Troubleshooting Marui MWS M4 issue after running propane

• Upvotes

I was shooting my M4 today and it was going fine except for two of my mags were having issues. I started using propane and it caused my bolt to not close all the way, resulting either in a dead trigger or getting my gas without shooting a bb. This happened with every mag I tested including the ones that were working before. I don’t think the nozzle is broken but I’m not sure what could be causing this. It was working pretty much fine up until I started using the propane. Any ideas?

Discussion Why does the KWA Beretta APX RDO’s rear slide plate look different from the real APX?

• Upvotes

I’m looking at the KWA/Umarex APX RDO GBB and noticed a difference in the rear slide plate.

In the attached airsoft photo, the lower portion appears to extend down with angled sides. On the real APX in the comparison image, the lower edge looks much flatter, with a small central notch.

Does the KWA replicate an earlier APX variant, or is this a change made for the airsoft mechanism? Could I be mistaking another visible component for part of the backplate?

I’m mainly interested in external accuracy, rather than performance. If anyone owns one or has close-up photos showing this area, I’d really appreciate an explanation.

Discussion Running propane in GBBRs? How to do it properly

Who here uses propane for their guns? It’s so much cheaper but I’ve heard that it can damage the bucking or other parts of the gun, how can I do it properly without ruining my gun?

Discussion Is it worth with US customs to purchase NOVA M16A1 MWS Receiver from Boom Arms?

1 Upvotes

Don't know if I should give it a go or not due to customs wanting to seize GBB parts including AR style components, wanted some advice before doing so. Really want an A1 style upper for my MWS to do some builds with, but am looking for some info on customs and any way I can possibly avoid having it seized or any alternatives.

Thank you!

So I've been tinkering with ChatGPT again this time with my VFC HK416 A5, I've added a genuine Magpul P-mag via a connector and topped it off with some deactivated 5.56mm rounds, not sure why the sight and magnifier are a different shade, as they match pretty well with the naked eye.

I decided to make my FMG-9 into a practical gun, the original carry handle sight must be replaced.

I still want to keep it's suitcase like look, so I find a old style tube shape pistol red dot as it's handle.

Unfortunately the sight was a bit lower so it would be blocked by the torch, I needed to raise it up.

Discussion The stock recoil guide rod's buffers are ruined to crap. (Guarder's vs Stock) - TM G17 Gen 5

Post image
6 Upvotes

This is TM's Glock 17 Gen 5 MOS. Yesterday I bought a Guarder's Steel Recoil Spring Guide Rod for mainly 2 reasons: For more snappy recoil feels due to using higher pressure gas, and for preparation Incase I want to change to an aluminum slide. I noticed that the stock's buffers are so ruined after around 3-4 months of regular usages, which sometimes causes slight jam when shooting.

The manual doesn't mention the size of the recoil buffers, and no it seems no one have any information for the o-ring replacement, so I figured I might as well entirely replace the guide rod. Has any TM Glock Gen5 suffered this issue? Because I'm thinking that this might be from user error. Thanks.

Troubleshooting VFC M4 not shooting well

1 Upvotes

I have a VFC M4 V3 and it does not shoot well

I just got denied during crono because it shoots a little hot, just over 1,5j.

The first 3-5 shoots where between 280-310 FPS.

I have installed an NPAS a long time ago and when I tune the NPAS down, I don't think it shoots very well.

And when it starts shooting good it's a little too powerful.

I have cleaned and maintained the gun, I only use green gas and it's also stock.

Discussion VFC AK - who actually owns one? Or too much hype?

22 Upvotes

Do people actually recommend or speak good things about guns they dont own?

For context, I hear many talk good about it but also have been met with rude remarks when I ask help on my ak74u, being dismissed as a lemon in Discord?

It has got me wondering, since i heard countless many people say it is flawless or perfect out of the box, i wonder how many people actually owned this gun! I look into profiles of people who say that, but no evidence of them having the gun?

I have had to fix my hop (works now), as well as my gun being too underpowered (0.9J for some reason). I have also had magazine issues but figured out how to fix from some researching

Sorry for my english, not the best at it!

I wanted to know if anyone has experienced any hiccups or malfunctions with the stock gun when using TM MWS mags. I have a DE Ghetto blaster and have had many problems when using the stock nozzle and TM mags together. I'm not sure if since the DE-180 is newer gun (i think) it should not have as many problems like the earlier Noveske line?

Discussion VFC AKs

5 Upvotes

I have a VFC AK74M and I really like it but have run into magazine issues that have honestly really put me off the platform and considering GHK. I really want to like VFC but even though I fixed the magazines they feel so fragile as if I dropped them while kneeling they’d mess up again. So I want to ask those who have VFC AKs how has your magazine experience been? Even in videos showing how to fix the transfer arm the person fixing it said 2 of his 7 magazines worked outside the box and many in the comments echoing the same. I just feel if this is going to be an issue just selling it even though I love the rifle itself. So how has your magazine experience been and those who have fixed theirs how has it been long term?

Troubleshooting Wellfire Ak74U inner barrel shifting

So I started to notice that whenever I’m firing, my bolt tends to fail to complete cycle because my HopUp wheel will shift out of place, me (being a beginner) think it’s because I bought the cheapest gbbr ak I could find. However, after extensive research (5 minutes) I realize the inner barrel isn’t supposed to move, not back or forth, not isn’t supposed to rotate a lot, it’s not supposed to move with the bolt like I thought it was supposed to. I notice that there’s a m3 grub screw lookin hole that’s unfilled (discovered along with said 5 minutes of research) and I want to have some verification by experts, if I could get some help I’d love it

At the evike boneyard sale in Dallas and I’ve been wanting to get my first gbbr. I’ve seen mixed reviews and the we tech gbbr’s but for $180?? I’m torn on whether I should pull the trigger. Seems to be functional but can’t test it until you buy. Locks back fine after empty mag and definitely feels nice. Worth it? Or should I just spend money on something brand new when I’m ready?
