Will kit 0086 bcg fit and work with the 516444536 upper. I ordered the upper and my Ruger 556 bcg will not completely drop down into your upper without jamming about 1/4 " short of dropping all the way in.
The Ruger is mil spec according to the factory. Does this have to do with head spacing?

Do you have the BCG and charging handle?

Will this upper be compatible with the PSA AR-15 COMPLETE CLASSIC LOWER - NO MAGAZINE - 7244?
Ethan T on Jul 20, 2019
BEST ANSWER: Yes. It will attach to the classic lower.. most ar 15s 556/223 if not all ar15s are interchangeable.. i can put my windham upper onto my psa lower or my psa upper on my anderson lower. You should NOT have any problems. Happy buying.
Any chance you can trade out flash hider for muzzle brake, so it will be legal in crazy Cali?
Ldb777 on Jul 19, 2018
BEST ANSWER: before you install the upper to the lower, swap out the flash hider for a compensator or muzzle break then install after that. I recommend having a muzzle device ordered or on hand already before the upper arrives.
Will this work with .300blk ?
Ppepin24 on Jul 25, 2019

This upper will NOT work with 300AAC. It is chambered for 5.56.

What kind rail system is used on the PSA Uppers?
George J. C on Jan 2, 2019
BEST ANSWER: The four uppers I’ve gotten all had M-Lock PSA rails, and another was just the plastic handgurds that I replaced with a Knights Armament tail. The M-Lock rails are actually really nice quality and the finish is flawless
Can you attach mag pull m lock hand guards to the upper and fore grips?
Aj V on Jul 29, 2019
BEST ANSWER: yes I actually just attached a magpul foregrip to my rifle this past weekend
Is it preassembled?
Dakota on Jul 19, 2019
BEST ANSWER: All you need to install is the BCG and charging handle.
Does it use a standard barrel nut for the handguard?
Steven on Aug 2, 2019
BEST ANSWER: no, as with most free float designs... the barrel nut is proprietary to these handguards.
Will this fit a sig M400?
Jimmy on Jul 23, 2019

Wife likes it
After firing some of my other builds, my wife wanted to have a rifle to call her own. Looking through the uppers here on PSA, there were a few that stood out as being lightweight and comparable to what I already owned.
The feel in the hand of this rail is much better than what was offered by other companies of yesteryear, and the lightening holes in the rail gave the rifle a more balanced and light feel.
Though not the lightest one in the safe, this package comes in at a little over 6 pounds with an optic. Not bad for the money spent!
I'd recommend this to anyone who is looking to build a quality, budget-friendly rifle that will last a very long time.
I might be picking up another one of these for myself.

Excellent Value
Recently purchased this upper and after running nearly 600 rounds through it I am impressed. It ate a mixture of Federal XM193, American Eagle .223 and Barnaul .223 (laq + sealed) without a single issue. It's a really good value and the fit and finish was just as good as any other major brand.

Bravo PSA.

Affordable and well made
Overall im happy with this purchase... Paired with an Andersen lower and palmetto BCG and lower parts kit she works like a charm.Shipping was kind of slow and there is a little "slop" between the upper and the lower but not enough for me to complain or do anything about. So far ive put about 200 rounds through it and everything has functioned flawless.
Overall happy with the purchase

Great upper, will likely order a second when in stock
I have to say this upper paired with their lower is super light. I fully expected that I would need some gloves with their handguard due to the barrel heating up. It wasn't a problem. Very nice looking upper and was pleasantly surprised to find that it grouped just below 1 moa with 55 gr LAX ammo. I look it so much I will probably order another.

Would buy again and also recommend
I’m very happy with the quality of the complete upper. To me it was the best deal I could find especially if you’re on a budget. Upper lined up great on a S&W lower. Haven’t taken it to range yet but I don’t think there will be any problems.
