Complete buffer system - BCM vs Sionics vs Aero Precision

[MistWolf]

What weight A5 do you generally use?

A5H2 & green spring. Haven't tried other A5 buffers.

I would disregard the Vltor A5 and stick with what you know. There is no downside to the Sprinco spring and it will work just fine.

Like Robert said, A5 if you're assembling with kids in mind. A5H2 is the default weight per Vltor, for good reason. You don't need a Sprinco green for that mass; a regular rifle spring is arguably better.

I like the A5A2 and a standard rifle spring........very smoooooth

I have BCM 14.5 ELW. I switched to a BCM H3, Springco Blue and SOPMOD bolt upgrade kit. Soft shooting and utterly reliable. Notably smoother and softer than with the stock spring and buffer.

I have several Vltor A5 H2 and one A5 H3. Also BCM, V7 and Sionics. No Aero and no plans to get one.

I've read countless debates about buffer/spring combinations..... Am i the only one who typically just runs an H or H2 buffer in any mid length or carbine using just a regular USGI carbine action spring? Are the green, blue, white etc. sprinco springs that good?I've got a VLTOR A5H2 with regular rifle spring in only one gun. Never had a problem with either setup.

I personally like the Sprinco springs enough that I use them in all of my AR's. It's not just about a perceived performance but also the life or duration of the spring. I recommend blue for the standard carbines, and green for the A5 stuff.

I’m going to heed this and set aside the A5 option for now. I get the benefits, but if I want to experiment, I’ll try it out on my “nicer”guns first.

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