Both on sale at psa for 249

Mid one

Mid 2

It would appear from looking at the descriptions they are identical.

Always thought PSA had WAY to many similar products... just my 2 cents.

That's why I posted it here ... I couldn't tell .

Either way , I ordered the one that ha A2 in the description like

barrel profile, one is lightweighted, the other one modified A2 profile

This is the answer.

To OP...I would be real wary of buying anything they have modified...see this thread:

http://www.ar15.com/forums/t_3_118/655154_PSA_Midlength_Freedom_Stainless_Dissipator__Fo_or_No_.html&page=2

Read page 2...at least.

I wonder if that problem is only with the dissy builds ?

THEY didn't modify the barrel, they had it made to a "modified A2 profile" by their barrel maker.  And it's a standard upper that they've made lots of without any major uproar about it - unlike the dissy issues.  I get your being ticked about this, but I think it's a completely different kind of product, and not one that the kind of problems that cropped up with their stainless dissipator models.

OP, the price is almost too good to pass up.  For another (roughly) $120 you can get their "premium" unmarked BCG and a standard charging handle, so a complete upper would cost you roughly $420 plus shipping.

I added the $99 deal for bcg and charging handle

After shipping it was $375 . Not bad for a complete middy upper

that is the same bcg just no laser engraved crossed cannons.
