300 BLK pistol uppers question

[RA8]

Anyone have any input on either of these, I don't see a reason why I would need to spend the extra 100+ for the PSA parts.

PSA 300 AAC 12" SQR 11" Pistol Upper NO BCG or Charging Handle

RF 8.5" 300 AAC Quad Rail Pistol Upper Assembly

I have a 8.5 " with seekins rail from Radical and have been very pleased with it. Just put another 50 rounds through it today and now have around 250 rounds through it. I have only shot supers through it so far and plan on a can for it hopefully sometime soon.

thank you, and since I'm only using this thing for close range I think the price is right.
