Thank you so much!!! Answered so many questions i had about building an ar9. I researched a lot of places and your short video answered all the important questions to build proper ar 9mm

[@biggerbehindthetrigger2814]

I had a issue with a BCA 9mm upper. The bolt binded up with the Stern's Defense Glock conversion. When I closed the upper and lower the Glock magazines would not release. I called Stern's and BCA. BCA said thier products work well with the Stern's Defense Glock conversion. Stern's said I should try thier bolt. The tech asked me to measure my bolt. I used my digital calipers and he gave me the tolerances and the BCA was so far out of speck. I just ordered a Stern's Defense bolt and it runs like butter. Sometimes going cheap ends up costing you way more than you expected.

[@KD-lb9bg]

I’d do a 22lr conversion for cheap plinking, but I think I’d just buy a dedicated 9mm pcc if I wanted one. Thanks for the great info as always.

[@lap9216]

I would only add one more thing. When torquing the barrel nut make sure it is aligned as if you were going to place a gas tube, IF NOT and you decide to put a Magpul handguard it will not be aligned properly because it uses the teeth on the barrel nut to do so. I am no expert but had that issue myself. Thank you.

If anyone is looking at this and wondering if they can save money without sacrificing features or reliability, I recently got a faxon 9mm BCG and barrel, an armaspec 9mm stealth recoil spring, and some mean arms endomag conversion kits. I had 0 failures to feed, fire, or eject over about 500 rounds. I know that's not a ton, but that is without any real break in with the parts. I also bought a rise armament blitz trigger as it is PCC rated, and that trigger is fantastic. I would HIGHLY recommend this combo of parts if you want to dip your toes into the PCC segment.

Did you keep the same 556 upper receiver?

[@gavingross2174]

@@clopez84 I didn't, but not because of incompatibility or anything. I ended up going from a side charging upper to another side charging upper, only difference was ejection port size.

This video is 4 years old and the 223 to 9mm magazine conversion kit wasnt available then, or he didnt know about the kits. They make a conversion kit whereby you remove the guts in your 223/5.56 magazine and insert the filler which allows the 223/5.56 magazine to be loaded with 9mm. This is SO MUCH nicer than what he showed in the video. You wont need adjustments on the bottom of mag well each time you go back n forth from using your AR-15 with 223 and 9mm, and you wont have to deal with the other other problems that are common with the conversion he showed. You just load your 223/5.56 magazine with 9mm rounds and shove the mag into your gun

Conversions don't make sense anymore considering PSA and others have dedicated lowers for 225-300. The mag adapters are still 175-200 even after yrs of being on the market plus the reviews are mixed. By the time you buy a barrel and bolt you're only 100 or so away from a dedicated upper. BCA is doing great things with 9mm also including a bufferless system. I'll let them work out the bugs and get a Gen 2 in a couple yrs though!

@@johnstreitt2474 - I’m a member of two gun clubs and do quite a bit of shooting, building, and reloading - including club PRS matches. Point being, I’ve seen quite a lot on the range. Every pistol caliber AR-type home build that I’ve personally seen has had FFE issues. I’ve seen some that work OK with one brand of ammo and are worthless with another brand - which tells you how finicky the gas systems are. Based on what I’ve seen - I would buy a known pistol caliber PDW and NOT build one. And I’ve built most of my rifles. At least if you buy something like a Kriss Vector then you’re not going to waste hundreds of hours and ammo trying to sort it out, and it will hold a healthy resale value. If AR pistol calibers were so easy, then Daniel Defense, BCM, Noveske, and the other major AR manufacturers would offer them. But most don’t and for good reason. Because frustrated, unhappy customers are what destroys a business. My two cents, YMMV.

[@homeFall1]

I just ordered a handful of endomags and a CMMG Rotationally Delayed Blowback barrel and bolt. I wanted to be able to use any of my AR lowers with that upper and think this will do the trick. Note that the CMMG uses an ejector mounted in the bolt so you either need the endomags designed for CMMG or you need to trim the plastic ejector off the mags. I ordered a few of both types of mags as supply is limited at the moment for CMMG mags and Oregon has BS Mag limits starting tomorrow so I wanted them on hand. I much prefer having the ejector NOT be part of the magazine so you can eject a round from the bolt/chamber with or without a mag inserted (endomags for most applications use the aforementioned plastic ejector on the mag so to unload you have to pull the bolt back w/ mag inserted, lock it with bolt catch then drop mag).
