I have a RR SP1 coverted to F/A.
Recently the gun started to double when shooting on SEMI. I had the FCG replaced with all new parts, test fired the gun in SEMI and F/A and it worked greyt. I could even see where the old disconnector was worn. I then used the gun in a 2-day Patrol Carbine class and it worked flawlessly the entire time - 750 rounds down range in SEMI (and the best I ever shot  ).
Now the gun is starting to double again during deliberate slow SEMI fire. And on top of that it went F/A while I still had the selector on SEMI. WTF! 
So this is less than 1000 rounds on this FCG. I looked and there is no sign if unusual wear on the disconector that I can see - of couse that doesn't mean that its not there. Any ideas of what's going wrong or potential remedies to keep the gun in SEMI when I want it there and F/A when its time for fun??? |

Bump. Anyone.........???? Any ideas....????? Doubling is damn near always a disconnector problem. If it was fine and has started again, then the disconnector is likely the problem (again). Perform the disconnector function check - with the weapon cleared and pointed in a safe direction, charge it, then press and hold the trigger. Charge again, then very slowly let off the trigger. If it lets the hammer fall instead of being grabbed by the trigger, then you have insufficient disconnector overlap with the trigger sear. In that case, I recommend carefully filing a little off the foot of the disconnector to increase its overlap. |

If you're uncomfortable doing that, keep replacing hammers and disconnectors as needed, maybe triggers too; or take it to a gunsmith to perform the adjustment (filing). |
