View Full Version : AR9

I have 2 of your AR9 Glock mag compatible lowers. One I built into a pistol with the 10.5" barrel and a blem LRBHO. I had no idea that the Anderson 3.0 buffer was too light for this application. You are out of your 9mm buffers so I ordered a 5.4 Spikes from elsewhere.

One trip to the range so far. The bolt only locked back a couple of times in 150+rds fired. Is this possibly due to the light buffer? Or does something have to be tweaked in the bolt catch? I am hoping this gets resolved easily.

Got any more LRBHO lowers in the pipeline anytime soon?

BTW neither one of my AR9's liked everything I fed them so far except the Winchester Forged.

Damn forgot I had this going. I dropped in the Spikes 5.4. It works good now. I did order some 8.2 oz buffers today from JSE for $22 each I couldn't pass on them. https://02b5f6c.netsolstores.com/guntecar9mmbuffer.aspx?utm_source=1011+Guntec%2FLo wers&utm_campaign=JSE+New+Guntec+Items+Available+And+Lo wer+Receiver+Specials&utm_medium=email
