Is this the exact same as the: FREEDOM RIFLE KIT - 507617? I couldn't spot any differences when reading the pages. Maybe I wasn't reading carefully enough?

Pretty good, handguards are kinda cheap
Pretty nice for the money. A note though ... handguards are single shield and barrel nut was barely finger tight. I had to remove gas tube and torque to spec. I’m sure I could’ve returned it to have this fixed, but easy enough for me to do in 15 minutes.
Went together well. I changed out barrel to 14.7 .   Stock was good too w mil spec buffer tube.
Added a fake ACOG ... actually works pretty good.

QC needs some QC
2nd PSA upper and a 2nd disappointment. Dust cover spring was broken (short end that rests on the receiver). That was annoying, but fixable. I had to un-coil the spring far enough to make it right. That taken care of, my next pleasant surprise was that the upper prevented 20 round Okay Industries magazines from being inserted. At this point I am NOT amused. Looking in to the mag well, it was obvious that the radius of the front corners of the upper were too broad. I'm sure PSA would have made it right, but I chose the file option. 2 uppers. Shoulda, woulda been 2 warranty repairs. My enthusiasm for PSA is waning.

Don’t be dumb, BUY THIS KIT!
Awesome kit! These things shoot great, are light and handy and have that basic old school cool to them that I like. And at the price point you simply can’t get more firepower for the money.

Good buy, easy build!
This is a great product. After assembly and buying sights and clips it was cutting paper on the first shot! 4 shots later bulls eye!
