Problem solved! the RA tech sear and hammer have hooks that engaged too much on SEMI. This is why i had to push the trigger forward to reset the trigger on SEMI. Qlong and I decided to sand the sear/hammer notches so it resembles the stock one from WE (90 degrees). He also modded the sear/trigger so I can use a RS B.A.D.A.S.S safety selector :)

seem o have bad luck with my WE M4 this week. looks like my trigger is stuck in the firing position and when i went to remove the trigger box my selector switch snapped. now is there any Canadian retailers that sell the parts already check the ones i know in the GTA but they don't have it so i was wondering if anyone else new on that might have the parts. and is airsoftbuddy shipping reliable?

go to toronto airsoft.. he has spare parts, i saw he had a spare selector switch when i was there last week.

he was the first one i went to didn't see one there.

Email AirsoftBuddy. They will have replacement parts.

i they have them already check them out. just want to know if they are reliable or not since i have never dealt with airsoftbuddy before

Airsoftbuddy is fine to deal with.

WE SCAR magazine screw
 

I need the specifications (thread pitch, size) of the flat head screw that goes on top of the magazine that secures the feed lips. WETTI has been of no help to me. :mad: I have posted this on several other forums and no one has any clue.

Any help is appreciated!

thanks coach looks like i'll do this thursday

So here is an interesting problem I have just installed a ra-tech CNC steel hammer. After reassembling the trig pack and reinstalling that into the lower receiver, I did a test fire the first few shots were fine. Shortly after I would fire once in semi (the magazine is set to enable dry firing) and the hammer wouldn't strike. So I opened the gun up and the hammer was reset and looked like it was ready to fire. I then put te gun on safe and I heard a click. I decided to pull the trigger and the hammer engaged. Now here is an even weirder part. The hammer engages everytime i rack the charging handl, but when I pull the trigger with a magazine in it will shoot once on semi, and then the hammer won't engage a second time, unless I put it on safe first and then back to semi. It works fine on auto. If this was answered then I apologize and will delete my post.

hey ballcancer, guess what, I think you have the same problem as me and this other guy (madlz) who just posted a few weeks ago..Did u get the complete RA tech trigger set? or just a RA tech steel hammer? let me guess, on semi, u fire once and the trigger is locked right? and u have to either A) switch to safe and switch back to semi, or B) rack the handle right? try this. try pushing the trigger forward after u fire once on semi. When I do this, i can fire again.

If thats the case, its because the sear isnt letting go of the hammer. Ra-tech has hooks on the hammer and the sear which engages more than the stock hammer/sear. As Qlong and I (ok fine, Qlong) have established, the ra tech trigger springs are very weak.. try using the stock trigger springs instead, it should create more tension and release the hammer so that it is ready to strike the knocker valve again. If you have anymore questions feel free to PM me. Qlong, if ure reading this, feel free to jump in, since ure more knowledgable than me (*bows down humbly at your feet*)

just installed ra tech inner barrel 250mm and ra tech stinger kit.. fps increased dramatically... 400-410fps with no hop up using 0.30g madbull bb's...

PVC Block Mod pics for Ross... has so far avoided any hingeplate destruction while this lower receiver was installed, no such luck while borrowing a friend's lower.

awesome, thank you. So the bolt catch still works, I guess the only downside is less recoil? And does the bolt actually travel all the way and actually hit part 66? Or does it just get close?
