On my last hunt I had some feed failures. Kind of dissappointing when you steady for a shot and the trigger doesn't break. The 20 inch 11 degree target crowned non threaded barrel, rifle length gas tube and Non Adjustable gas block. I kind of built for 62 and 69 grain only with a H1 buffer weight(I think 3.8 oz) , m-16 bolt, and heavier carbine length spring. The problem started when I was only shooting 55 gr. HPBT 28 gr of cfe 223. 5.56 loading and right at 3300 fps on the chrono. I am going to try a lighter buffer spring because it passes the gas ring test, perfectly clean and 3 different 10 shot new P-Mags.
Has anyone ever cut a few coils off of a carbine spring to make their action do a full cycle or for some undergassed problem. Any other fixes like a change to buffer weights?
