My 9mm AR-15 SBR Closeup and Build

do you know off hand if it's legal in California?

what upper and how about about

I do have to say, you are well versed on the subject! Excellent information and video! ^..^~~

From what company did you get your barrel/upper receiver and what length is the barrel?

Great video, i know this one video is old but are the internals the same as a .223/5.56 ar (meaning the fire control group/lower parts kit.)thanks . any help would be appreciated.

This was an awesome video! Really good build man. I also want to build a 9mm AR. Do you know if there is some way I can build one to work with my CZ75 SP-01 Magazines? I have so many CZ mags! Haha. It would be great to be able to use them.
Thanks for the video!

Can I use any AR 15 lower and just add the adapter? Or is there a specific lower needed for an AR 9?

IMO these builds are worth doing because you get the ability to fire far more cost effective ammunition without going to unreliable, underpowered, and now hard to find 22lr rimfire ammunition which more than doubled in price over the last 10 years… The 9mm chambering also allows the gun to be used at training facilities which ban the use of 5.56 on their steel targets.. And very unlike a 22lr AR, a 9mm build can be utilized as an effective fighting carbine with terminal ballistics very similar to a 357 magnum fired out of a revolver.. The bbti website shows the 125gr Speer Gold Dot leaving an 11"SBR barrel at 1360fps…. The same website shows the 357sig leaving the same 11" barrel at 1665 fps.. All things considered it would appear the true calling of the bottle necked 357sig is in pistol caliber carbines.

Can you use a dpms hammer with a unramped bolt?

What is the advantage of a ramped bolt? I looked around a bit but couldn't find where you said why you'd ramp it. Nice information, and delivery of it. I've done a lot of 15s and some 308s, and lookin to make a nice 9mm pistol

What's the total weight with the furniture you have on there?

On your form 1, did you glue your photo to the form, or tape.

Nice build!  Great breakdown of the parts you used. It really helped me on knowing what is needed to build a 9mm AR-15.  Thanks for sharing!!!

Wow, I didn't know there was so much involved with that. I am interested in a pistol carbine – not sure I want to build it, though.

I really like that sbr man

Very nice build ,,,,I am also building one 

Holy crap. I knew there would be some changes in design and operation but I had no clue it would be that drastically different. It looks so sweet though, nice job. Do you notice it being louder(or maybe quieter) with the longer barrel- like compared to a pistol- suppressed or unsuppressed?

Dat thing is friggin' sweet.

Thanks. Looks very nice.
