I have an Ar-15 that is short stroking 1 to 2 times per magazine with the occasional failure to look open on an empty magazine.
With factory ammo I had not noticed any problems. I tried making some reloads and am currently at the high end of the powder range and still having issues. (Note these reloads worked well in my other rifles).
I checked the easiest thing first, the gas rings look fine. I took off the hand guards and see quite bit of what looks like carbon, coming from the gas block, on the barrel. I pulled apart one of the other rifles that was working and there is absolutely no carbon on the barrel coming from the gas block.
This rifles is a bcm upper. 14.5’ barrel,Mid length gas system, with an A2 front site base gas block, and a spikes tactical T1 buffer(weight is 2.99 ounces).
Thoughts on things to check? Should I replace that gas block? The rifles had probably somewhere between 500-1000 rounds through it.
