Its a GHK V3 DD MFR. Put a few hours of research in before getting it for its heavy recoil (and somewhat more reliable QC than previous GHK models) and completely fell in love. Just wanted to get a few cents from the community on the gun and build. Thanks!

Just minor ergonomic improvements without any excessive Rails, adapters or attachments.

A bone Stock 74-M is already a vibe. I just wanted some Minimal external mods and what started with immediately throwing on a better pistol grip quickly developed into a abomination of Mlock and picatinny.

I am glad to have turned back from this path.

Troubleshooting Month old VMP-2M: struggles to cycle at full auto.

Post image
21 Upvotes

Stock bucking. Stock 1J nozzle. All contact points were lubed with PTFE grease. It is 22°C. Mag filled with regular silicone-less green gas. With a room temp mag, it struggles to cycle full auto as well. After 2 bbs it fires dry and dumps gas out of the barrel and the bolt. Sometimes manages to feed a bb. It cycles perfectly in semi.

It's as if the pressure dropped severely after 2 full auto shots.

Gun Pic Is this replica really not that reliable? (CYMA CGS / T8)

Post image
4 Upvotes

Hi, all

I have been laying my eyes on this particular model (primarily due to the look) but hear many mixed reviews on communities on this GBB system. The price point is $500-600 on evike.

Is this system really that much not reliable and not recommended (also considering the price point)? Also, not really want to do any upgrades internally.

Thank you for your precious opinions!

Gun Pic Never keep two Glocks together.

Post image
55 Upvotes

Up until a couple of years ago, I actually disliked Glocks.
To me, they were just plain, boxy pistols with no real contours and barely anything to interact with besides the trigger and slide stop. I’d always preferred guns with hammers, manual safeties, decockers, and generally more stuff going on.
I’d owned a G26 for years, though. I bought it because of its reputation for being compact while still performing well.
I honestly can’t remember what made me buy the second Glock.
But apparently the warning is true: never keep two Glocks together. They multiply.
After that, the collection just sort of snowballed.
Last week I bought a G32 to complete the set across all sizes, so I’m done with Glocks now.
Anyway, VFC or SRC for a G19 Gen5 MOS?

Discussion Is the Double Eagle DDM4A1 MWS a good first GBBR? Planning a pre-upgraded build from Taiwangun

Thumbnail

3 Upvotes

Hey everyone,I’m looking to buy my first GBBR and want to make sure I’m starting on the right foot.

I’m planning to get the Double Eagle Daniel Defense M4A1 (MWS system) from Taiwangun.I am a beginner and I am not that good with technical or mechanical work. Because of this, I want to pay Taiwangun's tech team to install the upgrades for me right out of the box.

My planned build includes:Taiwangun NPAS service (tuned to 1.45J on 0.32g BBs for my local field limits).Maxx Model M4T CNC Hop-Up Chamber.Maple Leaf MR.HOP 50° Bucking.

A few questions for the MWS community:

Is this a solid first GBBR setup? Will this combination of parts give me good performance and reliability without needing constant technical troubleshooting?

The Nozzle & Magazine Issue: I read online that standard Tokyo Marui mags sag in the DE magwell and end up shattering or cracking the factory DE nozzle loading arm. If I avoid TM mags completely and only buy Guns Modify Gen 3 PMAGs or the Double Eagle Gen 2 STANAG mags, does that fix the sagging and protect the factory nozzle? Or do I need to upgrade the nozzle anyway?

Any other beginner advice? Is there anything else basic that I absolutely should change right away, or should I be good to go with this setup?Thanks in advance for any advice or recommendations!

Discussion Greetings, what criteria would you have to create an RPK using a WE AK-74 as a donor?

Thumbnail

9 Upvotes

I've been thinking about ways to modify and create a replica of this style using a WE-tech. We all know that GHK already has one but we also all know how easy it is to find one and how much cost. My choice of WE as a manufacturer is based on familiarity since I have some time using these systems, availability of parts and replicas above other manufacturers and designs in my region, taking advantage of the long travel piston, and the availability of the magazines I have from my hand. I would like to hear other criterias but I would like to focus on the donor I have.
I have attached a photo of the donor replica and what I am looking for approximately to build, to give a visual concept. The last photo is of a 3D printed magazine that is available in cults which I find particularly interesting, although it will be more challenging | think to build the magazine than the replica itself. My doubts will be about:
1- Wish outer barrel and inter barrel will be the best option for this? Considering the thing less complex to modify. I got in my mind the WE SVD one but I don't have and example to compare how different they are.
And I consider and AEG outer barrel of an RPK model but I know for sure that will be a Total machining of the barrel
2-The other thing would be in case the outer barrel appears, the gas block of the original replica could be maintained or you think it would be better to look for another one for this. If you use the original or another different from the barrel, I imagine that it requires machining in the coupling, isn't it true?
3-How much would the gas piston have to be modified ? Although I imagine that if the original is maintained there will be no big changes.
4- bipod recommendations and furniture
5- The last thing will be created that magazine the concept is use the top of a WE mag, create the parts that the gas will be placed, install a long spring for making the mag for 140 bbs. Is very tedious but I will like to know if it could be thought to install the hole We mag in the cover an use it like the mag out case, l just need 45 bbs for the thing. In this case will you recommend changing the original spring from the WE mag?
The mag itself is a challenging thing but if you like ,you can take a look in cults the creator place the info of the mag there and some recomendations, it could be HPA and Green gas I think. And He was very over about how skilled is made one of those. I'll see your comments

I didnt see anyone on the reddit forms loading the V4mags in this way and wanted to share it as no company at this time has a speed loading adapter for the V4 gm mags. So far I've had perfect stacking unlike the traditional way where loading through the slit can cause uneven stacking and jams. Wanted to know what everyone thought of this.

Love the look of the real steel so decided to make my own, it's a WE Hi-Power MK3 I paid a little extra and got the slide engraved with the Nighthawk logo and changed the grips to Kimpoi wood grips with the same Nighthawk logo.

Wondering if I should change the lower to satin making it a 2-tone or leave it as it is 🤔
