Does anyone know how this pencil barrel will take rapid fire? Thinking of putting a Bionary trigger system in the one I purchased earlier this year,
gary c on Sep 10, 2018
BEST ANSWER: It’s nitride coated so there won’t be any issues from a durability standpoint. Being a pencil barrel it will heat up quicker but it will also cool down quicker than a government profile.
I know it's chambered 5.56 nato, will it cycle .223?
Blake B on May 9, 2018
BEST ANSWER: I have had no issues cycling .223 rounds, using Lake City mostly, but have also run some PRVI, and PMC.
This says bolt carrier profile full auto. Does this mean rifle will be fully automatic instead of semi auto? Don't want a fully automatic.
MBMan on May 8, 2018
BEST ANSWER: It is the fire control group in your lower that determines the possible firing modes. All they mean here is that the BCG is rated to handle full auto.
Guys i am wondering , is this a real threaded barrel so i can change out muzzle breaks/flash hiders or is this pinned/welded in place like some other ar15 uppers ive seen?

My Favorite Upper
Very impressed. It’s my first pencil barrel upper but won’t be my last. I’ve shot 400 rounds without a hiccup. I mated it with a PSA lower, CMC trigger, and Minimalist stock. Handles like a dream. Lightweight with a red dot I’ve mounted. I have much more expensive AR’s but it’s the first one I grab when I head to the range. Highly recommend.

Did my first rifle build with this as my upper with the psa Moe kit with an Anderson lower. Fit and finish was excellent! Shoots smooth and accurate! The quality is definitely top notch! My favorite carbine for sure!

Basically what I was waiting for, and wanted
After Ian and Karl's WWSD AR builds, I was really wanting to go that direction for my 2-gun build. I researched parts for months, almost bought an upper receiver, then another time the barrel, but held back due to the costs that would add up. While this upper is, indeed, heavier, it's an affordable step closer to the WWSD project. Where the WWSD upper would have cost ~$600 for the parts ($220 barrel, $200 to $300 carbon fiber handguard, etc.), this gave me a working 2-gun upper where the savings went to ammunition, gasoline and training. It was, really, the right step for me, and I'm glad something like it was offered by PSA after about a year, or more, of looking at PSA for lightweight builds.

Best value including wholesale
Customers loved the light weight and overall feel as a dealer I could teller it was made by FN which is a a great selling point. Another well done by Palmetto.

A good upper for a good price. PSA daily deals are the best.
I like the rail across the top. I didn't want fixed sites as they get in the way of optics. I also like that there hand guard isn't attached to the barrel. This can help improve accuracy. I like that there slots on the sides & bottom can be used to attach additional rails if desired. A good upper for a good price. PSA daily deals are the best.

built it for my wife
she is thrilled with the overall compactness of the rifle.
I did add a grip to the fore end for better control and to protect hands from the barrel heat.
dressed it up with a Daniel Defense furniture package
