Where can I find just parts or barrels?

I have a lower and want to build a 9mm, .40 S&W or .45 APC carbine and would like to build the upper myself. Who carries the various parts, barrels, and magazines that I would need. Thank you.

I spent about 20 seconds of effort on this…

Well, the links at the top of the page are a great start, Bravo Company for one.

Riflegear.com and RainierArms.com are two more.

Anyone can google I want recommendations from you, or maybe not you, but you get my point; that’s why we join FORUMS and not just type into google.

Thanks.

I personally deal with and run spikes tactical and stags products FWIW IMO they are GTG…

Take a look at Olympic Arms, they do a lot of pistol caliber AR’s.

Rock River Arms and CMMG are big in the pistol caliber AR market. Mine is RRA and works great. PK Firearms stocks a bunch of the needed parts too but the majority are RRA. If you are wanting something a little more exotic, take a look at DDLES and Lone Wolf. The LW takes Glock mags. 9mm Is the most common you will find but RRA is coming out with a .40 version. Not too many .45’s out there…check Bazooka Brothers for receivers.

i second DDLES. first class product and very pleasant to deal with. although, as far as upper parts, i think they only manufacture barrels and handgaurds

Thanks for all the info guys.
