Hi is the barrel chrome-lined on this upper?
Z H on Apr 24, 2018
BEST ANSWER: No,this is not a chrome lined barrel but that takes nothing away from this very good product.
can this upper be had with an A-2 upper receiver?

Sir is this considered a pistol upper?
Chas1 on Apr 25, 2018
BEST ANSWER: The barrel is 11.5 inches long, so it will have to be matched with either a pistol lower, or a correctly registered SBR lower.
Is this a a2 or Heavy barrel?
Bway36 on Jun 8, 2018
BEST ANSWER: A2 barrel. Great upper. I have it on a pistol with a KAK shockwave brace and carry handle, and it is a phenomenal little package to keep in the truck.
How long is the hand guard if I want to drop in a different one?
S P on May 4, 2018
BEST ANSWER: Standard AR carbine length. So if you plan to buy an aftermarket hand guard make sure it says "carbine".
Are these still made? Many of the reviews are from a year ago.
Evan E on Jun 16, 2019
BEST ANSWER: Dont believe so. Seems they do a limited run every once in a blue moon. Bought mine a year ago and never see them for sale
Is this a Premium, CHF or Freedom?
Jon B on May 27, 2019
BEST ANSWER: Jon, I believe the succinct answer is "No."
This barrel is not marked "Freedom," "CHF," "CL," or "MP."
What you get is a phosphate coated barrel without chrome lining. In the product picture, the barrel looks shiny as if it were nitrided. However, in person, the barrel has a dark, matte-grey patina.
What's the overall length of this upper assembly?

Great Upper for the Money
I am thoroughly happy with this upper! I mated it to a pistol lower with an SB Tactical SOB brace and Franklin Armory BFSIII trigger. It makes for an incredibly light, compact package. My 16" ARs feel like muskets compared to this thing.
I have shot mostly steel-cased Tula 75gr. .223 without any issues. When I ran out of Tula, I fed it some Federal XM193. Again, without issue.

My advice: catch it in stock and on sale and buy without hesitation.

Favorite SBR upper
A big fan of the AR SBR platform, especially from the Vietnam, 70s, 80s and 90s. This upper helped scratch that itch. It's literally my favorite upper for one of my registered lowers. I swapped out the oval hand guard for the slim commando version and threw on a detachable carry handle w/ optic to give it that retro look. Let's just say it's the cat's meow/the bees' knees now.
More reliable than a 10.5" upper(there's a reason why the xm177 had a 11.5" barrel), while just as compact and manueverable.
I would totally buy one of these uppers again so I can put together a XM177 upper but haven't seen these available for purchase in quite some time.
Regardless, if you're in the market for an upper for a pistol or sbr build, this is definitely one to get.

Ar pistol build
Picked this up to make a pistol version of the Colt Commando with a Shockwave brace instead of a regular stock. Build came out good, system was a little over gased which is a common problem with short barrel ARs but a heavy buffer and flat wire spring fixed that. All in all everything came out great and quality for the price is outstanding.

A really great 11.5" budget pistol upper
My first budget pistol build. Used a PSA stripped lower. Really wanted a 11.5 classic upper and was going to build my own until this showed up in stock with free shipping. Had to have it! Threw on a Colt carry handle rear sight from the spare parts drawer and hit the indoor 25yd range. Only 50 rds in so far with Federal American Eagle XM193 55gr and perfect function. Very accurate. This upper is very well put together. My first PSA upper and overall I'm very satisfied with the purchase at a price that simply can't be beat for the quality. Hope to run some 64gr Gold Dot through it soon, then maybe try the 75gr meant for SBR's. Hoping the 1:8" twist will be fast enough. Would have preferred a 1:7 but this is a great upper regardless!

Good tight shooting upper.
First 3 rounds 3/4 inch at 25yds with out even touching the sights. Shot a box of Fed. Am. Eagle w/o a hiccup. Will fine tune when I get time and optics.

Good so far, slight amount of play between upper/lower
Good so far. Combined this with a Toolcraft BCG and PSA Complete MOE EPT SBA3 Lower. There is a little bit of wiggle between upper/lower (tested various lowers, loose in all). The FSB is slightly canted, which is kind of frustrating. Several hundred rounds of Wolf Gold without a problem. Have not shot suppressed, hoping this functions great when stamp arrives.

Upper = 4lb 5.7oz as configured (TC BCG, Romeo 5, PRI BUIS, MOE-SL handguard, BCM VG short, 1x MLOK QD sling attachment)

Satisfied with this upper for the price.
