I'm currently buying parts for an AR build, and I have been searching and searching, and it seems that there are so many viables for which buffer/spring to use. I am going with a 16" mid length gas system. The barrel port seat is .750. I'm using am M16 carrier. For the stock I'm using a Magpul UBR.
Another question I have is should I go ahead and upgrade the extractor/ejector springs? I'm going to be going with the Spikes NiB BCG. I'm asking because I saw a Spingco kit that had the blue spring with an extractor spring included. My guess so far is to buy an H buffer, with blue spring, and go ahead and swap out extractor spring. Seem right? |

I have a couple 16 inch mid-lengths, an ArmaLite M15 and a PSA that I recently put together. I run a Tubb flatwire spring (20%) heavy and H2 buffers in both guns. They both function perfectly and hold back bolt on last shot even with crappy, weak Tulammo. I also run 5 coil HD extractor springs in them both also. I believe the HD extractor spring is an upgrade for any AR. The spring/buffer combo is something that you will really have to test to make sure your gun runs reliably. I believe your gun will probably run fine with the blue spring and H buffer. A standard carbine buffer and standard carbine spring can be had for about $15 though, and is a good place to start your testing. They can always be used for spares if you go with heavier spring and buffer later.
BTW, the gas port is not.750, thats 3/4 inch, the barrel diameter where the port is, this is listed so you can get the correct size gas block. |

Just my opinion, but I wouldn't go upgrading the springs unless you're experiencing a problem or you just have money to burn. I noticed it was a cheap part, so I wasn't sure if it's one of those things that might as well be upgraded while building it just so I don't have to worry about it in the future. Added bonus if it will make it perform "better" somehow. |

Sprinco makes good quality springs. I have some spare extractor springs from them in my spares kit. I don't install them unless a problem shows up though. I would start with an H buffer and standard weight carbine spring. I like the enhanced springs from Damage Industries because they often go on sale for $6 each and they have extended life of the sprinco springs without the extra cost. |

I guess it wouldn't hurt to have the backups. The gas port on the one I'm looking at is. 068 |

start with a standard carbine buffer and spring, if that isn't heavy enough than move to an "h" buffer, if that is still not enough move up again to a heavier buffer.
i am willing to bet it will run on a standard buffer, either way start there first. the idea is to make it run on the "proper mil spec" parts first, from there you can tune one part at a time. it makes diagnostics easier if something does go wrong. |
