Looks like I built a AR 9 now......

Here is a TTAG review of the Lone Wolf G9 receiver - http://www.thetruthaboutguns.com/20...-g9-ar-15-lower-receiver-for-glock-magazines/

 

[Mac11FA]

This looks like the best deal, unfortunately they are out of stock!

Looks like this is the best deal on an available BCG:

When you finish your build, please supply us with a parts list and a range report!

Will do. It will probably be a little bit, been overly slammed at work.

So when building the ar 9 what is a good barrel length?

Is there any major differences between a pistol and rifle length upper?

if suppressed, the general thinking is that barrels less than 9 or 10" will keep 147gr ammo subsonic. there is some variability to this. my 7.5 keeps 147s at subsonic velocities.

I'm sure there's a lower limit but I've seen 4" that work when suppressed (and maybe even not suppressed)

other than that, gotta watch out for atf regs. if you are using a pistol lower or sbr, then not a problem.

also, keep in mind the clearance necessary under a hand rail or free float that you'll need with a can if you go this route.

All lengths should keep 147 subsonic unless Yosemite sam was working the powder that day.

The barrel length has nothing to do with the reliability, it's direct blowback. Generally the less barrel there is the less likely you are to experience port pop. I used 5" on mine.

 

[Cudruln]

Do you plan to suppress it?

I currently do not have any suppressed items. It is something I am looking at doing in the future. So to answer the question it is possible that it could be suppressed at some point in its life.

 

[Cudruln]

I would like to go the pistol route (sbr in the future). So what would be a good barrel length that can work with or without the use of a suppressor? Do I need to be looking for a 7" or would the psa 10.5" kit work?

 

[NWS]

Any length will work. Whatever you prefer.

They'll all work but less barrel means less time with pressure in the barrel that may escape at the port.

Thanks for the info guys. I will be continuing the search today.

Alright please excuse my ignorance, but I have never really gotten into glocks. So when they say small frame pistol magazine, do they mean single stack or what? Pretty much what magazine from what glock will work with this lower? Thanks for helping this dumb ass out.

9mm, 40, 357 sig

9mm, 40, 357 sig

So with glocks all magazines are the same size, just different calibers?

Small Fram = 9mm, 40, 357, 45 gap
Large frame = 45 acp and 10mm

Awesome thanks for the info. I learned something new.

And more 33 round mags...

This one is going to the range tomorrow-

That's nice man.

That's nice man.

Thanks! I was impressed with it at the range. Pistol caliber carbines are really fun toys- I've got to get some more time in with this one.

Another relatively inexpensive BCG to use with Glock mags:
