Picked one up yesterday.
I like the phosphate finish on the barrel and apparently DelTon says they are parked under the FSB, something that I've never concerned myself with. F-marked FSB that is as straight as an arrow, no cant detected. BCG has nice staking and the gas key and extractor ARE NOT MIM (like the Anderson BCG that came with the uppers PA had on sale recently) which is nice. Cerro forge marked upper with white T numbers. Buffer is H1 marked.
About sixty flawless rounds all ejecting at 3:00, not that a little forward or rearward would matter to me. I added a cheap carry handle sight and it was dead on from the start. Excellent accuracy as far as I'm concerned nut I was only at 25 yards just getting some trigger time.
No CL barrel and skinny handguards which is understandable given the price point... I'm fine with that. I already slapped on a set of fat M4 handguards I had in the parts box.
All in all for just $300 out the door I think the quality of the kit is pretty damn good... I plan on buying another next pay day to use up a lower that's just collecting dust.
