Carbine Buffers in high end AR's

[BufordTJustice]

^^^This is what I have in the majority of my guns and has been my standard go to since IG (may he Rest In Peace) turned me onto it years ago. It has been a proven runner in my 12.5C, 14.5C, 14.5M, 16C, 16M, 18R & 20R guns, I see no reason to change.

As to the OP, I’ve always thought carbine buffers belong on the bottom of the ocean, if your shit won’t run with an H buffer something is ****ed up.

Yep. I got it from Will (IraqGunz) as well. RIP, Will.

I remember him also, didn't suffer any of the bullshit dealt by some on a constant basis and rarely pulled a punch. Was a large reason behind why I joined this site vs. the animal farm that will go unmentioned.

He was actually a bit intimidating! Learned a lot reading his posts and its probably why I actually have a few of those springs in my stock.

Just to throw another into the mix the JP Tuned & Polished rifle spring is noticeably smoother than a Colt spring just cycling by hand.

I switched my Sprinco Greens for JP springs. Definitely smoother.

Green by a lot, though Alan at Sprinco has confirmed they both fit and work.

SOLGW ships a green spring in every complete gun and lower they make (and A5H2 buffer). That is basically the best standard setup that I know of; largest breadth of function and also runs really well. The only carbine based setup that I've felt could challenge it for feel is the Geissele Super 42 carbine setup...but only in some guns.

Sprinco Green + A5H2 is a well proven, and good, 'recipe' at this point.

Have also had good luck with Colt (from Specialized Armament) and BCM 17-4 rifle springs. They tuck in between the Sprinco Green and the std Vltor springs in terms of strength.

I have a G barrel in my 11.5 running suppressed. It started life as a blem BCM lower so I left the carbine buffer tube set up in it. I have the G42 with H3 headed to me this week. Will be my only gun without an A5 set up and I am curious as to how it performs. Worst case scenario It goes in the spare parts bin and I switch it over to the aforementioned A5H2 SC Green set up. Wondering under what conditions you have seen the G42 set up not work well?

But even those prove my point. The Tubbs AR10 has 25% more in-battery spring pressure than a Sprinco Red and 10% less out-of-battery pressure.

The also supports my assessment of OOB pressure being between a White, Hot White, and a Blue.

Well... yes, that was why I was posting those numbers, to give further support to your claims via hard measurements, even if Tubbs only had an n = 1 for each spring.

I realized that afterwards. Thanks man.

Just had twins. Very little sleep.

I've seen the GA Super42 work best in short carbine setups. Marginal in 13.7" middies, 16" middies, 18" rifle gas, etc.

1. Good to see you posting again

2. Congrats. Twins are great, moreso as they hit the one year mark.

Ahh good to know. Should work well on my 11.5 then. And congrats on the twins! We have a few sets in our family as well. It will get easier in another 14 - 18 years

Thanks!

The amount of sleep I am *not* getting feels like a stakeout in my old unit. Lol.
