Which buffer/spring would you suggest.

**Derek33** · 10-22-19, 18:34

I built an upper with a 13.7” Rainier Arms Rock Creek .223 Wylde Barrel. Carbine gas system and .750 gas block seat.

What buffer/ spring would you suggest to mitigate some of the recoil?

I know ammo often plays a role in this decision. I don’t have a “go to” or preference. Usually just 55 or 62 grain I suppose.

Thank you!

A5. If you already have a carbine buffer tube on it then an H buffer should be good.

I’ve had great luck with an H3 and Springco blue spring.

Really depends on the gas port.
I would start with a springco blue spring and an h2.
Might want to go with an carbine or h3 depending on gas port size and what ammo you use.

Black Rifle Tactical's "Custom Tune Gas Port" could have saved me a lot of the money I spent on springs and buffers, had they been around when I began my odyssey to fine-tune AR ejection/cycling....

Follow up question - why are the a5 buffer systems so hard to find!? Everywhere is sold out

People like them.

You can find good deals regularly at PrimaryArms.com, though the BCM kit they sell includes an A5H0 buffet.

Personally, I just got Vulcan (blemished) receiver extensions directly from VLTOR, VLTOR A5H2 buffers from OpticsPlnet.com, and rifle springs from BCM.

Everyone over at P&S say an H3 is too much for any gun. Heavy buffer inflict wear on gas rings. I’m no expert, just trusting the folks that know more than I do. Don’t kill the messenger......

I think you’re going to get alot of advice from people saying what they use with their guns, without having the same barrel as you. Additionally, the buffer and spring is a poor place to try to mitigate recoil, though it clearly has an effect, however small.

I suggest shooting it with whatever you have on hand, if you have another lower, or already have a buffer and spring. Then go from there, if you feel that it needs something different. Alternatively, you can buy an EZ Tune gas tube from BRT spec’d for whatever ammo, buffer, and spring you choose, and it’ll choke down the gas a bit. In which case, I would suggest setting it up for a regular carbine spring or Sprinco White and an H2. Or A5H0 with a regular rifle spring.

Interesting. H3 is about the same weight as A5H2, slightly heavier than Rifle.
