Hey, what brand do you guys suggest for a 9mm pcc complete upper?

I'm gonna use my ar15 complete lower with the endo mag inserts.

I'm thinking 8-10" for optimal performance.

Aim has Foxtrot Mikes exclusive uppers for a decent price. Out of stock on 10 in though.

If you can, build your own with a Macon Armory "guaranteed to feed" or Taccom "superfeed" barrel. They feed when others won't. Feeding issues are the biggest problem with 9mm ARs. Assembling an upper is pretty easy if you have some basic tools and aptitude.

When you swap uppers on your AR-15, be sure to swap buffers as well.  The spring doesn't need to change, just the buffer.  Pick up an extended-length, sliding weight buffer and you'll be all set. Here's a guide to help with choosing the right weight: What 9mm buffer do I need??? (and spring)

While this is often true, especially with Glock mags, the OP is planning on using Endo's and the feed ramp geometry of those feeds anything into my BA 8.3" barrel with factory feed cone.  I would also suggest building, as AR-9's are simple affairs.

Granted, my only experience with these is on the two AR-V 9mm I have and which have run flawlessly for a couple thousand rounds

10" is $50 more

I always build my own 9's.  

Try it.  You will like it.

And it will be far better than a complete upper.

Ya I thought about building my own since I have the expensive armorers wrench. I already got 2 psa ar15s and they shoot fine, no issues. Was just wanting to try a different brand. I do like the foxtrot mikes and get a military discount with aimsurplus, so may go that way.

Thanks
