I'm making a "small parts order and was thinking of trying out an H-buffer in my midlength. Brownell's lists quite a few, which one to get. (except Spikes) You could just buy a good known quality H3 buffer and if you have a standard carbine buffer, just use one tungsten weight to try a H weight buffer, two tungsten weights for H2 and all the three tungsten weight for H3. Try all the different weights on all your ammo and pick the one you like that works the best. I just use H buffer on my 16" midlength barrel, I have Colt, LMT and BCM brands, I mainly use surplus military ammo sometimes commercial .223 cheaper bulk stuff. |
| i'm gonna be different,, i'm not sure why the avoidance of the spike's buffer. i have tried/changed them in an LMT and a DD carbine. with 3 of us shooting them, we all agreed the spike's ST-T2 shot smoother. is there a thread i missed, informing everybody they should not use these?????? a blue ''springco'' spring, and a spike's ST-T2 buffer works for me,,, regardless of what the ''experts'' have decided. help me out here guys,, if i am on the wrong track..... ''don't fix nothing that ain't broke''.....AND ... doesn't DD use these buffers, from the factory????? |

''don't fix nothing that ain't broke''.....AND ... doesn't DD use these buffers, from the factory????? You've got it backwards. The Spike's *is* the "don't fix nothing that ain't broke" option. Nary a thing was ever wrong with standard, reciprocating weight buffers. I guess if you're busy worrying about how the rifle sounds when you fire it... Alpha-Romeo3 has the right idea with getting a carbine buffer and H3, and "mix and matching your own buffer. Particularly if your weapon already came with a standard carbine buffer, you can build yourself an "H" (1 tungsten - 2 steel) and an H2 (2 tungsten - 1 steel) buffer for the price of one H3. For that matter the Springco spring is an "if it aint broke" modification too. Neither will probably ever cause problems that most users installing them will see, but heavier springs change the timing of the weapon. Like evolution - most mutations are harmful. Only a small fraction are beneficial. Mike Pannone, who is one of the users that first advocated for the use of Springco Springs and heavier buffers (The M4 Fouling Myth) changed out the factory parts, and ended up slowing his weapon down and short stroking. When he re-installed the factory parts, his M4 ran almost twice as long. ~Augee |
| This is a great topic, because I was just researching the Spike's buffer myself since it comes in their complete lower that I was looking to buy locally for a good price. I was planning to run it with a BCM middy 14.5" upper. From research most agree that the "H" buffer is about right for this setup, but I was curious how the T2 would work. I'm still trying to decide whether to just assemble a lower, or buy this complete one, but it seems like the complete lower will save me a decent amount of money toward my ammo fund. |

Well, I've never really had an issue with a carbine buffer except sometimes when it's dirty I have to use the forward assist. I recently changed to an A1 stock with rifle buffer and have had a couple of issues that I don't know if they were mag related or a combination. I'm changing back to a tele stock. If I change the buffer should I change the spring too? Do springs go bad? My carbine spring has maybe 6k rounds on it.

I ran a 9mm buffer in a 16" midlength for a while but decided I didn't want to risk the rifle not operating correctly with under powered ammo, just in case. I'm sticking with standard H buffers for carbines and middies from now on.
I run the 9mm RRA buffers and works great. I think they are the heaviest ones for 25 bucks. Anyone else have input using the 9mm RRA? |

At 6K I wouldn't really worry about it. What I would worry about, however, is that the A1 (rifle length) stock and carbine stock use different length springs - you'd have to replace them. Did you use the same spring last time you swapped? Maybe that might be the source of the problems you were having with that configuration. ~Augee |

Anyone else have input using the 9mm RRA? http://www.rainierarms.com/?page=shop/detail&product_id=119 Using a 9MM buffer is just inviting bolt bounce. The 9MM buffer is designed for the recoil of a 9MM blowback operation - no rotating bolt or locking lugs or cam pin. The reason for the recipocating weights is much like a deadblow hammer - the buffer in DI system needs to "slam" the bolt home, and then keep it locked in there, because of the tendency of the bolt to "bounce" against the barrel extension. It's not as much of a problem in semi-auto as it is in auto, but it's still not something I would want or accept just for a little bit more buffer weight. The 9MM buffer doesn't have enough reciprocating mass to hold the bolt shut in DI operation reliably. If you want a heavier buffer, go with an H3. Leave the 9MM buffers in 9MM systems. ~Augee |
