Is the barrel 4140 or 4150?
Ben B on Nov 8, 2018
BEST ANSWER: PSA customer support told me that this has a 4150v barrel
Is this upper a good match on a Colt LE6920 ?
Fred S on Dec 26, 2018
BEST ANSWER: I don’t own a 6920 but it fits just fine on any of my milspec lowers. I’m sure the function will be just fine and I’ve never had a fit issue with any psa upper. I can’t speak on the tone of the finish or color if that matters to you.
Does this upper come with the premium full auto BCG ?
Aaron S on Dec 30, 2018
BEST ANSWER: No, it’s a very basic BCG
Does it come with the bolt and charging handle ?
Omaraudi on Dec 2, 2018
BEST ANSWER: Yes.
Is that a QD point on the rail?
Lorenzo F on Nov 12, 2018
BEST ANSWER: Yea that should be a QD point if you're talking about that spot three or so inches right of the ejection port in the picture.
As there doesn't appear to be a lower picatinny rail, what are the mount options for the underside so I could use something like a bipod?
Tim O on Dec 31, 2018
BEST ANSWER: Yes, with the instal of a rail using M-LOK. Sold separately.
Whst is the torque spec for handguard hex screws attaching it to the barrel nut?
Mike M on Dec 29, 2018
Thanks for all your answers, this is the Old Man Fred S, I'll grab one while I can. Happy New Year ?
Fred S on Dec 26, 2018
I just purchased this barrel. Which base for my scope works best, and I have to keep in a budget? I have a quick disconnect for my scope but require 4 screws. Is there a place on the barrel to accept this, or does it have to attach to rail?

Very Good Upper at an Excellent Price
This upper has been 100% reliable during my initial test firing, including with steel-cased ammunition. Accuracy has been good for an iron-sighted carbine, although I have only shot it at an indoor range where the max range is only 25 yards. Parts quality is good, and assembly is solid. This upper also looks very nice to my eyes. Overall, I have been impressed with this upper, and the price is hard to beat. I would recommend this upper to anyone considering one of this configuration.

Really looked forward to this upper.
The good:
It’s solid with a nice finish.
The bad:
Looks like some parts have been used. (Copper marks on feed ramps.)
What appears to be rust on the ejection port cover. And my biggest gripe, the poor excuse for a staked gas key.

Had it for two days. I have yet to fire it. Dry packing was expected but it’s gardly a smooth action even with generous lubrication. The bolt does not move freely by hand in the carrier as it should. Has a resistance while charging it.
Overall I believe it will function fine.
