The GBBR Thread

As with AEGs, barrels have little to do with accuracy. It's all about BBs, hopup rubbers, hopup units - in this order. Just see an old TM MK23 with the aluminum barrel.

Surely the order is hop rubber, hop unit and then ammo? Lol.

Tbh it could be argued the unit is more important than the rubber, BB is definitely the least important though.

Though if we play Devil's advocate, the best thing you can do for accuracy is improve your shot to shot fps consistency so that it's nigh on exactly the same each time, as consistency in power will help significantly with the repeatability of your shot placement.
Unfortunately, using gas as a propellant, especially in a gas blowback platform, makes that level of consistency impossible, even with HPA set-ups =[

 
The very best thing you can do with a G5 is leave it alone, they need nothing out of the box, you will spend needless money that can be better spent elsewhere
Sure I saw a deal for the G5 with 4 mags, gasand lube in AI mag, around £385 iirc (think it was Pro Airsoft Supplies but may be wrong).

 
Be careful with the nozzle as they have a tendency to break at the loading nub when the magazines you're using are new.

If you fully load the magazines the pressure from the magazine spring can press against the nozzle so hard that it snaps off the bit that loads shots into the hop unit. So you can either short load the mags for a bit, or the easiest thing to do is just lock the bolt back manually before inserting the mag.

Once the mags have had a couple of hundred shots through them the springs ought to relax enough to not run as high a risk of damaging the nozzle but it's still worth being aware of.
Cheers for that Ed, I wasn't aware of that one. So you're saying lock the bolt back before inserting the first mag, then bolt release catch to close the bolt. Then each mag change should be ok because the bolt will be locked back when the mags empty?

Correct :)

A link would earn you a forum high-five, though you know what they say about things that are too good to be true...

If after GHK guns then Samoon are well worth checking out. Fantastc service, free bits and they understand our customs/VAT rules. Fast shipping too and probs cheapest G5 mags you'll find if buying in pairs!
Samoon is effectively the GHK factory shop - and others have said, great service.

I think this may well be what happened to my WE P228. I had been filling the mags really well, so perhaps i can do those things with my pistol as well

 
I see, will an NPAS fit a G5? is there a specific make or model that ill need?

found one at Milspec. Im just thinking how i will upgrade the G5 over time, is there any benefit to extending the barrel and turning the NPAS down to keep the FPS around 340? i'm not sure if i remember from somewhere that barrel length on a GBB does have a significant effect on accuracy, but i may well be mistaken :P
There's no actual NPAS for the G5 - the one Milspec sell (and I use) is just a screw thread and screw carefully drilled in to the side of the exit port to reduce gas flow. It does the job, but it's not linear in power reduction.

If you use a G5 stock you don't need one. I only had to get one as my carbine kit meant I was shooting ~370 at the height of summer on the stock nozzle (wide open the Milspec sold one would let me shoot over 400, but I was also able to crank it down to 330). BTW if you do find yourself too high then you can try a lower pressure gas - I actually used 144a (took me down from ~370 - ~300) - though I only had that on me as I was also using a Maruzen Walther PPK the same day.

I trust you, perhaps the offer was so popular they have none left now :P

 
I'm looking to get my first gbbr soon, I'm wanting to get a VFC HK417 has anyone had any experience of these?

Wouldnt surprise me, picked mag up before xmas ,noticed it was a good offer but as wasn't after one I clearly didn't pay the vendor enough attention lol. :)

not sure if this applies to HPA as the regulator will ensure the same pressure shot to shot (it will vary slightly depending on how the reg reacts to pressure change).

 
Any ghk ak owners? What are they like range fps accuracy etc ootb and are they worth the money?

In a GBB HPA will help but it's still not going to be perfectly consistent because the way the bolt and the magazines interact means that the seals are unlikely to line up the same every time, and there's a space between them, meaning there's always going to be a small difference in the amount of air being leaked through the gap between the moving parts.

In an AEG fitted with an SMP or Polarstar, or a non-blowback gas gun, be it a pistol like TM's Mk23, or a bolt action sniper, the gaps between moving parts can be either completely removed, or very well blocked off, offering much greater consistency.

The GHK AK are very much the same as the rest of the GHK family, good range and consistency out of the box, however the AK mags are quite well known for just leaking for no apparent reason, they don't have full bolt travel as the WE AK does but it's more than sufficient for airsoft purposes, by all accounts (as I haven't had the use of one yet) the new GHK M4 is very good, no issues at all
