Thinking of trying Vltor A5.......what spring

[user]

Hey team, question please. Thinking of trying Vltor A5 on a 14.5 mid. What spring is recommended. The kits I see on websites come with a stock rifle spring. But in researching some suggest sprinco green. Can you suggest a preferred spring or just use the one that comes with buffer tube kit.

The factory spring is a good spring, but the green springco is preferred.

I have used every quality rifle spring (Colt, BCM, Brownells SS, Brownells CS, Tubbs flat wire, Springco Green, Wolff reduced power, & Wolff std power.) And the factory copper washed Vltor A5 spring provided the smoothest recoil impulse.

It's literally one of the only situations where the factory spring is best.

Because it is a rifle spring, it will have an inherently longer life than carbine springs.

I've got two Vltor A5 springs that have over 4000 rounds on them and their length is identical to a factory new Vltor spring.

EDIT: My wife uses my old upper, a BCM 14.5" middy, and she uses the std Vltor copper washed spring with an A5H4 buffer. It's the apex setup for that gas system when not using a suppressor.

I prefer and use the Sprinco green spring. All of my lowers use them.

Thanks!

It's best to try different buffers until you find the right one that works the best in your set up.
The H2 (standard) seems to work the best for most. I use an H4 in my 12.5" M16 that is suppressed 99% of the time. I use an H1 in one of my RECCE type rifles.
I try to use the lightest buffer that will lock back on the last round of the weakest ammo I shoot.
It's kind of pricey to have a bunch of A5 buffers laying around but it does make a difference when you can "tune" your rifle.

To add to what Cory said..its not just what buffer is used. Barrel length, gas system length & port size, suppressed or not, muzzle device type, buffer spring rates/lengths, ammo differences, differing bolt carrier designs and other factors ALL put together play a huge factor in two things: the rifle's felt recoil and more importantly its reliability. It takes a lot of time to figure what works best or better put to discover that sweet spot of soft shooter PLUS reliably running on soft ammo like PMC Bronze. Whatever my rifles have to achieve that goal you can bet one thing will always be on them and that's the A5 system. Can't go wrong with it.

DD V7. 16in middie. A5H3 with Sprinco green. No failure to do anything. 100% reliability.
