rr4406pak Posted January 9, 2018 Author Share Posted January 9, 2018 Just an update from my original post... Four months later after a world class gunsmith tried to fix it: -Aftec extractor was installed and tuned. -Ejector filed and tuned. -Found the chamber was out of spec and not machined properly, so he reamed it out to proper dimensions. Result? Nothing but FTE jams. Can't make it through a single magazine without this: Link to comment Share on other sites More sharing options...

Is there any truth to this? A lot of us have found cmores don't hold zero well no matter how it's mounted. Mount it how you want and check it often.

Bdh821 Posted January 9, 2018 Share Posted January 9, 2018 If you have issues, call Ryan Youngblood. If he won't talk, ask for Zane Maddox. If he won't answer, ask for their boss, David Cupp. Link to comment Share on other sites More sharing options...
Steelix Posted January 9, 2018 Share Posted January 9, 2018 Yep just put a RTS2 on it and be done with it. why would you want 90 degree slideride blocking your view. Link to comment Share on other sites More sharing options...

I have an RTS2 on my Trubor... They are shorter. The part of the slide mount that is contacting the cases in your pictures doesn't exist on an RTS2 mount because the sight is shorter... I'm using the Brazos RTS2 mount on mine... also a Brazos ejector... and a Aftec extractor... Link to comment Share on other sites More sharing options...

I can find a 90 degree mount for around $70 and be up & running (or so I hope). An RTS2 with the mount would be ~$450. This gun is doing nothing but draining the bank (and I'd rather be putting $ into ammo). Link to comment Share on other sites More sharing options...

shooterDrew Posted January 10, 2018 Share Posted January 10, 2018 Sell your original mount and optic separately. You’ll get 50 for the mount and 175-200 for the optic without breaking a sweat. Making the upgrade cost about 150$. If it’s not worth 150 to fix at this point I don’t know what to tell you. For me personally, I wanted a dvc but was aware of the possible issues. So I dropped that 150 at the front door and had a gun that ran perfect. Why Sti doesn’t go with it set up that way from the start is another conversation, but it will fix your problem as proven by tons of other people.

rr4406pak Posted January 10, 2018 Author Share Posted January 10, 2018 Removing the optic it's easy to see where the brass was impacting the Cmore & mount: Gun ran flawless without the optic on it (as many of you stated). Brass ejection pattern was all over the place. Straight back, then perpendicular to the gun, then sometimes arcing high, sometimes no arc... no discernible pattern.

RonPogi Posted January 10, 2018 Share Posted January 10, 2018 Try use new magazine like MBX, that's what happened to me installed everything it turn out the cause is the magazine. Link to comment Share on other sites More sharing options...
rr4406pak Posted January 10, 2018 Author Share Posted January 10, 2018 I am using all brand new MBX magazines, so the magazines are not the cause. Thank you for the suggestion though. Link to comment Share on other sites More sharing options...
RonPogi Posted January 10, 2018 Share Posted January 10, 2018 (edited) I suggest filing 1/4 of the ejector's top half ( top right corner) at a 20 degree angle and 3/4 of its bottom half (bottom right corner) at a 60 degree angle. However, your measurements may differ from mine since they vary depending on how long your ejector is. Edited January 10, 2018 by RonPogi Link to comment Share on other sites More sharing options...
HoMiE Posted January 10, 2018 Share Posted January 10, 2018 Can you take a pic of the ejector? I like to have a slight forward angle on the vertical face so it hits the case High and around 5 degree to the outside. If the extractor tension is adjusted properly with enough tension to hold case it should eject straight out and not up. Link to comment Share on other sites More sharing options...

Didn’t fire a shot with the slideride on it. As soon as I got the gun on went a DPP and I never had ejection issues. Link to comment Share on other sites More sharing options...
Aircooled6racer Posted January 10, 2018 Share Posted January 10, 2018 Hello: I had to change out the ejector since the original one was soft and kept bending. I used an EGW extended one and ground it flat so it ejects sideways. I also put in an Aftec extractor and cut one coil off the front spring. Lastly I changed out the firing pin stop and radiused the area where the Aftec touches. Check to see if the firing pin stop has a radius and try the Aftec with no front spring. This is with a STI factory upright mount and C-More slide ride. Thanks, Eric Link to comment Share on other sites More sharing options...
traingq Posted January 11, 2018 Share Posted January 11, 2018 My STI Matchmaster did the same thing, once I had my gunsmith tune the extractor I had no more issues Link to comment Share on other sites More sharing options...
andersonj55126 Posted January 12, 2018 Share Posted January 12, 2018 Can you take a picture of the gun with the slide off and loaded magazine inserted. I would like to see ejector shape and bottom clearance to the next round. Are you running 1 or 2 springs with Aftec? I recommend 1 spring in the back position. What is your recoil spring and is possibly binding and not allowing full slide movement? Delta Point Pro is the easy fix. Link to comment Share on other sites More sharing options...
Bdh821 Posted January 12, 2018 Share Posted January 12, 2018 (edited) I've had 0 issues since I put in an Aftec with 2 springs that are squished and a DPP. Also, since I'm a southie, with my thumb rest, I've had 0 issues. Ejector is stock and I use MBX mags Edited January 12, 2018 by Bdh821 Link to comment Share on other sites More sharing options...
