deric brunette 3 Posted November 25, 2010 Report Share Posted November 25, 2010 Hey peepl. I was having a problem with my S12, Failure To Eject the spent round. I had lots of tips and hints and info from alot of great peeps. Here is wat i did to fix it. I started with polishing up the bolt and bolt carrier. Have a nice finish and it did feel a little smoother. Ok back out to my buddys house to try it out. Using Federal 1/8 birdshot I loaded up my 12 Rnd Mag. Setting 2 for light loads Fired, and failed, cleared the round with my hand, round 2 fail rnd 3 and 4 all failed. Fumes mentioned in one of our conversations(thanks fumes)taking off the aftermarket guard or rails and puting the stock guard back on. so I took off the qaud rail, reloaded the mag . This is wat i got . shot 1 through 12 fed awsome every shell ejectect with no failures. 2nd mag12 rnds again with the gaurd off. as fast as i could pull the trigger 12 rnds all ran great no failures. so i put the gaurd or rail back on and clamp it up tight. Next mag rnd one fail, rnd 2 fail 3 4 5 6 7 8 9etc all fail to eject. Took the top rail off of the two piece guard rail so i could use the forgrip left the bottom pice on. next 2 mags all rnds cleared as fast as i could pull, no failures. So Im guessing the qaud rails clamp down on the gun too tight and causes the weapon to FTE. I hope this helps anyone who has this problem. My shoulder is alittle sore today but it was fun after I wored out all the bugs. Again I just wanted to say thanks too everyone for all you coments and info and suggestions they helped. Ill try to post pics of it when i get a chance. Have a great turkey day everyone. Quote Link to post Share on other sites
RABIDFOX50 6 Posted November 25, 2010 Report Share Posted November 25, 2010 I have the Chaos quad rail but Cameron designed it to work with the gas relief hole on the side of the gas block. It also does not clam to the gas block. It uses the factory hand guard mount. What one did you have? Quote Link to post Share on other sites
Fumes 84 Posted November 26, 2010 Report Share Posted November 26, 2010 Cool glad you were able to diagnose the problem without going overboard right off the bat. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 Thanx fumes great help. I got the UTG quAd rail. I did use the mounting hole but it clamps together. I think i can make some spacer platz so it tightens up without clamping too much into the gas tub. Quote Link to post Share on other sites

Thats kinda what I was thinking, just an oversize hole, should be fine I'd think. Worth a try anyway. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 No the rail doesnt obstruct the hole at all. It was how tight the two piece rail gaurd was fit. If it was tightened down enuff it wasnt secure and would wobble. So it clamps down on the gas tube kinda bending it when it was tightened enuff to not wobble. I have the same type of rail for my saiga .223 and it runs fine tightened all the way down. But i took it off and shot it with no gaurd or anything and everyshot ran great. It beat the shit out of my shoulder though lol. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 I dont know if this pic will come out to goog this is my S12 with the top rail guard off and this is when it shoots fine. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 this is my S12 with the Top rail on and the rail clamps onto the weapon to secure it. When clamped on the gun Fails to Eject (FTE) the spent round. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 See i dont think it obstructs the blow hole. LOL, i just made that up, blow hole. Quote Link to post Share on other sites
datubie 21 Posted November 26, 2010 Report Share Posted November 26, 2010 When you have your top rail on, did you check if the 6 cap screws are touching the gas tube when fully tightened? Also, how far did you tighten the upper piece to the bottom rail piece? I did not crank the 4 screws all the way down and have slighty less than 1/8" clearance between the upper clamp piece and the bottom rail. Quote Link to post Share on other sites
deric brunette 3 Posted November 26, 2010 Author Report Share Posted November 26, 2010 I didnt check the space just made it tight enuff not to wobble. But every shot with the top clamped on FTEed on me and i take the top part off and flawlessly it ran. Quote Link to post Share on other sites
datubie 21 Posted November 26, 2010 Report Share Posted November 26, 2010 Hmmm... I think a less than straight op-rod causes the FTE by slightly rubbing on the gas tube. I know mine rides less than perfectly centered within the tube. I didnt check the space just made it tight enuff not to wobble. But every shot with the top clamped on FTEed on me and i take the top part off and flawlessly it ran. Quote Link to post Share on other sites
