My first AR was a Bushmaster XM-15 M4A3 Patrolman's carbine that I bought in Nov 2014. I've only got 800 rounds through it, but it has been trouble free. I have changed a few things on it tho. I took off the removable carry handle, installed a red dot sight, installed Magpul FDE furniture, replaced the OEM BCG with a PSA premium BCG, installed an ALG Defense (QMS) trigger and JP Enterprises enhanced reliability spring kit, installed a BCM 4b charging handle and installed an H2 buffer.
It was $600 for the rifle, but I've got right at $1100 invested in it. Oh well, I enjoyed doing it.
Okay, I understand what you mean about the gas key, not sure what you mean about the extractor spring. Would that apply to PSA's BCG extractor spring too?BM BCG's aren't too bad, but you'll want to re-do the gas key and replace the extractor spring with the propper version for whatever setup you have

I did actually get a BCM bolt rebuild kit for the bolt that came with my PSA AR. I can't remember now if it was the extractor or the ejector pin that chipped. I started getting several FTEs per magazine. Anyway, replaced both and that fixed it.I reccomend the BCM extractor kits
