[ARCHIVED THREAD] - disconnector problem

Posted: 7/1/2003 12:35:42 PM EDT

Took my new Sendra to the range today. It was new unfired.
Long story short, the disconnector wont allow the trigger to reset. If I use VERY light finger pressure on the trigger it will reset.
If I flick the trigger after a shot it will reset.
I put about hundred rounds thru it and managed to get it sighted in but it was a major PITA.
Once I figured out what was happening and how to shoot it I didnt bother for accuracy but tried to just run ammo thru it to break it in but no luck. Its still a single shot.
Should I just shoot it more or should I stone the disconnect?

What about the trigger spring? If this is the same unfired safe queen you described in the other thread, could the spring be defective/"sprung"?

I am having a similar problem with a reduced power trigger spring at present.

I dont think the TS is at fault. Maybe the disconnect spring?
On my other AR's the trigger will reset no matter how slow I release it so the spring plays no part in the reset as long as it pulls the trigger all the way forward.
I just function checked the gun 'till my arms got tired and it started to get much better. Actually resetting about %50. I think it will fix itself with a few hundred more rounds and or some more manual cycling to break in the disconnector/hammer engagement.

Sendra was well know for using some pretty shoddy parts. It is cool as the gun is for sure preban and there is most likely nothing wrong with the receiver specs and Nesard made thousand of them, but the guts may be crappy.

I have worked on lots of Sendra machineguns over the years that had problems.

Save your self a lot of grief and get a hold of a fire control set from Pete in NH, Bushy or any of the reputable parts guys and just replace the fire control parts and you will solve your problem for about $30-$40 bucks in about 10 minutes.

I could help you out on parts but most of my stuff is full auto parts.

Thanks Denny. I have a couple lower parts kits and various fire control spares I can try. I watched TV last night while function checking the rifle over and over to see if loosened up and it resets 90% of the time now.
The lower parts dont look too shoddy at first glance. At least they dont look as cheap as some Ive seen.
If I feel motivated today I'll swap them out.
Oh, and I noticed that under certain light the lower is an odd purple color. WTF?
