I believe IG said this once "even though it's an FN barrel it's made to PSA specs" ie-improperly sized gas port.
I can promise you PSA doesn't go through as extensive testing that the BCM is. To say that PSA MPI BCG=(or even close)BCM BCG is a bit of an exaggeration.
I was exaggerating the 3x, but I'd rather spend 3x what a PSA is for a BCM anything.
Case and point.

I'm not trying to be ugly, I'm really just trying to keep ppl away from PSA. Your money will be better spent with BCM or any of the other well know quality manufacturers.

Correct me if I'm wrong, Is there an industry standard for a mid length gas port?
I have a PSA 14.7 chf w/smith vortex pinned & welded.it wasn't under gassed or over gassed & I couldn't tell the difference in accuracy between it, my DD m4v7 or my BCM middy! I don't understand the hate for PSA. Yes FN makes their chf barrels, it's not like the barrel steel is any different than any other company FN makes barrels for.

[QUOTE=rocket 442;1963252]No, there's not.
Check out this thread.
https://www.m4carbine.net/showthread...-gas-port-size
Makers know what size gas ports work and they understand the trade off. They can make the ports a little on the large size so the average shooter can happily run even the weak stuff reliably with a few grumbles from the serious AR guys, or they can properly size their gas ports to satisfy the serious AR guys and listen to the grumbles from the average shooter. S&W went the latter route with the M&P-10 and they are catching flak because "a $1500 rifle should run reliably on ALL ammo".
Certainly FN will make barrels to the retailer's spec but that doesn't mean the spec will be automatically wrong. It does means the buyer needs to be aware of the facts before laying down their hard-earned cash. I have a middy carbine with a stainless steel barrel built from a PSA kit and except for a hiccup with the feed ramps (which PSA took care of in a professional, timely fashion) it's been as reliable as a rock. There is no evidence of it being over-gassed as it will start short stroking using heavier buffers with full powered 5.56 and needs a light buffer to run steel cased ammo reliably.
Your link proves my point- that upper is good stuff- except that the bolt may not be HPT/MPI. (Myself, if I'm getting a bolt from a trusted source, I'd rather it not be HP tested.) When buying from PSA, you have to know what to look for to avoid unpleasant surprises.
That doesn't mean I think someone should get PSA instead of BCM. But you can put together a solid, reliable rifle from the PSA parts catalog as long as you are educated

@OP: if your muzzle device must be pinned + welded anyways, definitely go with the 14.5 barrel w/ a pinned + welded 1.5" compensator/flash hider. I am completely unfamiliar w the nuances of the laws of commie states, but I do think you should thoroughly examine everything before you order. What's this about no bayonet lug? wtf? You can only have comps, not flash hiders??? Since you are going to be pinning the muzzle device anyways, that lends even more weight to the low profile gas block perspective (IMO). There are numerous solid flip up BUIS.
....BCM > PSA....
Yes NJ law states the in order to have an AR style rifle your stock must be fixed or pinned (no collapsable), you can not be able to attach as bayonet, and no flash hiders or threaded barrels able to fit a flash hider. Not to mention you can not have more than a 15 round magazine.
Pretty funny to see people badmouthing a brand they probably have zero personal experience with. One of my rifles is *almost* a complete PSA build. I've put about 6400 rounds of all kinds of variations of weight/load and from match quality to trash downrange with it thus far and have had, count them, ZERO malfunctions of any kind. Bad mouth PSA all you want, but in my own personal experience with BOTH brands, all other things being equal, a PSA rifle built with the right parts will run just as well, for just as long as a BCM. For significantly less cheese.
The rifle is only as good as the individual operating it.
As far as a FIRST rifle goes? Between BCM and PSA? No brainer. PSA. I made some mistakes when assembling my first rifle. If I had made those mistakes on a BCM, I would have been very, very upset.
When your 16 year old kid needs his/her first vehicle, would you suggest a 2015 Supercharged Dodge Charger or a 2001 Buick LeSabre? Exactly.
What does the Buick teach you? It teaches you (hopefully) how to properly care for and maintain your vehicle as well as how to drive it in a responsible manner without the added risk of destroying a more expensive machine. Once you learn to properly and consistently care for the Buick, and to operate it with a high level of ability, then you can think about upgrading to the much cooler though no more useful Charger without the risk of making a mess of an expensive vehicle through foolish mistakes or plain neglect.
Make no mistake, no matter what AR variant you buy, if you do not maintain it properly, it will fail on you. Learn the ropes on a Buick first, then think about trading up.
Or, just throw money at it. And if you've got some extra, you can throw it my way, too, if you're just looking for directions in which to throw money.

I found this site and a few others when I gained interest in AR's. I chose to learn from this site because the info I read up on was (to my knowledge) honest for one and straight to the point no B.S. I unfortunately gained interest in this platform at the most unfortunate time during last years panic. I purchased the first lower I could find at the time and hung on to it until things calmed down. I hoped. In the meantime I searched through dozens of threads here at m4c and read up as much as I could. Prices in the meantime kept falling and long story short I decided on a PSA upper. I built a complete rifle with iron sites for a little under $700. I have since added a few things from knowledge I've gained from this site. I've spent money where I needed to and saved money where I could from info off these threads and I thank all of you guys. Approximately 2k flawless rounds in less than 6 months and not a hiccup. Now I am not an "operator" or anything like that and in the future I would love to take as many classes as I can with this rifle to truly see what it's got. Maybe in a class it will fail or it may not, but I'll know why it failed and what I can do to improve or move onto something else.
I could have bought a turn key rifle like a bcm, noveske, dd etc... I just didn't want to be that guy with the expensive safe queen that doesn't know shit about it.
I guess what I'm trying to say is if you use the info on this site you can build something you can be proud of.
