Well, I finally received all the parts, and finished my 9mm carbine. Here are the specifics: Spikes Tactical Lower Hahn dedicated mag block Standard LPK with RRA 9mm hammer Magpul CTR (Mil-Spec) in Foliage Green Magpul MIAD in Foliage Green Magpul Enhanced Trigger Guard Spikes 9Q 9mm buffer Wolf Extra Power Action Spring RRA CAR flat top upper Older Aimpoint Comp M 2 ProMags 2 Cproducts mags (with old style followers) The build went pretty smoothly. I only sent one pivot pin spring and detent across the room (got on my hands and knees and found the parts. Yay!). One minor issue, apparently the enhanced trigger guard was slightly out of spec. The front of the trigger wouldn't fit fully into its recess. Some careful use of the Dremel, and the trigger guard was good to go. Went to the range today, and right off the bat, had FTE with every mag. The spent case stayed inside, right on top of the magazine, and kept the next round from chambering. Took the needle-nose pliers and gently bent the ejector inward to lightly brush against the bolt. That did the trick. Both Cproducts mags and one ProMag ran fine after that. The second ProMag wouldn't run. It was a bit loose in the mag well, and I found that if I held the lower part of the mag forward, it very slightly changed the angle at which rounds were entering the chamber, and it ran fine. I think I can make a slight mod to that mag to get it to run, but I am not pleased with ProMags. I will be buying more Cproducts mags instead. Overall, I am quite pleased with the carbine. Next step is to SBR it, and build an upper with a TROS 5 inch 3 lug barrel, and mount up a can. Should be tons of fun.
