Last trip to the range I had three separate incidences of two rounds being fired with a single trigger pull. I fired a total of approx. 60 rounds before I decided I better quit before I gave the range master an anxiety attack. ( It was right before the firearm deer season and the line was packed with the usual one box a year shooters- figured he enough on his mind without me adding to his worries.
Rifle: Romanian SAR-2 (approx. 3000 rnds run through her) G2 trigger (probably less than 500 rnds with this trigger) Ammo: 5.45x39 Wolf 60gr FMJ "the newer" non-lacquered case. Rifle was relatively clean, but certainly not squeaky clean. I've never had any function problems of any kind before, ever. I took it home and cleaned the rifle well, giving special attention to the firing pin and channel. Anything else to look for? Could something else be causing this? Maybe some softer than usual primers? |
That may have been a BUMP fire, not slap
If you dont have the rifle snug on your shoulder this can easily happen. If you have a light finger on the trigger this can easily happen. Worst Case: possible issues w/ your FCG or disconnector spring. If you dont have a Tapco G2 in there now, i would replace it with one. |
| Check that your hammer/trigger pin isn't walking out when you fire. If that is the case and the original trigger group was replaced for the Tapco G2 they may have used the same Hammer Pin Retaining Spring (Shepherd's hook) that came with the original trigger and they can fail especially if you've been messing with them. If this is the case replace the Hammer Pin Retaining Spring with something like a Krebs retaining plate and you should be good to go. Let us know what happens. Thanks |

Letting the rifle sit on a rest, barely touching the trigger... PaPow! One shot on target, one shot off paper. |
You prolly just need a little more disconnector engagement. Any competant gunsmith could do this for you in about 5 minutes.

Hold the trigger and lock the hammer back... when you slowly (very slowly) release the trigger, does it release the hammer? Best answer here so far and I strongly suggest you try what he suggested above. One of the reasons I returned my Tapco G-2 is that the fit on my SAR-1 was such that the disconnector wasn't holding on to the hammer long enough for the sear to catch it when letting off the trigger. This would allow the gun to double-fire occasionally with a single trigger pull (dangerous). Anyway, I did my research and the G-2 trigger set was modeled after Bulgarian trigger groups. Romanian trigger groups are slightly different, but apparently it's enough to make a difference on some SAR's. Look around... there are other FCG's out there (and I'm not talking about something fancy like Red Star Arms either). I tried digging through my emails to find out where I ended up getting my current FCG from (sometime back in 2005 or 2006) but to no avail. It was something "brothers." |

Ok, I followed the advice above....
I held the trigger back, charged the bolt and let it fly forward (while still holding the trigger back). I slowly let off on the trigger and the disconnector disengaged, then the single trigger hook grabbed and held the hammer. I repeated it several times with the same results. Good to go, right? |

Replace the disconnector spring anyway. It is a $3-6 part depending upon where you buy it. Cheap insurance.
Another test you can do - load a mag with one round only. Fire it and then pull the trigger again on the empty chamber. If you hear the hammer fall, all is well. If not, problem. And get a solid shooting stance with that thing pulled TIGHT into your shoulder! |
