Did a search but couldn't find anything related to the issue I'm having
Recently acquired a WE Scar L. Went to zero my scope in today and... Well let's say it didn't go well.
Out of a 30 round mag, 3 BBs hit the target. The rest casually rolled out of the barrel. ?
The action cycles as it should. The nozzle isn't broken. The magazine shows no broken parts ect.
Any ideas? preferably before this thing ends up in a river ?
Had this issue on a number of WE GBBR's. Its either one of 4 things listed below in likleyhood of the cause.
1. Wear on the nozzle. Even if its only minor by a fraction of a millimeter on either the outlet or the pusher It may be so slight as to be unnoticeable.
This will cause the bolt to cycle but not load the chamber correctly. Buy a replacement nozzle as they're cheap as chips! Clean any crap out of the bolt assembly and make sure the nozzle return spring is in perfect condition and nothing but. If its deformed in anyway it will cause the nozzle to stick in the hop unit. Make sure it's not running a npas which has been opened or closed all of the way as well.
2. Hop up assembly.. Not just the rubber.
The scar assembly isn't to bad but if its been put back together incorrectly then you will have little pressure holding the BBs in and a poor air seal. If you look at the main housing which is a made up of 2 grey parts held together by tiny Phillips screws you will see what I mean. Take it all apart and make sure your hop rubber is in good condition and straight, with the contact patch properly alligned with the window in the barrel. Wrap a tiny slither of PTFE tape on the trailing edge of the rubber where it meets the barrel. On reassembly make sure the screws on the housing tighten up fully and you get a flush fitting between he 2 housing parts. If them screws don't tighten then someone's stripped the threads which is so common its unbelievable. There should be no gaps in the housing what so ever once its put back together. additionally if them screws have been replaced with longer threads you get the opposite problem where they tighten up and actualy push the housing apart. Make sure its flush!
3. Hop up assembly alignment on top receiver.
The outer hopup housing is held together by 4 torx screws, 2 on either side of the receiver. In the black notches infront of the ejection port. If you loosen all of these off these (tool should be included in the foresight, but don't take them out completely, just a couple of turns on each screw.) you will see that you can mover the whole barrel/hop assembly forward and backwards a fraction. Make sure its perfectly centred before tightening the screws back up. Do this whilst the bolt assembley is in the forward battery position.
4. Damaged feed lips on the magazine.
Less Likely as the we mags are pretty good. But if a feed lip is damaged it will cause BB'S to stick as well as the nozzle to jamm. Replicating the issue with differant mags will prove/disprove the issue.
I Hope this helps, I've had a lot of experiance with WE scars over the last 10 years since the closed bolt version so I can almost guarantee it will be one of the first 3 areas I've listed.
Edit* Also don't assume you've just got one issue. BBs rolling out of the barrel are normally an issue with he hopup, BBs not loading are generally an issue with the nozzle.
