So you’re saying that any ammo in an Semi auto platform is at risk of a slam fire if it’s not utilizing CCI primers?

Yeah I’m hopeful that may be it. I pulled it apart and the extractor and ejector seem to be 100%. I lubed the hell out of it and I’ll give her another go.

What do you mean by ammunition like that? Because of the bullet design? I built this gun primarily to be a hunting rifle, so ammunition with those sort of tips will be used. I was not aware this was an issue in this platform, only heard of that in tube feed lever guns.

Greetings gents. First AR308 build, 5th AR platform build overall. Gun specs: Faxon 20" pencil barrel Superlative Arms adjustable gas block Springco Orange extra power carbine buffer spring KAK Industries 5.3oz buffer Toolcraft nickel boron BCG Magpul Pmags Took the thing out for the first time today with intentions of tuning the gas block. Started at 4.5 turns out (normal operation, no blow-by or restriction). Shooting Remington Core-lokt 180gr. I was single loading the mag to make sure the bolt was locking back while I tuned the block. At first, when it did eject, they were coming out at 1 O'clock. Through adding more blow-by I eventually got them to eject at 3 O'clock. The thing is, about every third round it would not eject the case, it would be lying on the mag, sometimes turned 180 degrees. It did this if it was at full power or with blow-by introduced, so I do not believe this to be a gas issue. Also, the bolt locked back every single time as it should. I feel somewhat foolish as I did not clean or lube anything before heading out, with the exception of a quick wipe down. These are all brand new parts. I'm about to tear the bolt down and see if I can find anything, but I'd appreciate a shove in the right direction and any glaring issues with my setup. I feel like I did a great deal of reserch before selecting components so this is pretty disappointing. None of the other AR's I've put together have ever had an issue.
