Posted: 1/21/2016 9:43:17 PM EDT

any one else having this issue. its hands down the biggest pain in the ass ive dealt with as far as guns go.
it fails to eject every time. its strictly a ejector issue. not a bolt buffer or spring or bcg issue

If your ejector wiggles then it need to be shimmed so it doesnt move. After you get thet fixed put your bolt in and bend the ejector twards the center untill it just about touches the bolt. That should fix your problem

It's too bad you can't get a hold of QC10 and actually talk to somebody, their customer service sucks!

Are these ejector issues mostly just with the Glock pattern lowers, or does Colt pattern lowers have issues too?

I'm just now finding out about thier CS. Unfortunately I have thier lower in a pending F1 or I'd sell the damn thing.

Speaking form my personal experience, I own the QC10 colt lower, ejector wiggles and it still ejects everytime, no problems.

I have not heard anything bad about QC10.
If you are trying to call them this week, they may not be too responsive as they are at Shot Shot.

There are several things that can cause the problem you are having. Maybe mad machinist will drop by and offer his insight.

Hi DeathB4dishonor,

I am the technical support for Quarter Circle 10. I'd like to help you with your build, could you please tell me a little bit more about your build? The ejector is rarely an issue on our GSF builds. Could you describe your set up in greater detail? Everything from your buffer weight and spring to the trigger you're using. What caliber are you shooting? Suppressed? What types of jams are you having stove pipes? Do you have any pictures of the issues you're having? You can email me at [email protected] if you feel more comfortable sharing pictures that way instead of here but it could help someone in the future with an issue.

EXCELLENT! I am getting ready to start a build with a QC10 lower so this discussion will be very helpful. Thank's for taking time away from The Shot Show to address his issue.

I never had any problems with their CS. Everytime I've call I had someone answer. I would think this week would be a problem because of the shot show. Call them next week.

Posted: 1/22/2016 5:08:54 PM EDT

[#10]

thanks for your response, but it is 100 percent the ejector. if the gun leans any bit left of center the ejector moves left and never even touches the spent casing. the gun should rack the ammo if im manually ejecting the rounds. it doesn't unless I lean the whole gun sligtly right so the ejector lays on the bolt. the mad machinist told me the other day that this is a poor design and says this is very common with this floating ejector. I really am in love with this build but this is rediculous

Posted: 1/22/2016 5:13:51 PM EDT

[#11]

I have no intention of being rude. but the facts are fact. your right they hardly answer the phone. they also shipped my package incomplete over the holiday sale. then couldn't be reached at the time I took delivery from the ff, l so I could have a witness tell them they shorted my on my order. I was trying to cover my own ass there so as not be questioned as a liar or cheat. they did fix that issue now im dealing with a ejector issue that people want blame on something else.

so im a little butt hurt about all of this

qc10 glock 9mm lower
new frontier bolt glock cut
gibbz side charging upper and gibbz foreend
Wilson 7.5'' barrel with flash can
milspec lower parts kit
pistol buffer tube
9mm dedicated heavy buffer
carbine spring
115 grain ammo.

it will not cycle out spent rounds or new rounds via the ejector. if you look thru the mag opening you can see the ejector favoring what ever side you lean the gun to.
the bolt grabs the round nicely pulls it back wards from the barrel but the ejector arm fails to fling it out ward

Posted: 1/22/2016 8:42:00 PM EDT

[#13]

FWIW, I have the same lower and the ejector on mine has plenty of wiggle side to side, but it has functioned perfectly since round #1.

Perhaps it is a specific combo of parts that the pistol dislikes...

im interested but id have to make some plans for it first. im a foreman for mechanical company so time it is hard to get lol. I did shim it with tooth pick and it works pretty well but I need a permanent fix. I still think this is a lame problem to begin with.

ill call you Monday again. if you don't mind. im running the family to Miami tonight for dental conference that my wife is attending, so ill me mia till Monday. thanks for chiming in, its odd there's no response from qc10 on here after the build list was posted

I have a few extra ejectors left over from DI guns......found one under my laptop on the black hole I call a desk this afternoon...

...I will see if I can get one reverse engineered into a solid model and have my laser guy cut some out of thicker material to fit the slot if anyone is interested in one as a replacement.....then it is a simple matter to just mill the hook portion to proper thickness.....
In the meanwhile.....let me look and see if I have any shim stock that will fit in the slot with the ejector and fix it in place......if so...I can , or you can, just cut a shim and you can super glue it to the ejector to hold long enough to get it installed.....once in the roll pin will keep it from moving.

Hello all

I am one of the owners of the company and I have sent an IM to DeathB4dishonor and I will resolve his issues.

The GSF and the GLF are a different animal than the colt platform. With the colt you can put most any part on the gun and it will run. The GSF/GLF not so much, The feed cycle geometry is somewhat more complex. We have spent a great deal of time working on the combination of lower, bolt and barrel, engineering them to work together and function every time, our bolts and barrels are just a little bit different. I have zero experience with new frontier bolts but I know that failure to eject is not an issue I have had to deal with before.

Please in the future IM me or ChrisAtQC10 if you fail to reach anyone at the shop.

No sweat Chris.....I am familiar with the bolt he has as I had a hand in the conversion of it to run with your lowers when the change was first made, (they are made by a good friend of mine) and have a BUNCH of them running on your lowers.....first I have ever heard of this as well......

I own the GSF lower from QC10 and there is some play from side to side. But has function great in that regard. Sorry to hear of your trouble deathb4dishonor. They are a small company and at times has been hard to get someone on the phone but Danny there has always been quick to reply to my emails.

Colt QC10 lower here, and mine has functioned fine after getting the ejector fitted. It required a bit of filing to clear the bolt when the lowers were put together, but QC10 hooked me up and sent a spare ejector to fix the issue, and no problems since, and mine is on a form 1. Fun little toy to play with suppressed.

so I was promised a ejector replacement for free no later then Wednesday. so it didn't happen. i called Thursday after work and still wasn't here. now they say it shipped over night which would have put it here Friday or Saturday at the latest. now I wont see it till Monday. this is a another weekend that has passed, that I've yet to be able to shoot. due to poor business and lack of communication from employees to owner and vis versa. the owner offered a 100 dollar thanks for being patient refund. yet I still haven't heard any more about that either.

so go ahead and flame me ar15.com users. tell me its cause there a small company and tell me I don't know what its like. the fact is I due know what its like and this is BS. Ifi buy a car for 30 grand its gonna work or If I buy a fucking 1 off pistol from jimbo the one man custom pistol gu. y its gonna work. Or im going to do the same thing im doing now. ive been beyond patient enough is enough

For those that do not know, I am one of the owners of Quartercircle10. We take customer service very seriously. This incident was a failure on our part on several levels and I take complete responsibility. I could give you a list of excuses but we all know what they are like. I have talked to DeathB4dishonor and understand his frustration. We are taking steps to change how/who handles customer issues and in what time frame.

There are two options moving forward: 1) We can offer DB4D a full and complete refund 2) We can work with him to make this right to his satisfaction. I will be contacting him today.

Just saw this thread. I built an SBR with the QC10 lower and it has been 100% for me both suppressed and unsuppressed. Never any issues.

The ejector on my lower wiggles a bit as well, but never a problem spitting out the empties. Would get them again without hesitation.

I'd REALLY like to see what is causing the problem........cause I have never heard of this issue before either......

Russ is a GREAT guy and I have a lot of respect for him........not trying to step on toes here.....just have had a lot of experience building pistol cal uppers and want to hep a member get shootin.....it is amazing how easy it is to drop the ball when you grow at a rate much faster than expected......it happens to us all now and then

Russ personally answered an email I sent in and I thought that was outstanding for him to take the time to do that.... That move, right there by Russ, told me I was going to be dealing with a company I could work with. I am in the planning stages of my first build and first AR 9. I am going with the QC10 Colt Lower, QC10 CLT Bolt Assembly, QC10 5.5" barrel and will purchase the QC 10 side charging upper if it becomes available in time. I have not heard many complaints about QC10's customer service and surely not enough to deter my trust in them. Sorry to hear DB4DH had issues and hopefully he will get them corrected. I have been in his shoes with other purchases I made and I totally understand his frustration. I am chalking it up to an isolated incident.

im not saying Russ is a bad guy. im saying this was a bad business situation, which may are may not be due to him. it could have been his employees slacking on quality control. as far as a quality replacement part . I finally got it yesterday, which was two weeks longer than it should have taken . Im still waiting on call back from Russ, he wanted to talk to his Partner about some other issues we spoke about.

What I don't understand is why everyone is so gun hoe about how great they are. this maybe true but even the best fall and fail. but for reason my post has been hijacked by all of you seemingly trying to down play my situation. yet again whether its big business or small its the company's responsibility to provide a working product to the costumer. if that's not how business works then my 35 years on earth ive been lied to.

thanks Russ for the part. but I am still waiting on the other business we spoke about.

Your feelings are mutual OP, it's not just you. I believe they lack the man power to properly address problems that arrive and also lack in timely delivery of their product. I believe we are experiencing their growing pains right now and this is what it's going to take to do business with them right now.

Greetings,

Yes, same here. When I first built the carbine, I though the floating ejector would be problematic due to the degree of "wiggle" and need to be shimmed. However, it's worked 100% for a few thousand rounds without issue. Only thing I can think of is I have an RRA bolt ramped and Glock cut by ADCO. Perhaps there is some bolt difference that is causing your ejector to float too far over? Hope you get it running and good luck!

Regards, Jim

EDIT: PS, just thought of this...................my Small Frame Glock Lower is actually an early DDLES (the company who is now QC10). I don't know if there have been any changes to the ejector design since the company "re-org". I know that QC has been doing other refinements such as with the LRBHO, perhaps other changes have come along. So, my experience may or may not be relevant to your lower.

Greetings,

Good to hear from at QC10 Rep. I think it would be a big help if you could post here or on your web page any differences between the earlier projection DDLES Glock mag lowers and your current design. That would help us all to support each other without some possible inconsistencies. It would also allow those of us with the early lowers to keep up with any improvements (that are hopefully backwards compatible). Thanks!

Regards, Jim

I too had/have this problem. Tried everything and finally sold it to a friend that said he could fix it; it is now back in my hands. It damn near broke my spirit when it worked for a minute and then went back to fte every round.

I have a bewildering array of 9mm parts - buffers, springs, uppers, and barrels from this mess. QC10 tech support was responsive via email, but we never got anywhere. I'm at the point where I just put this in the corner of my reloading room and ordered a CMMG lower for Colt mags. Lesson learned and moving on...

Uppers tried - VLTOR MUR-1s, Black rain billet, PSA
Barrels tried - Adco, PSA, Spinta Precision
Buffers and springs - which ones haven't I tried?
Triggers - tried PSA and others
Magazines - Glock factory
Bolt - NFA (the only other constant other than the lower)

I am just now researching for parts and find it bewildering how many tweaks seem to be needed with every product I have run across. Many or most I would say are also out of stock, so it makes me wonder if someone has a great product why wouldn't you make more? And if you're selling out and if your product has problems why not get them fixed fast cause the platform seems a hot seller.

I know this might be a little off topic but does someone have a rock solid platform? In stock preferably? Thank's for any response.

Posted: 2/24/2016 10:35:54 PM EDT

[#45]

Think about it......it is very expensive to make all the parts and test them as a system for something like a 9mm glock AR carbine...so companies make what they can...It would be nice if there was a standard for all the various components.....but who sets the standard....who chooses which MFG's design is the best.....and once that is decided.... who convinces that MFG to distribute prints to everyone else out there.....

I picked up ejectors late this afternoon.....drove an hour and a half to my laser cutter's to get them rather than wait on shipping so I can start testing in the AM....

Posted: 2/25/2016 11:08:11 AM EDT

Ran the 9mm this morning......and still had the problem.......no more than two rounds without a failure to eject....put then new ejector in.....ran a 30 round mag with zero malfunctions, will run a couple of hundred through the day and report back......

Edit....All together I ran 120 rounds today with the replacement ejector......no malfunctions........one of my barrels and an NFA and CMMG bolt. would have run more but feeling rough so went home and am on the couch under a blanket with my laptop.

I have been very unimpressed with QC10.

At the Shot show I talked to one of their reps about a problem I have, he scanned my tag and said the tech support people would contact me. Waited a month after Shot and nothing. Sent an email relating to this to QC10, nothing. Tried again after a few weeks, nothing. Tried an IM and email to the QC10 person who had replied in this thread, nothing.

Seems they employ a lot of crickets at QC10..

Posted: 2/26/2016 12:29:23 PM EDT

[#49]

I see QC10 all the time posting photos on Instagram. Hit them up there also. never hurts to try. I bought an Angstadt Arms receiver set and every time I have emailed or called with a question, Rich Angstadt himself has replied to me. I have nothing but good things to say about them so far. Yeah the price seemed high at first but the customer service I have gotten has been great. Rudy also has nothing but high praise from me for his(and his wife) great customer service.
