We gbbr

[Funker-Tactical]

my we pdw is comparable to my tm m14 actually and it is heavily modified. i found the we pdw shoots very far and to be very accurate i just run it iron sights

I really don't like the idea of mags being consumable, especially at $40 each.

With hop up and tightbore upgrades, you should be able to have comparable range to your TM M14. However, consistency is gonna be worse on GBBR's due to both recoil and bigger velocity deviation between shots.

As for reliability of WE's GBBRs, I can't say much because I've never owned a GBBR from them. However, from personal GBBR experiences, it can be reliable as long as you take care of it. GBBRs do require a lot more maintenance than AEGs. That being said, maintaining a GBBR is very straight-forward compared to AEGs and when something does fail, it is extremely easy to replace.

I think the biggest disadvantage for GBBRs is cold weather. It really does kill the performance and gas efficiency. So if you game outdoor during winter, consider an AEG backup.

Has anyone tried using those thermal bags to keep mags in with a chemical warmer during breaks or reloading time? I would think the mags would warm up pretty quickly in those bags, but haven't tested it myself yet.

Although, AEGs for winter is still a better bet, unless your indoors.

I've tried hand/foot warmers, it helps, but only for a short time.

But have you tried it in a thermal or insulated bag?

The mags cool down from the inside... unless you have a way to keep the mags at a warm temperature .. warming them will only help for the first few shots.

GBBR suffer significant performance degradation under 10 degrees c .. if you are gassing with propane

You essentially need a secondary chamber. Which I believe the p90 will have

Reliability goes....
Open Chamber, are we talking 0-10k rounds, or 10k+ (by round I mean number of times it was cycle, either manual or gas)

Generally speaking, I like to place WE AR-15 Open Chamber in two categories,
1) Regular -Stock WE
2) Premium -RA-Tech Custom

As far as my experience goes (some from G39 series)
The parts that will break are...

• Firing Mechanism at about 10k (hammer, trigger, disconnector, firing pin, firing pin delayer)
• Bolt Carrier at about ~30k (speeds up approximately 2-4 times if you're running steel firing mechanism
• Nozzle no round count (constant double feed/ misfeed

There are some mods STRONGLY suggested to apply regardless whether its Stock or RA-Tech

1. Shim the bolt catch w/ 1.5mm gearbox shim (helps prevent wear on bolt carrier, bolt catch and making sure it lock back on empty)
2. Tighten all screws in lower receiver (don't strip screws but generally they're rather loose)
3. Tighten the delta ring, (found them to be too loose causing wobble on handguard)
4. Lube up the gun, avoid using silicon oil on parts other than nozzle and magazine. (I use gun oil for firing mechanism, bolt catch, magazine release, charging handle latch, and bolt carrier where it contacts firing mechanism)

Rules about GBBR
-NEVER EVER EVER USE FORWARD ASSIST, if you have a bb misfeed and you use forward assist hard you can break your nozzle
-Treat all jam as double feed in ar-15 (lock your bolt to rear, remove magazine, clear obstruction, then cycle it)
-If bolt carrier cycles weirdly when it supposed to lock back, check to see how much side to side play is there on bolt catch (shim it if there is) If you don't fix it, you risk breaking bolt carrier or bolt catch
-Clean your gun if you use anything other than duster gas, Propane and Propylene are really dirty

What I like about Open-Chamber over AWSS:
-> More realistic in looks and function (crisper and higher cyclic rate)
-> VSR inner barrel and hop up (doesn't get any better)
-> Replacement part readily available, a spare set of conversion kit is essentially cover all the part that would break (some such as innerbarrel-hopup assembly are very unlikely)
-> Busted feedlips? Open Chamber mag kit is there as a mean to replace the feedlips.

I was thinking something along the lines of that. What if someone were to make a second "buffer" chamber which is temperature controlled.

@Kullwarrior,

Very good point on the misfeed/double feeding. Never ever use forward assist or rack the charging handle (with mag in) in the event of a double or misfeed. Trying to load several BBs in the chamber can easily break the loading nozzle.

I will add this to kullwarrior's great list on open bolt GBBRs:

Always keep the nozzle o-ring well lubed with silicon oil. It is imperative that the nozzle moves freely within the bolt carrier (though it is normal for nozzle to stick in the hop up chamber while the carrier pulls back until the nozzle spring works to pull it out). In my experience, 90% of all jams and misfeeds are caused because the nozzle movement can't keep up with the bolt carrier as it cycles.

Every 10 mags, I take out the bolt and add a few drops of oil on the O-ring. Then slam it back in and you're good to go for another 10 mags. It's a 20 second exercise that will save you a lot of headache.

Don't use too light of an oil. I find the oil that comes with KWA guns to be the perfect viscosity. It's a bit thicker than grenade oil.

Just wondering, right now do we know if WE is going to release an MP5? If so when? Will it be comparable quality or better quality than the VFC?

yes, no date yet, no way to know

[LocoYokoPoco]

Might wanna check this out, just released recently, but not sure if you can get it in Canada quite yet:

As soon as Christmas rolls in, I might consider retiring my KJW M4 for the KWA

[Danneichh]

I'll definitely try picking one of those KWA's up. Come on, tax time...

[Eeyore]

I have one if these on the way. It should be here in a week or two. I'm really interested is seeing what the System 7 gbbr is like.
