Okay guys,
A short thoughts of this one, The GBBR itself is very light weight, Nice kick when it being fired, The Mags fits nice and snug in the mag well, Now the mags being Green Gas and everybody knows the basic problems with them, to early in game to yes or no on them since all three magazines I have are working as they suppose too. I did try convert an C02 mag , well lets just say it's etremely hard to load the BB's as they are with the open bolt mags does also. I will be chrono the GBBR tomorrow let you guys know the results.

I think jamie jus got a chub haha

with .30 BBs about 356, 360, 364 FPS

with .25 BBs about 371, 374, 377 FPS

sorry for the delay had to work something out , very nice hope to run a team on gas soon

Oh yes, indeed, I just need to oker the selector switch for the other GBBR I will be ready to go, I have 9 mags that should be here next coming week for an total of 12 mags

Had the first failure today, I want to say about 750 rounds through it, Apparently the charging handle got hard to pull back and would not retract. Open up upper reciever and found the rubber boot lay over, correct rubber boot and GBBR back to working normal. Pictures to follow

After running the GBBR for five games on 5/14/2011 found the worst part of the GBBR is that BBs are finding thier way bay back behind the nozzle and jamming the Hammer and auto shear causing the gun to failed, Luckly not having to dismantle the lower reciever down to parade rest. I have roughly put 1200 BBs thru the GBBR

I am keeping an running tab on failures to assist others who may want to buy and invest into an GBBR .

These are the subject of the failures show in the picture.

Just bought my second WE PDW GBBR good price 215 bucks

The New PDW came today, found out it didn't have the improved NPAS Nozzle and housing, then I was testing the PDW and went too switch over to full auto and the selector switch broke, which guess I should look at it litttle better.

Pictures will be up tomorrow

lol at least it hasn't eaten parts i swear my saw ate the hop-up nub before we started last time at wilcox

already went through the first Nozzle and housing and working on the second one.

The Selector switch should be here before Saturday thanks to Blowback Armory assistance

is it the same as m4 or scar , i have one if you need it

I believe so,

will have it with me sat. just in case ,

Thank you

for whatever reason it may be, the Bolt release is causing the Nozzle housing to get damage, now looking at what I can do to correct this small problem.

Try an AEG?

Love the realism of GBBR's

Love the reliability of AEG's?

lol - I'm glad you're doing this. Let me know how much it costs to get a GBB reliably working for one day, and I'll start saving.

yeah trying to document all the errors so may somebody else can gain when it comes to this model

Now the Black WE PDW ready for action this weekend, part came in and install it already and tested, go to go, Thanks Allout for standing by with the spare selector

Didn't notice, but the Hop up was damaged, was able to replace it and now it's good to go, Will post pictures of it soon.

Now this Hop up is quite simple to overhaul, Once disassemble from the rest of the Assembly, There is only an small Phillips screw holding this together, but make sure you remove the Hop up adjustment., Replace the rubber Boot, make sure you place the rubber nub correctly when reassemble the unit as it goes side ways and not up and down. there are grooves on both side of the barrel to ensure it lines up correct., once the two halfs are back to gather, you have to lift up the medal bar when inserting the Hop up adjustment back in.
