9mm AR Build

[Tejano Scott]

I have had a few requests and PMs for me to do a build thread for my 9mm SBR AR build. First, it's ironic that anyone would ask for this type of information from me since I know relatively nothing about building ARs. So the most important part of this build was recruiting the right build team: AaronP220 and Das Jared. Luckily for me I have friends with a wealth of build experience. I have however studied every forum and website I could find regarding the parts, etc. I wanted this to be primarily a range toy, but I also wanted it to accept Glock 9mm magazines. I love the Glock 9mm platform, I thought what better way to cement that love than an AR build thats Glock Mag compatible.

I've wanted to do this build for about 3 years. At first I was going to buy the lower from a company called Double Diamond Law Enforcement Supply (DDLES). A quick google search will find you multiple pages of customer complaints, etc. because the owner of that company would charge people for "in-stock" items and then deliver many months/years later. They went out of business and left a lot of folks without lowers. While I could have bought a DDLES on Gunbroker, etc., I passed because I just felt I couldn't support them. It was a shame since, by most accounts, DDLES had the best Glock Mag AR lower. Enter Quarter Circle 10 ("QC 10"). QC10 now owns the right/design of the DDLES lower. I've read several glowing customer reviews that they've been a very awesome company to deal with, so I decided to jump on it. They will not bill you or take your order unless the item is in-stock. I had to wait a few days, but sure enough their website listed them in-stock and I placed my order. Purchased 1 Glock Small Frame Lower which totaled with shipping, etc. to my FFL (aka my dad) was $290.60. They shipped it the same day as my order.

Immediately started ordering the parts below since it was going to be a few weeks before I'd be seeing my dad. Picked up the lower at Christmas Day Lunch with the parents. Took the lower over to Keith at NFA Investments to do the engraving. Form 1 is now filed. Once I get the stamp in a month or so, my expert build team will slap it together and we'll go tweak it till it runs right. Thanks in advance to Aaron and Jared.

What's the purpose of a 9mm AR or is a just because kind of thing?

Tag.

I love me some pistol caliber carbine. TACTICAL!

Have you ever shot a 9mm carbine? Tons of fun. Even the high points.

This.

I have an Uzi that's soon to be SBR'd and a CX4 that I got for the wife that will also get a trim. They are the most fun guns that I own and always the most popular with new shooters.

I'm sure 9mm AR is somewhere in my future.

 

[rl96ss]

Looking forward to this as well.

Poor Man's Mp5

 

[1slow01Z71]

That's quite the list of good parts man. You're going to be dang close to an MP5. Got any pics of that Quentin rail? Getting real damn tired of waiting on aero precision to make another mlok rail to cut down for my 6" 300blk build. You need to get into reloading. With all these 9mm guns you're stockpiling you need a steady stream of 147s.

I hate posting pics of other people's gear, but my upper will look pretty much exactly like this:

Pffft, better than an mp5

Sounds almost identical to mine.

FYI I had with the ssa trigger I couldn't get the jp buffer in the buffer tube. Hit on the hammer. Put it in the tube before you screw it in or like I did was take the hammer out and slip it in.

Also the buffer retainer is a real pain in the butt with the jp silent buffer. It would get stuck in the groove between the silver weights and it was a mother trucker to get it depressed so I could get the buffer out. I took the retainer out after that.

 

[Tejano Scott]

Well, there are definitely a lot of advantages of the 9mm AR Setup... Such as familiarity with the AR Platform and the Glock Mag compatibility. Plus, as with all ARs, its highly customizable.

Jared already noticed that about the buffer retainer pen... Thanks for the trigger/buffer advice.

Bummer I'm not a fan of the yhm barrel nut. Dang. You people and your 9mms haha.

Well, I have to disagree there....unless it's running 800 rounds a minute. I also think HK has a much better collapsible stock and the charging handle is in a better place.


But the price is much better on just about anything else.

 

[Younggun]

I prefer a 9mm carbine for home defense to a standard AR.

There, I said it. I feel much better now.
