What is the difference between a 16" Rifle Length and a 16" Pistol Length?
Seth S on May 29, 2018
BEST ANSWER: The difference is where along the barrel the gas port is located
I already have a PSA rifle in 5.56. Can I use the BCG from that and the charging handle when I want to switch to this upper? Is there anything else I need to do?
Steve on Jul 9, 2018
BEST ANSWER: Nothing else. Uses the same mag, bcg and charging handle. Just be sure you pay attention to what ammo and upper you are using. Dont accidentally mix them up.
What buffer do you use when using a 16"barrel with a .300 Blackout? Is It determined by the placement of the gas block (pistol vs carbine length)?

I was considering putting a vertical forward grip on my build,will a MLOK type vertical grip fit and work,if not,what type of vertical grip and attachment will work?
James S on Aug 16, 2018
BEST ANSWER: Any MLOK accessories should fit on that rail. The MLOK spots where you'll be able to attach your accessories will be on the bottom and the left and right side of your rail. Should fit right into the slots and when you tighten down they have a piece that rotates and locks in place holding everything in place. YouTube has lots of videos if you curious on what looks/fits best. Hope this helps!

Great foundation for building your own!
Highly recommend this for someone building a .300BO carbine! Shoots MOA now with factory ammo, and I hope to refine that with handloads. Only issue I had with the carbine was actually with the lower kit (also PSA). Stock trigger group was gritty, so I swapped it with a 2 stage 3.5# match trigger

Great Upper
Received this on Tues,to the range this morning,everything is as good as I have ever received from PSA.Functions very well,is accurate as my 5.56 I built 3 years ago.Bore sighted at home and zeroed at 25,fired 5 rounds at 50,[pic included],then went to 100,after firing about 10 rounds at 100,then I just went to playing on steel,consistantly hitting at 100 and 200 yards,very accurate and very satisfied....Great job,PSA.....will be buying aother lower for this upper.

Great
Really great quality. Can’t beat made in the U.S.A. Haven’t had a single problem with it. I bought the NiB BCG with it and all together pretty good. Definitely would recommend for the price.

I strongly Reccomend this Upper
Great Value for the money. Fit & finish are excellant. I put a set of UTG flipup sights on it and had it zeroed at 25 yards in 6 shots

Upper Barrel Gas system ****Great*** M-LOK handguard ***** not so good****
I received the upper and was impressed with the quality however it was a little heavy. I put a set of flip up sights on it on each end of the PICRAIL. It shot well and functioned flawlessly....until...The M-LOK hand guard fell off after about 40 rounds????? I took it home and put it back together getting the clamp on the bottom very tight. The point of aim was now too low as the hand guard was now 1/8" higher on the end . I called PSA and they took it back and sent another one. I put that one together took it to the range and after 30 rounds the hand guard fell off. I called PSA they said to sent it back I sent it back with a long letter describing the problem. when I got it back they had over tightened the hand guard and it was 1/8" high on the end just like the last one. I tried to call them but could not get through today. The M-LOK handguard will be OK if you are using optical sights attached to the lower only but don't use it for your front fixed sight.

In PSA's defense their customer service is great quick turn around etc. I am going to contact them next week and see if I can swap parts around to get a A2 type front sight that attaches to the barrel and a shorter freefloat or conventional hand guard.

Excellent upper for the money
I will start off by saying I have not shot mine yet but was impressed enough with it to want to write a review. I have ordered several uppers from PSA including a 223 Wylde and I have to say their uppers are the best you can get for the money. I put them up against my Colt 6920 and they are just as accurate and function flawlessly. I have always received my orders within 5 days and you always get what is advertised. The upper looks great and is light weight. You will not be disappointed in it. I'm ready to go shoot mine. PSA is a top quality company as far as I'm concerned and have good deals.

Can't go wrong here
This is a great upper!!! I looked for days at uppers and finally decided on the PSA 300 and I'm super glad that I did great product !! And I order it on Monday and was delivered on Wen. Thanks

2" Group @ 50 yds with cheap ammo and a 20 dollar red dot
The summary says it all....

One issue I had: after 150 rounds the handguard came loose and started walking forward on the receiver nut. Easy fix hasn't happened again since I tightened the screws. This upper is a good quality upper at an attractive price.

300 BLK upper
The 300 BLK upper assembly arrived quickly and was packaged exceptionally well much better than other companies I have ordered from. After a quick cleaning I installed it and took it to the range and was not disappointed by any means. This shot great groupings at 100 yards and was extremely accurate. Great job PSA!
