quoted: ...A 5.56/.223 isn't going to bruise anyone's shoulder but I do have an artificial shoulder and appreciate a rifle that has as little recoil as possible... Though most don't have aftermarket parts installed in their bodies there are a lot of shooters running around with shoulders that give them problems. They might just appreciate a modification of this nature. I know this next statement is blasphemous but I personally don't care for the traditional SPROING that the factory spring makes. A flat spring coupled with an ST-T2 virtually eliminates this noise. For me it's a win/win modification. |
