Complete buffer system - BCM vs Sionics vs Aero Precision

[Iraqgunz]

In case I missed it, I don't see where he discussed the Vltor A5. In fact in the comments section someone asked about a buffer recommendation and he said A5. But, in any case feel free to search through M4C where the A5 has been discussed numerous times in depth. You don't need to experiment because many of us have done the homework already.

Here’s the Bartocci content I referenced earlier. Wanted to check myself.

Just posted that in regards to regular carbine length buffer systems and the correlation between barrel weight and buffer weight; I mentioned it earlier and wanted to provide the reference for anyone curious.

I just realized you were taking about the video. I brought up the A5 as an option, spoke to some benefits I’ve experienced and that I’ve never chosen an A5 buffer and spring based on barrel weight or profile.
I’ll have to watch the video I guess because I still don’t get that.

ETA: updated post after I figured out you were talking about the dude in the video and not this specific thread.

Speaking about Chris' video on buffer weight in correlation with barrel weight.... When i heard him deacribe it the first time it made me go hmmm. He claims Colt uses an H in the M4 but switched to the H2 with the M4A1 SOCOM barrel strictly to lessen bolt bounce due to heavier barrel harmonics.

Interestingly I've never heard anybody else bring it up until now. After thinking about it for a bit, given a gas system that is not out of spec, it would maje sense at least to me.

Yes, I heard that as well. But it should be noted that the gas port size on both barrels is the same. Just like the barrel on a 14.5" and 16" per Colt use the same gas port. It was stated that the engineers at Colt did not feel that the additional barrel length warranted messing with the gas.

Honest question:
Do we throw this idea out when we move to things like mid lengths with different gas ports?

What do you mean? What idea? Buffer weight and spring selection?

Sorry, wasn’t clear. I mean the barrel weight/buffer link. If I’m reading correctly, it seemed like IG may have suggested that the M4 buffer solutions may have been due to not changing port size.
I may be misunderstanding, hence the follow up.

JediGuy - just do a forum search as IG suggested and you will find many posts on this subject.

I bought an Aero buffer tube (receiver extension) a few years ago and it arrived with a very roughly machined interior (exterior was well finished). I send a clear picture to their customer service, who called me to explain it was fine and it would "wear in".

I bought one each BCM carbine and A5 RE and each was smoothly finished inside and out.

Does it really matter how poorly the interior is finished? I don't know, but I do know I won't be purchasing any more Aero receiver extensions.
