I tried some searches but didn’t turn up anything, please direct me if the resource alsready exists.
I have an Armalite AR-10T 16" upper (carbine gas) sitting on an Armalite AR-10T lower that originally hosted an Armalite AR-10T 24" upper. The lower is set up, I assume from the factory, with a 9 3/4’ A2 buffer tube, recoil spring measuring 13 7/8" relaxed with 32 coils and the buffer is 5.4 oz at 5 1/2" long. The recoil impulse has a distinct bottoming out pulse and as I’m not very familiar with the AR-10 system I wanted to run it by the crew here to see if everything was close to a good starting point.
ETA: My question is will the buffer/spring combo described above be OK to run with a 16" carbine-gas .308 AR?
Also the bolt will move freely in the carrier with gravity as the only motivator. Is this common with the AR-10 system? The gun seems to get drier quicker than any 5.56 that I’ve run if that matters.
Thanks,
Keith
