I ordered a Premium "Madness" Upper Assembly on Feb 1. Can hardly wait.

How do I know when it arrives, I got a PSA Premium M4A1(what I ordered), compared to the PTAC Upper Assembly?

Is there any "Visual Differences" that can be quickly seen, to distinguish one from the other?

Thanks

PSA Upper receivers sometimes / (most now i think) come with etched cross Cannons on the left side of the upper receiver.
barrel will be stamped PSA or Palmetto if its a PSA, PTAC wont. PTAC will just have 5.56 NATO 1/7(1/9) whatever twist.

Hope that helps.

The box will be foam lined, PSA logoed and labeled PSA M4A1 on the end. PTAC uppers come in plain unlined boxes.

The upper will have a laser etched PSA logo on the left hand side. PTAC uppers do not have a logo.

The barrel will be M4A1 profile between the hand guards. As far as I know PTAC does not offer a barrel with that profile.

The barrel will be marked PSA (along with caliber; twist; composition; etc.) between the flash hider and front sight post. The PTAC barrels do not have the PSA designation.

Madness uppers dont come with a logo so dont depend on that. I think the barrel markings will tell you what you need to know. Mine clearly says Palmetto.

PTAC's aren't chrome lined so you can visually inspect the muzzle for chrome and also the barrel markings usually state if it is chromed or not.
