    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?

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

    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.
