What is the difference between this upper and upper 625?
Jay K on Jun 17, 2018
BEST ANSWER: The 625 has a continuous rail for mounting optics. The other has an interrupted rail for mounting optics. It’s a matter of what look you prefer.
Is this available on left hand upper?

Mostly satisfied.
Very happy with purchase even though it had a blemish on upper receiver under charging handle. Must have slipped through the cracks. But it's okay since it's a tool.

Worth the money
I only have about 300 rnds through this gun but in that 300 rnds it hasn't had any hiccups. I wouldn't say it is the most accurate AR pistol I own but it is accurate enough, especially since most people don't buy pistols/SBR's with the intentions of shooting long distance. Good fit & finish too. Thanks

Terrific Value
I ordered this upper to pair with my PSA pistol lower. Great fit and finish. I wouldn't hesitate to recommend this upper!

Worth every penny
Finally got my 10.5 .556 upper out on the range today zeroing at 100 yards with iron sites shooting cheap ammo my cluster was about 5 inches across.. I'm thoroughly impressed love the quality.. put this upper on my radical firearms lower and it ran perfect.. I will be buy more psa in the future I'm just waiting for a good sale on a complete lower.

Solid performer.
I finally got around to shooting this on a pistol lower that I built. The gun functioned flawlessly. Ejection was consistent at 10-12 feet and a little less than 3 o'clock. The only negative I have found on this upper is that the QD swivel slot is not rotation limited.

Shoots well
Love this rifle, shooting it has several friends convinced to buy their own. Only issue I've had with this upper is it doesn't like 223 tulammo, it shoots other 223 steel cased and any 5.56 steel cased I've thrown at it. Brass cased has never caused a single malfunction in any of my psa rifles. I attribute the malfunctions with steel cased tulammo to underpowered ammo, and I'm sure I could tune the rifle to shoot it but I don't much see the point.

Ran 100%
I was skeptical about these short-barrel uppers, but I wanted to try one out on my registered SBR lower. I researched barrel lengths and talked to a few knowledgeable friends. Then when this one went on sale I picked it up. I finally took it out today, and it ran flawlessly. I like the handiness of the length. I did wear a leather glove to protect my left hand from the hot handguard. I now have some rail covers on order. I would recommend this to a friend.
