Another dead horse, AR tuning.

[VargmatII]

I know, its been talked to death. But I am still curious.

I have a AR build with a lot of Mk12 flavour, with 18" barrel, rifle lenght gas and an AEM5 suppressor.
So far I have used a standard carbin spring and a H2 buffer.

But last week I got myself a Schmeisser multi wire buffer spring, which is a bit like the Geissele mg42 but with 2 strands of wire and compatible with regular mil-spec type buffers. The multi wire spring is a bit stiffer than the carbin spring. Some say that a stiffer spring with a light buffer is better for function. Others seems to prefer to add weight with a heavier than normal buffer. I did some testing the other day at the range.

I tried the multi wire wring with a carbin buffer, recoil was light but also snappy, at least that is how I would describe it. Ejection pattern was at 14-14:30.

Then I switched over to the H2 buffer and multi wire spring, a bit more recoil was felt but it also felt more controlled, more of a push. Ejection pattern was at 15:00.

What would you run?
I have thought about getting a H3 buffer but I am not sure it is worth the money.
I am not switching to an adjustable gas block.
