Aircooled6racer Posted December 26, 2016 Share Posted December 26, 2016 Hello: I was wondering who makes the best Colt mag lower for a 9mm PCC build. Looking for a good built in magwell and large trigger guard area. Let me know what you guys are using. Planning on building a Colt mag PCC for next year. Thanks, Eric Link to comment
bmiller Posted December 26, 2016 Share Posted December 26, 2016 I own a PSA dedicated lower for colt mags. I have been happy with it. I built a magwell for it, mag changes are fast. A friend has a cmmg dedicate lower. It is made from a regular ar forging. So the magwell is full length. So the cmmg has a little extra weight from the chunk of aluminum in front of the magwell. It basically has the same chamfer around the hole. I made a magwell for him, it reloads just as fast. I would say the cmmg has higher quality anodizing. I don't believe he had to adjust his ejector, I had to on mine, nothing major. I am happy with the PSA, the anodizing is good enough for me. Link to comment
dcloudy777 Posted December 26, 2016 Share Posted December 26, 2016 I don't really have much to compare it too except an old Colt factory mag block receiver, but I'm very happy with my CMMG Mk9 lower. Link to comment
Aircooled6racer Posted December 26, 2016 Author Share Posted December 26, 2016 Hello: Ok here are the makers I have found so far. Gun Point, Black Creek Precision, PSA, QC-10, CMMG, and Rock River Arms. Anyone I am missing? Thanks, Eric Link to comment
Bamboo Posted December 26, 2016 Share Posted December 26, 2016 (edited) I'm pretty sure the PSA is re-branded from another manufacturer. I'm not sure what that manufacturer is. I know that CMMG parts fit, though. I have a blem PSA lower and have been happy with it, but don't know the differences between the various dedicated colt lower brands.

MikeRush Posted December 27, 2016 Share Posted December 27, 2016 I don't think it is available for sale yet but Patriot Ordnance Factory had a video of their new SMG up on FB. It takes Colt mags but appears to have a more generous magwell opening. I recently went Glock lower, but if I lived in a free state I would try to pick up one of those for sure. I've been disappointed with some small parts sold by POF but I think the receivers are generally well liked. Link to comment

ahub3101 Posted December 27, 2016 Share Posted December 27, 2016 I have a CMMG Colt lower that's been very good. As stated above, it's a standard forging with a Colt size hole in it, leaving plenty of material for the Dremel wizard in all of us. My bolt and barrel are CMMG also, they make good stuff. So do a lot of other outfits, too. Everybody I know has a different brand of PCC, they all work well. Link to comment
L3324temp Posted December 27, 2016 Share Posted December 27, 2016 I also have the CMMG lower. It runs flawless.Sent from my iPhone using Tapatalk Link to comment
Aircooled6racer Posted December 28, 2016 Author Share Posted December 28, 2016 Hello: I am narrowing it down to the QC-10, Gun Point and the Black Creek Precision for Colt lowers. All three take a standard bolt release instead of the 9mm one. They also seem to be very similar on how they are machined and setup. Anyone have any of those? Thanks, Eric Link to comment
2MoreChains Posted December 28, 2016 Share Posted December 28, 2016 I have a QC-10 lower for Colt mags. Its bueno. Link to comment
gatortommy Posted December 28, 2016 Share Posted December 28, 2016 I've got the Gunpoint M9 billet and really like it. In fact I ordered another one today- they've got them on sale right now for $164. Link to comment
Aircooled6racer Posted December 28, 2016 Author Share Posted December 28, 2016 Hello: I just ordered a QC-10 lower for the Colt mags. I will see how the magwell looks and how fast I can reload it. Little more money than I wanted to spend but as they say "buy once, cry once". It should work well with the uppers I am building. Thanks, Eric Link to comment
Aircooled6racer Posted January 5, 2017 Author Share Posted January 5, 2017 Hello: Still waiting to hear about the lower from Quarter Circle 10. I sent two emails over the past two days and no reply. They must be very busy over there. Hopefully I will hear something soon. Thinking of maybe going to Nationals and shooting PCC in March if everything works out. Thanks, Eric Link to comment

Also had applied for a dealer account earlier that was just approved as well. I think they had a lot of backlog around the holidays. Good luck with your build. Link to comment

TRUBL Posted January 5, 2017 Share Posted January 5, 2017 I want a lower that takes SIG MPX magazines!!! I'll bet we don't have to wait too soon either. Link to comment
Aircooled6racer Posted January 5, 2017 Author Share Posted January 5, 2017 Hello: If you need a quick response from Quarter Circle 10 Courtney is the one who gets it done. I should have the lower soon. The build will begin then. A big thank you to Courtney! Thanks, Eric Link to comment

I just happened to be quicker on the draw today.... Cannot wait to see the build! Link to comment
Dannybot Posted January 6, 2017 Share Posted January 6, 2017 (edited) Pics of the mag well on the QC10 Colt lower? Edited January 6, 2017 by Dannybot Link to comment
Dannybot Posted January 6, 2017 Share Posted January 6, 2017 Pics of the magwell on that QC10 Colt lower? Link to comment
Aircooled6racer Posted January 6, 2017 Author Share Posted January 6, 2017 Hello: When I receive the lower next week I will take some pics of it. From what I have seen in pics it has one of the largest magwells for Colt magazines. Thanks, Eric Link to comment

Bob Hostetter Posted January 9, 2017 Share Posted January 9, 2017 The PSA is made by New Frontier. Link to comment
blaster113 Posted January 10, 2017 Share Posted January 10, 2017 Have a CMMG lower in my build, along with a CMMG lower parts kit, bolt and barrel. So far the rifle has been flawless function wise. If I could do it over I'd start with a QC10 lower just for the looks. Otherwise I'm completely happy with the CMMG stuff. Link to comment
