Thread: ar15 9mm barrels

Looking to build a 9mm AR for 3 gun based on the QC10, anyone know where I can find a suitable barrel in NZ?
Anybody got any experiences from building one vs buying the Stag 9t?

Unless your importing parts yourself, and the 9T is what you want,
Buy the 9T, you get local dealer support, you won't save anything on a 9mm self build,
Unless you import,


The glock vs uzi mag is another debate,

Oh and 10% off at gunsnz ATM, makes the 9T very appealing

9mm ar's are finicky things-having done a build on a qc10 glock lower I would have preferred to buy a complete rifle.
If you have the lower already then the gunstuff guys have barrels on the way

No haven't bought the qc10 lower yet as just tossing up whether I get a 9mm AR or stick to 223 and get a Colt Competition CRP for the same price. What's the recoil like In 9mm vs 223?

To hard to compare for me, to many variables.

Personally wouldn't get a ar9 if I didn't already have a 223 unless you have range restrictions.

I have the stag 9T.
It has more felt recoil than any of my compensated 223 AR's (Impact from the heavier bolt) but its far nicer to shoot as there is nowhere near the same noise and muzzle blast.
I can shoot it crazy fast and keep all the rounds on the target.
Do a search on Stag 9T on this forum and you will see my write-up on it.
I have had some ongoing issues (broken bolt catches) but NZGuns are working on sorting it.
I have no issues with the Colt mags. Buy a lula loader to save your thumb.

Currently have a HYDRA-multi caliber AR platform. 9mm uses colt mags - nice shooter, 9mm great to shoot & relatively inexpensive. Was looking essentially for a dedicated range toy, but the Hydra doesn't allow a lot of modularity...had a look at the JRC carbine etc but decided on a QC10 glock build (glock mags are readily available and easy to load) and thought I'd share some costings for those thinking about taking the leap.
Stripped lower & dedicated bolt - $1280
Raptor charging handle - $179.90
Anderson stripped upper - $176.90
Brownells 9mm buffer/Rock River 9mm spacer - $90
CAA buffer tube $99
Magpul qd sling plate $69.90
Buffer tube castle nut - $14.95
Buffer Spring - $30? (had a spare)
AIL fixed tube A Cat Stock - $299.95
BAD safety ambi selector - $139.95
Giselle Super Semi-Auto Enhanced trigger - $499.90
JP lower parts kit - $99.90
9mm barrel - $550
Handguard - $350 (budgeted as still undecided)
.....add 9mm carbine suppressor & optic....
Obviously added a few bells & whistles...dedicated package, or find buy someone else's project probably best way to go.

Yeah so about $3500 in the config that I was planning, which is identical to your build minus the non-critical parts like sling plate, ambi safety, flash charge handle. Love the SSA trigger in my CMMG so can't do without that
Could shave a little off maybe with importing some parts, barrels are almost under the $100USD mark

A barrel will require an US export license (+US$250 from brownells) even if under $100. So if doing that might as well stock up on any other parts at the same time as it is still $250 no matter what else you order.
