WE GBB PDW

[mnmc10]

my open bolt/ open breech pdw shoots a good 20 feet farther than a kwa/ksc mp7 using same gas and same bb weight. ive shot kj/tk, we, wa, gnp, jg, agm, and kwa/ksc. and so far the pdw shoots the farthest.

[ahadsz]

ok so I want the open-bolt, got it, and like that doesnt help too much if it should about 40m its fine but anything else i may have to reconsider...

well yeah, but 20 ft more then what? Is it 80 ft or something lol?

[mnmc10]

well i have the room to test its max range but i cannot get an actual measurement cause the very end of the firing range is my neighbors garden. im sure he will be baffled to see me going in his garden with a measuring stick. lol

 

btw i retested the kwa mp7 against my pdw and the mp7 outshoots the pdw by 10 feet. the previous day the pdw was shooting farther. i also used the mp7 as my base cause out of all the gbbrs out there the mp7 has the best range. my mp7 shoots at 350fps while my pdw shoots at 320fps. if i can match the fps of the mp7 the pdw might outrange the pdw.

 

 

"well yeah, but 20 ft more then what? Is it 80 ft or something lol? "

 

i assumed that some of you guys already tried to shoot an mp7 and yeah cause it shoots the farthest.

 

 

update:

i tried measuring the distance using wikimapia. and i think this is almost accurate plus minus 5 feet.

OT: i have a total of 6 mags for my we m4 magazine and i wanted to buy open bolt kits for all of them. thing is airsoft buddy is out of stock for a long time now. can you guys give me other online stores where i can buy it?

Well 131 ft isnt that bad, so your saying that the kwa mp7 shouts 20 ft more, dang..lol! I may get the open-bolt version, i like it, and do you guys suggest co2 or gg for usage? and im getting it from blowbackarmory.net so here look, and what upgrades do you guys suggest?

Well with the closed version, to run CO2 properly ( as in, run without something breaking ) you need to change the trigger group to an "all steel" one. I have my WE GBBR's with the CWI's trigger group kit so i can't vouch for the RA-tech one but my M16 has now more than 5k rounds with Co2 ( and a lot more with GG ) and there hasn't been any breakages yet.

 

You would also need to mod part #117 and probably buy the reinforced nozzle but since i don't have much experience with the open bolt kit ( apart from my M14 ) i can't tell what you would need to buy/mod/do to the upper assembly so that you could run Co2 on the open bolt without worries.

Since the new nozzle is made out of plastic i wouldn't feel safe running Co2, as soon as i get an open bolt SCAR or M4 i will run Co2 through it and check how many rounds it will last until it breaks ( my bet is not a lot ) but it seems that the open bolt kit for the SCAR/M4 won't be out any time soon so until then my guess is as good as everyone else's.

 

And my suggestion is ... don't use co2 with the open bolt kit until you get some spare upper assembly parts

[ahadsz]

well yeah thats why i was thinking to get closed bolt but its having issues..darn, well any other suggestions?

[danielsilva]

Unless you need to play with it below freezing temps you won't necessarily need to use Co2, i've played with my closed bolt m4 with -5C and it functioned as it should on semi/short-bursts. The lowest temp i got to test the M14 was 1C and it functioned perfectly. So unless you play with it in extremely low temperatures ( like > -5C ) and/or REALLY don't want to loose too much ROF/recoil and thus need to use Co2 instead of GG, i suggest you to buy the open bolt and just use GG. It's safer, cheaper and equally fun.

 

I'll be really honest here, although i initially bought 5 gg mags plus 5 co2 mags and internally upgraded my GBBR's to the maximum so that i could use co2 on them, i ended up buying more GG mags and now use GG almost exclusively. Yes the recoil is awesome and it gives a healthy boost to the ROF on very low temps but it's just not worth it to me. When i REALLY need to i just get my M16 and use the external rig i made for it and use co2/hpa.

[ahadsz]

well in the winter it gets to about 28 f which is about -6c but I wont play in that I usually play in about 45 f which is like 10-15 c (during the winter) but during the summer it gets to about 80-90 f here so, yeah it gets cold and hot, I may get gg, but maybe co2 still deciding and yeah the pdw is sure a choice to consider and I will run it on GG, hopefully nothing goes wrong with it though, im looking at the we m16 and the m4 so still looking, as they say research is well done when taken time.

Just got me a WE PDW GBBR (open bolt) from AEX today.

 

At about 70 degrees, it shoots about 320 fps with 20g bbs and Duster gas.

 

I'll set the hop when I get back from work tomorrow then do some more fps readings and such. I'll also post up about the gun's range and accuracy.

 

 

Which magazine do you guys prefer? the PDW mag or the Stanag mag?

[ahadsz]

PDW if possible, oh and if you can, is it possible for you to test with GG? And can you calculate range for me wither .2's or .25' thanks snoopy!

FINALLY! Someone else in the world that owns one of these.

 

How do you find it cycles on duster? (Only have propane on me at the moment, at 20c its roughly 410FPS)

 

Personally for looks and that fact its mostly plastic (better for colder temps) the PDW mag.

The M4 has slightly more gas capacity however.

 

Finally, you may wish to file down the part in the lower left of this photo:

 

Otherwise it will rub your bolt and also take a chunk out of your nozzle eventually like so:

Reppyboyo-

 

The gun cycles very well on duster gas at 65-70 degrees. The bolt locks back every time.

 

 

Which part do I shave down to prevent the damage on the nozzle? Do I dremel the pointy part of what is engaged for full auto firing?

 

I was at AEX and inspected the units that they had at the shop so I can pick the best one. They had 3 in stock, 2 of them has that particular part of the nozzle nicked. The one I got did not have the said damage. It still doesn't.

 

----------------

 

ahadsz-

 

Sorry but I will not be running green gas in my gun.

[sacairsoftsn00py]

I'll see if I can write a review of the WE PDW/RDW Open Bolt GBBR.

 

Right now I'm trying to find out little things about it. Anyhow, took a few more photos to share...

 

Shows the trimmed part that ends up gouging the back of the gas inlet lip of the nozzle.

 

 

Where the "pointy" part that was shaved was coming in contact with:

 

 

 

Another contact point(s) that should be addressed:

 

 

 

 

 

 

Warping should be minimized by tapering off the underneath part of the charging handle. Will post photos after I modify the said area.

[ahadsz]

thats fine, thats why I asked, how about .25 gram bb's thats all i ask for, haha.

[sacairsoftsn00py]

Modified my flute valve. Actually, I just added an o-ring to drop the fps some.

 

At 75 degrees, the gun shoots 320 fps with .20g bbs and duster gas before the modification.

 

I'm preparing for cold weather. I will be running propane/green gas later on.

 

At 75 degrees, with the o-ring on the flute valve, the we pdw shoots 280s. With .25g bbs.

 

Accuracy is acceptable. At the velocity given with the weight of bb used, 150 foot shots will yield hits on person sized targets. The gun is skirmishable. Accuracy is acceptable though I must say that a tokyo marui pistol is more accurate than the we pdw open bolt gbbr.

 

That's it for now. I will keep shooting it and report my findings.

 

Max range with the current setting is in the neighborhood of 180 feet.

[mnmc10]

i also modified my rocket valve but to increase fps on 134a. i just nipped 2 of the four pillars to increase gas flow. added about 20fps!

[ahadsz]

ok..hmm maybe ill get this as a secondary up with the kjw this is sick as well 180 ft isnt too bad, and I think if we can upgrade it with some ra-tech parts and possibly bullet proof upgrades it will shoot further, ill let you guys know what one I get and how they perform hopefully soon.

[mnmc10]

how come my pdw's range is only around 130ish feet at 300 .25's? its around 33deg c here.well it goes farther but at 130feet i can still hit a tree trunk. anything beyond that im not sure cause as ive said its already inside my neighbors lawn.

[Reppyboyo]

Anyone have a vid of their OB PDW firing on 134a?

I`d like to see the performance vs green/propane.

[mnmc10]

i dont have a vid but i use 134a and it cycles well. the only difference is that on gg it has more recoil.

[sacairsoftsn00py]

More recoil and higher FPS.

 

My gun is almost back to stock configuration.

 

I replaced the solid hop "nub"/ spacer (the thing in between the adjustment arm and hop bucking) with a guarder silicone nub (off of a Guarder Clear/Soft AEG Hop bucking).

 

I will continue to do my personal performance evaluation with it and report my findings on my spare time.

[Reppyboyo]

I should be skirmishing with mine again on Sunday.

Will use 134a and report back on its performance

[sacairsoftsn00py]

Got to use the we pdw open bolt gbbr at a game today. I had cut the inner barrel down to drop the fps. I was running it with propane and .28g bbs. Range is impressive...accuracy is acceptable. I could hit a target past 180 feet. Once every 3 or 4 shots narrowly missing it by a few inches or a foot to the left, right, or up high. By target, I mean a person sized target. I wouldn't say its as good of a shooter as the kjw m4 but it is definitely skirmishable. The open bolt system offers a night and day difference compared to the awss/escort/ closed bolt system we has been using.

 

Sorry for the informal post. I'm on my phone and driving the car home.
