Ian24 Posted May 26, 2010 Report Share Posted May 26, 2010 My SCAR just arrived with a hideous flashhider on it. For now it will stay in the box until I can finish my hop up project... Quote Link to post Share on other sites
danielsilva Posted May 26, 2010 Report Share Posted May 26, 2010 Noticed a little something with my SCAR - a bit of a niggle, really. The bolt lock doesn't seem to activate unless you lean the gun over to the right slightly? The catch sometimes won't lock back on an empty mag unless you do this. If you dry-fire on an empty mag, sometimes it'll catch, sometimes it won't. A few times, the rifle has been leaned over to the left with the bolt locked to the rear, and the bolt catch activates on its own. It's almost like a spring isn't strong enough somewhere in the bolt catch mech. Any ideas? Ben. That's just very weird .... Have you inspected the BCG to see if the wear on the part where the bolt stop touches the BSG is more worn on either sides ? Quote Link to post Share on other sites
Break100 Posted May 27, 2010 Report Share Posted May 27, 2010 @L4byr1nth: take off the upper receiver and you only hold the lower receiver, put in the empty mag in it. See whether part#157 touch the bolt lock properly. if not, then i believe that should be the issue. The easiest way to fix it was I putted on the bolt lock where the part 157 touch it a small steel glue (epoxy) and leave it for 24 hours. Mine worked perfectly.

L4byr1nth Posted May 30, 2010 Report Share Posted May 30, 2010 (edited) This gets weirder. I've still not found the problem. Usually, you rack the bolt, and either it won't lock, or it'll sort of 'half lock'. This is when the bolt is locked back, but if you eject the mag it'll slam forward again. You can see, if you look at the bolt lock, that it's not fully engaged. Weird thing is, though, if you push the mag up into the magwell while you rack the bolt, it seems to lock back fine. You can eject the magazine, and do whatever, and the bolt will stay locked back. Do you think it's the mag, or the bolt lock? Ben. EDIT:: Taken some pictures to show what I mean. First is the bolt fully locked - to get it to do this, I actually have to push it in with my thumb. Second is the bolt 'half locked', as I described earlier. I had to hold the bolt back with my hand to stop it slamming forward randomly on its own when you jiggle the receiver slightly, or try and press the mag release. Any ideas people?

Tutorials with pictures will win you cyber cookies. Ahhh now i get your problem, that thing ( or at least very similar ) happens on my M4 most of the times because the part on the BCG that engages/slams against the bolt stop is worn out and doesn't grip correctly the bolt stop, when that happens it's only necessary a little nudge for the BCG to slip from the bolt stop. If you inspected the bolt stop already and didn't found anything, try inspecting you bolt carrier and check where it slams against the bolt stop if it's worn out/rounded. If it is just file back to straight angles and the problem should correct itself. Quote Link to post Share on other sites
L4byr1nth Posted May 30, 2010 Report Share Posted May 30, 2010 Where is this on the gun - can you take pictures please? I've had the lower off, but I can't really see what you mean. Ben. Quote Link to post Share on other sites

Can't help you there since i don't own a SCAR ( and never will ). On the M4/M16 it's here: On the SCAR i believe it would be here, the wear would probably be where the green arrow points. Someone with a SCAR should confirm it. Quote Link to post Share on other sites
L4byr1nth Posted May 30, 2010 Report Share Posted May 30, 2010 So there should be a slot that the bolt lock hooks into? Weird it's on the front of the bolt. I'll take a look. What should I do with it - file it down, or build it up? Ben. Quote Link to post Share on other sites

Just check if it's worn down, it should be very obvious if it really is worn down and if it really is worn just file it a bit, just enough for it to have straight angles again.

L4byr1nth Posted May 31, 2010 Report Share Posted May 31, 2010 Ok, so I took some pictures while I was inspecting the bolt carrier. It does look a little worn, as you can see. Not massively, just the corners seem to have rounded off? I was going to get the Bomber CNC lightweight bolt, so I might not bother messing around with this? Could this definitely be the problem? Ben. EDIT:: Also, how come you'd never get a SCAR? Quote Link to post Share on other sites
L4byr1nth Posted May 31, 2010 Report Share Posted May 31, 2010 Also, forgot to ask last night. If I buy the RA Tech NPAS with stainless steel rod, do I still need to take that small white plastic piece off my original nozzle assembly? Ben. Quote Link to post Share on other sites
L4byr1nth Posted June 1, 2010 Report Share Posted June 1, 2010 I think the problem may be the bolt catch assembly. As you can see in the pictures above, there is a bit of up and down play in the notch where the bolt catch assembly sits in the lower receiver. As an experiment, I fired the SCAR a few times. No lock back at all. I then jiggled the bolt catch up and down a bit (while the gun was still assembled). Now it locks back on its first or second shot. Ben. Quote Link to post Share on other sites
charlie-one-bravo Posted June 1, 2010 Report Share Posted June 1, 2010 (edited) HI All, l love this tread & been following it for ages but now need to add to it. Iam a milsim player and have owned 7 WE GBB rifles, and still own & play with 3 of them all running on green gas & Co2. As we know all GBBs have issues of some kind & WE are not without theirs s, & keep bringing out new models & appear to be unable to resolve or learn lessons from their earlier models. When I have contacted WE in the past, their responce aways seems to be take it back to the supplier, this si not customer service. o I have had no end of head aches over the years with WE, but has it put me off......in all honestly NO.... why I hear you ask, well just love the whole milsum thing & GBB just add to that, Ive been gaming/ playing with my SCAR simce last November & never had a issue except for my trigger unit which gave out after about 2 weeks & my hinge plate, I did my own little tweek & fingers cross have never had it let me down since (same cant be said for the mags, but appear to have more luck with the Co2 ones). As per the real thing, they work better when looked after Have now recieved my PDW & will let you know how I get on Edited June 1, 2010 by charlie-one-bravo Quote Link to post Share on other sites
L4byr1nth Posted June 1, 2010 Report Share Posted June 1, 2010 Ok, so there appears to be two seperate problems with the SCAR. The bolt catch not engaging when you fire it seems to be fixed by jiggling it about with your thumb. The bolt catch not engaging when you insert an empty mag and rack the bolt is different. It seems that, on mine, the magazine has significant play in the magwell (up and down). On taking the lower off and inserting the mag, you can see that the bolt catch assembly isn't engaged properly by the nub on the mag until you push the magazine up with your hand. I think this is what's causing the bolt lock problems - the magazine; more specifically, the fit of the magazine in the receiver. I might use that old Tanaka trick of epoxying small pieces of coke can to where the magazine engages the magazine release. Ben. Quote Link to post Share on other sites

Andehpandeh Posted June 15, 2010 Report Share Posted June 15, 2010 Here we go! I've been unable to figure out why my scar craps out on auto, as it locks the hammer but doesn't release again. Have a video to show it: PS! The problem might be quite obvious, as I'm no technical genious, by far. Quote Link to post Share on other sites
Mad-Larkin Posted June 18, 2010 Report Share Posted June 18, 2010 Hey guys, i managed to get one of these a couple of weeks ago. Used it once and had a few problems. first of all, the bolt seemed to be sliding all the way back on firing, but only 3/4 of the way forwards. Some lube fixed this but i was getting a lot into the hop and meant hop was all over the place. How much should i be applying? and where to exactly? No matter where i set the hop, i'd get a few up, a few down, a couple perfect and then all over the place. Just seemed random. I have looked down the barrel and tried to set the hop and it doesn't seem to move at all, ideas? Biggest problem was half way through a game the bolt stopped going all the way back. It turns out that the valve guide rod (part 59) had come unscrewed, turned all the way around and wedged itself in the back. It's slightly bent unfortunately, and this was the rod that came with the NPAS kit. I have the stock rod, however the stock one doesn't seem to screw into the npas nozzle so well, are they interchangable? And if not, where can i get a new ra tech npas rod? thanks Quote Link to post Share on other sites
L4byr1nth Posted June 19, 2010 Report Share Posted June 19, 2010 Tactical Quartermaster for the parts. Loctite so it doesn't happen again! The HOP needs around 10 - 15 magazines through it to stabilise. Ben. Quote Link to post Share on other sites
Mad-Larkin Posted June 19, 2010 Report Share Posted June 19, 2010 been checking TQ, just wasn't sure if the stock one is the same as the RA-tech one. it is a second hand rifle so thought it'd already be bedded in. Finally stripped it all the way down tho, checked the hop rubber and it's missing a small chunk out of the side. Don't think it'd affect it that much, but a new rubber is on the list of parts to get Quote Link to post Share on other sites
L4byr1nth Posted June 19, 2010 Report Share Posted June 19, 2010 I'd go for the RA Tech Stinger HOP upgrade if I were you. It's pretty cheap, and apparently quite good over the stock HOP. You didn't, by any chance, buy that WE SCAR on Zero One, did you? Ben. Quote Link to post Share on other sites
L4byr1nth Posted June 19, 2010 Report Share Posted June 19, 2010 EDIT:: I meant Zero In. Ben. Quote Link to post Share on other sites
Andehpandeh Posted June 20, 2010 Report Share Posted June 20, 2010 I've been playing around with an idea.... would it be feasible to glue the mags shut to prevent leaking? Quote Link to post Share on other sites
Mad-Larkin Posted June 20, 2010 Report Share Posted June 20, 2010 Yeah i did. any reason u ask that? and i was thinking of going for the stinger one, does seem well cheap, and well it can't be worse than the stock one lol as for glueing mags, not a clue about the scar mags, but i have a mate who seals some pistol mags that he's given up trying to fix the seals on. Couldn't tell you want stuff he uses exactly, i know for the one leaky mag i got i may be going this way as well. Quote Link to post Share on other sites
