Would anyone here know how or would build a 12.5 350 legend ar pistol upper?

any experience advice or parts advice?

thank you very much

P.S Roughly the cost?

You'd build it out just the same as any other AR-15 pistol (lots of tutorials out there on how to do this, it's pretty easy), just make sure to buy a .350 Legend barrel/upper. Just did some preliminary searching but I'm seeing .350 legend uppers between about 300 and 600 dollars depending on barrel length and manufacturer. Overall cost is going to be how much you want to put into it to be honest.

So the barrel is not interchangeable like 5.56 and 300blk thank you again. i don't have much experience with the cartridge but i see it everywhere, do you have any experience im looking at getting a 12.5in upper looking in aero barrels right now. I really appreciate you!

The barrels ARE interchangeable with a 5.56 or .300blk, sorry if that was misleading. .350 Legend was designed to work with an AR-15 pattern rifle for states that only allow straight walled cartridge calibers for hunting.

so i couldn't swap barrels between 300 and 350 legend, sorry i wasn't clear. i was wondering if i had to build a dedicated upper for 350. Thank you.
