gorilla Posted January 21 Share Posted January 21 (edited) Hi Just bought a used WE SCAR L GBBR. Has a problem with the trigger box, guessing its the standard M4 type? The problem is that it fire on auto when on single. I'm able to replace parts, but I just need to know what the issue is with the trigger box. Many thanks Edited January 21 by gorilla Mispelling Link to comment Share on other sites More sharing options...
ButcherBill Posted January 21 Share Posted January 21 I have the WE Scar-H which had it's faults from cack handed teching by a previous owner, sorry I can't help with your current issue but worst case scenario is £35 + postage for a new trigger box. I've used KYairsoft for a few times for parts without any issues. https://www.kyairsoft.com/scar-93-gbbr.html Nick G 1 Link to comment Share on other sites More sharing options...
Nick G Posted January 22 Share Posted January 22 Firing full auto when on semi will be wear in the trigger parts. So either a replacement trigger box or the internals should fix it. As ButcherBill said , KYairsoft are good for WE parts, I use them regularly for bits . Link to comment Share on other sites More sharing options...
EvilMonkee Posted January 23 Share Posted January 23 Sadly WE internals are made of cheese and need replacing. I suggest the RA-Tech steel parts rather than buying the WE parts just to have them wear out again. As the guys have said KYAirsoft should be able to help or RA-Tech website Link to comment Share on other sites More sharing options...

As the guys have said KYAirsoft should be able to help or RA-Tech website Expand That's not my experience . Both my L119's have had many thousands of rounds through them as has the L85. G3 and MP5 are relativly recent additions, but I've never had a compnant in the trigger box's fail. A mate did when some numpty forced his 119 into safe without cocking it first, so that was user error. I have had way more issues with RATech parts than with the stock WE ones tbh. Same with my pistols, never had to replace parts due failure ( except the HiPower valve knocker which is fragile) despite some very hard use .

Ran the L119 A1 last Sunday untill the cold got to me and I called it a day. Gun ran flawlesley.

RATech shit just causes more problems than it solves. Not upgrades, just overtly expensive side grades. I have had stock WE trigger boxes last in excess of 100k bb's, but it requires proper regular maintenance. Nick G 1 Link to comment Share on other sites More sharing options...

Expand Do you mean the crenalations at the front that fit into the back of the hop unit ? If so , losing most of those wont stop the gun from working properly . Possibly losing all of them wont actually cause an issue. One of mine is missing a pretty substantial section after I got heavy handed sorting out a broken up BB that got wedged in there after a miss feed .

Expand They broke off & affected the performance at the time, enough to be relegated to the boot of my car, on closer investigation I found the issue & replaced it, the lugs are cosmetic but it was only £30 inc postage to replace it. I've kept it as spare parts as it fits my Scar-H too. Nick G 1 Link to comment Share on other sites More sharing options...

Nick G Posted February 13 Share Posted February 13 Its a while since I had a mates SCAR apart , but I think that looks right. I'd suggest taking the selector out and flipping it end over end and try re installing . See if that does it. Link to comment Share on other sites More sharing options...
