hey hey hey ! been a while ,

so i bought this

http://palmettostatearmory.com/index.php/catalog/product/view/id/21685/s/psa-10-5-5-56-lightweight-keymod-9-freedom-upper/category/4220/

and i really wanted that with a 300 blk barrel so i bought this as well

who can see where im going with that ? give that man a cookie ! what are the odds the flash hiders permanently attached ?

I really REALLY do not want to have to cut a tacked flash tip thingie off , correct me later i forgot what it was called , you dont get a cookie

I have a spare upper stripped blem from psa but thats its no nut or tube or gas block or free float , so

am i gonna have to cut it ? or will i be lucky and just get to strip it and swap barrels or do i need to just order the rest of the parts to

finish the other upper ?

I don't think it is pinned and welded, you should be fine.

 

I don't have a PSA 10.5in upper but my 16in PSA upper has just a crush washer on it for the muzzle device.

You should be good to go on swapping barrels.  All you will need is a pistol length gas tube.

wheres the thanks i do not see it ...

the barrels in question are the same lenght! the upper is 10.5" barrel and the barrel i ordered is 10.5 "

Hopefully i can swap , then start tax stamps! muhahahahahAHHahAHAha ...

And a flash hider or other muzzle device.

Good catch, he will need a 30 cal muzzle device and maybe another gas block.  Not sure if both Barrels will accept the same size gas block.  I did not see where PSA listed the gas block size on the barreled upper.  .

Ow dang , that i did not know , i was planning on keeping it in the safe until tax stamp, then i was going to look for a ratchet on break,

something like the YHM can system uses maybe.

But the gas block issue i was totally unaware of that I though i could use the same low profile one from the 556.

I will start reading and google'ing and worst case ill order one. nothing but time until its time to shoot some hogs

They should both use a .750 gas block so I'm sure you'll be fine. Now the gas tube on the other hand you'll probably need a pistol length for the 300BLK.

I just read the PSA description and the barreled upper does use a .750 gas block.  All you will need is a pistol gas tube and a muzzle device.

So i wont be able to use the gas tube from the PSA upper ? i thought it was a pistol built 556 upper ?  i believe I am cheating my
way into a 300 blk the cheap way , upper was 249 shipped for the 556 and barrel was 98 shipped , 350$ and I get a 300 blk upper with keymod rail!

No the 5.56 barrel has a carbine length gas tube. The 300BLK barrel uses pistol length gas system.

DAMN! that 556 Upper sold out FAST it was available last night, now its gone!  so glad i got my order in!

Thank you! thats a relatively cheap part! will score one at my local parts shops...

you guys are awesome ! i got shipping confirmation on teh barrel today! upper should be tomorrow and im hoping to have them in less than 14 days!
