Will this upper fit on a standard M4 lower? (New Frontier lower)
Surfer Ron on Jun 14, 2018
BEST ANSWER: Yea it will, as long as the lower uses standard diameter take down pins unlike the colt lowers
if i install this upper on a standard lower with a rifle stock will it make it an SBR?
jrstigger on Jun 19, 2018

Looks good
The 300 Blackout upper looks good. I would have given it 4 or 5 stars, but I have not been able to fire it. The complete pistol lower you sent my FFL had a out of spec distance between the pin holes. So I was not able to mount the upper on the lower. Right now my upper is a nice looking paper weight. Quality control problem ? Sure was with the lower. Wondering if the upper has a problem. Only time will tell.

Would buy again if I needed another AR pistol.
- Reasonably accurate; puts all the holes in a 7-8" group @ 200yds using a red dot sight. Might actually be accurate if I put a real scope on it.

- Rifling is 5 groove. Does anyone know if this is 5R rifling . . . in a pistol barrel?

- BCG coating is a little rough. Not a functional problem & perhaps it's by design as a rough surface holds more lubricant than a smooth surface, but it'll catch some fuzz if you wipe it with a patch while cleaning. I'm sure it'll smooth out with use.

- Have had approximately one misfeed per mag so far (mid mag), but I've done zero tuning on it & am shooting super & sub loads developed in my carbine-length rifles. This shouldn't be hard to resolve if it's not a break-in issue.

Good upper, especially for the sale price
I ordered this upper on one of Palmetto's frequent sales. When I received it, it would not mate to any of my lowers. The front pin went in just fine, but I could not get the rear pin in. I could fit a credit card through the gap in the upper and lower. I tried on 3 different lowers with no change, a different PSA upper fit on all 3 lowers with no problem.
Very fast turnaround and customer support from PSA. Got an RMA and return shipping label in a day, sent it back and received the replacement (I think they fixed it and sent the same one back). No problems attaching to any of my lowers now.
I was able to get to the range this past weekend, having some cycling issues when shooting with a suppressor. Might look into an adjustable gas block as it cycles fine unsupressed. Overall, looks good and works mostly ok. Will update once I get an adjustable gas block.

Got mine .!!! You snooze you loose.
I just ordered mine this morning today.
My buddy has the same upper and it shoots nice, and I wanted to get in to the 300blk craze after shooting he’s, the range buy us is about 200yards and I am able to hit an 8 inch target and the target swings pretty good compared to my 16. 556 . I was looking to save money because it can get expensive and I have been comparing PA to my existing stock pile and as far as treatment or logos there pretty much the same except the price and the only argument I can make is that a civilian model AR example colt there is very little diff. The average guy is not throwing 550 rounds down range a month I do about 200.
This my third upper I ordered from PA I also got the mid-length 16 upper and I been shooting it at the 100-200 yds and I sighted it at 50yds with about 500rounds so far and I wanted to beat on this one and it hasn’t have a problem yet and I use D&H / Magpul 30rd mags , I plan to use my 60 and 100 drum this Sunday . And I am just your average guy. And also I use that upper on my colt and bushmaster lower. Thank you for reading!!!
And be safe and watch out for the unsafe!!
