I was assembling a lower recently, put it together, and found that I had a piece left over: a short, fairly wide spring. Looking at the parts diagram again, I realized I'd left out the disconnector spring  . I took the trigger group apart and put the spring in properly, which was no fun getting those holes to line up, I will admit, and now it's all together correctly. I have not yet fired the rifle, but everything seems to be working properly. What would have happened if I'd been careless and left the spring out? Fire one shot and then the trigger wouldn't reset for a second? |

Well, I took it to the range today and it worked fine (with my .22LR dedicated upper, haven't tried it with a standard 5.56). However, I think I may have put it in with the fat side uppermost. I guess I'll have to take it apart again Edited: Each time I do this it does get easier, I fixed the spring without much issue. I also fiddled with the Superior Arms set screw, which seems to be a very nice addition. My trigger makes a loud "click" when it resets, but since I've never used a single-stage AR trigger before I don't know if this is normal or not. |

I once victimized myself with an upside down disconnect spring. I was "lucky" in that I had to 'splain myself to the local p'lice, who had folks present when things went south. It could've been worse and had a round fire out of battery. Those who've done it, know what I'm talking about. |
Out-ok-battery = KB! Forget the spring and the rifle could easily blow up due to an out of battery detonation. When someone at the range has a gun that "doubles" (fires 2 shots w/ one pull) they tend to think "wow COOL!" - might want to let them know that they nearly blew up the gun and they had better STOP SHOOTING IT. They rarely listen though and I usually position myself a good distance away. |
Why schould it do that (kabum)heBy the way the powder schould burn ,,not detonate ,,burning powder pushes ,detonation chatters (also steel) to bits hould |
It's possible that, with the hammer pushing forward on the firing pin, that it will "scrape" across the primer as the bolt finishes it's final rotation into lockup. You can easily end up with a situation where the lugs aren't fully engaged, resulting in an OOB discharge that could well shear off lugs, vent gases into the magwell and upper, and send shards of steel and aluminum into your hands, eyes, and face. Then we'll have to call you "Lefty" and "ol' One-Eye". Or maybe "Scarface". You really, really |

So ,,just to be sure that im have not gone mad htWhat i am doing is (please try to do the same and post the result)holding the boltcarrier with my left hand ,thump on the same side as the ejector, index finger pressing the firing pin (as would the hammer if following) the 3 others on the opposite side as the ejector The bolt (not carrier) pulled out as it would be on the way chambering a fresh round still pressing the firing pin slowly pres the bolt into the carrier while watching the firingpin hole The bolt will rotate ,,then stop to rotate since the last part of the camming slot is straight And only after stopping rotating the firingpin will come forward ,at this time the bolt is fully locked ,so it can not kabum this way If you have bad primers (to chock sentisive )or reloads with not fully seated primers Or worst case a broken firingpin that i sticking in the bolt you can have a out of battery kabum (might be other possibilities) On all the Ar15 and M16 (c7) i have seen it is this way Stoner was not stupid ,,he knew what he was doing have Could someone try to do what i just did If you ever schould have a out of battery kabum its nice to know what to look for(fingers first hat Oh by the way have a look at this kabum http://www.liveleak.com/view?i=481_1181023978 |
| So ,,have anybody come to a different result than i have,,firing pin only comes forward AFTER the bolt is fully locked happenOr worst case a broken firing pin that i sticking in the bolt you can have a out of battery kabum (might be other possibilities)i |
