Hi Guys.

Thank you for all of the help. I haven't updated because I'm halfway through a 13 day work week and I've been completely worthless. Today I had to get up and be a productive human being, so I was able to catch up on this. I put together some pros and cons of this upper:

Pros
Affordable
T marked
M4 feedramps
Decent extractor internals

Cons
Possibly incorrect front site base
CAR handguards
Bolt assy only batch inspected
Per Eric's evaluation, dry film lube flaking off inside

Draw
4140 barrel, my AR won't be seeing any full auto abuse
1-9 twist, now a big deal to me, 77grain loads get pricy, and we qualify with 55 grain Winshester.

Thanks again for all of the help. Before posting this, I saw that the owner sold it for $410 w/o the carry handle. Unless I can work more overtime or find an empty credit card for an LMT, I may wait 'till the National Matches and try to find something good there.
