9mm ar buffer recommendations?

[bugsy714]

Hey there I was wondering if any of you have any recommendations for a budget 9mm blowback buffer and spring combo. I am also trying to figure out what other parts to populate my lower with thank you very much for your help

My AR9 never ran right til I popped in a Q buffer. Not cheap though.

That is what I have heard as well these things can be finicky and cheap is always expensive

The guy I bought it from had a $150 hydraulic buffer in his lower I would have bought the lower as well but he sold it before I bought the upper

... budget 9mm blowback buffer and spring combo...

Standard 9mm buffer and carbine spring.

Standard 9mm buffer and carbine spring.

This is what I was planning on trying first

Here are a couple good solutions that are extended length and contain moving weights.

Very cool thanks for the recommendation with a blowback 9mm do the weights help the bolt slow down?

I use both, Frankin 9mm rifle 16" barrel with a spikes ST9 buffer / Tubbs Flatwire spring and other the AR 9mm pistol JSE upper 7 1/2" barrel using RR 9mm buffer and spikes spacer / standard carbine spring.
The rifle, I have run a standard carbine spring without issue, I switched to Tubbs spring to run slide-fire for added bolt closing pressure, added bonus it softened the recoil to
I would run a Tubbs spring on my other 9 but the flatwire spring wont fit over the RR buffer.

Both function 100% with any brand ammo many thousands of rounds thru both (115, 124 and 147 gr)

I've been running 9mm AR for few yr's I had asked JSE when I first bought my 9mm pistol upper what buffer they recommended, they claimed their uppers would function with standard carbine buffer and no spacer.
Mine did function just fine but just to avoid breaking bolt stop I chose to run 9mm buffer and spacer
With spikes buffer you don't need a spacer as it longer
