G&G K98 (G980) testing

Chomley-Warner · 2012-09-17T09:37:39Z

I'll start putting pen to paper and build up some considered opinion in this first post, feel free to ask questions or add your own personal experience, I'll add my stuff to the first post to keep it all in one place. Build quality Well, it's pretty much a Tanaka in most respects. There were issues with a pot metal hammer but with the new steel version there shouldn't be any problems with wear. The hop adjusting system is more refined with separate adjuster and lock screw so it should be set and forget. I've had a look at the hop system and it looks much like the Tanaka out of the box but I can't work out how to change the hop rubber - this will be investigated later. The woodwork is OK but has a sprayed on lacquer so easily marked and looks obvious too. As with my old Tanaka, I'll strip this at some point and re-finish with something more durable. Metalwork is fine - usual airsoft flat black paint finish that doesn't look particularly like steel but meh. Magazine The unique thing is of course the CO2 gas charging. On the face of it it has benefits - convenient to change gas but most importantly should be usable at low temperature and be less susceptible to massive power changes as temperatures increase. In theory then, no messing about with various cans of different gas to suit the time of year. First impressions are that I'm struggling with consistency - but I did with the Tanaka as well. With a high powered magazine the power drops in the fifth loading, very low power on the sixth loading and it won't make it to the end. By combining this with the unique feature of having the 'clip' separate from the power source it brings into play a rather nice concept. Use one magazine body and five clips. You will be able to use K98 pouches - the mag stays in the gun, the clips and spare bulbs in the pouches. Once you have emptied five clips, swap out the bulb and reload the clips. Nice and easy - no discovering you have run out of gas mid-mag. So, 45 shots per bulb. I bought 30 bulbs for Â£14.30 incl.postage on ebay (I'm sure with effort they can be found cheaper) so that works out at 1p per shot. Including 0.3g ammo this works out at Â£1.60 per 100 shots - a day or even weekend's shooting so next to nothing really. There is on the market now and alternative mag (same price as CO2) that uses conventional green gas charging, should you prefer to go down that route (or use it as an alternative). Accuracy Range testing indoors at 9.5m (31 feet) was spot on - every shot of a clip of 9 within a 6inch target, seven within 4inch group, five within 2 inch group. Iron sights, no scope. Gas power and consistency Initially I had a very frustrating time with serious inconsistency and mis-firing but I took apart the bolt and reassembled and this did the trick (remember, this rifle was previously owned). The next issue was that the variety of mags are mixed up and there is no way of telling which magazine is high power or lower power. Indeed, after testing to see which was which I couldn't see what makes a mag high or low power and this remains a bit of a mystery. What I can say is that the absolute maximum power I got with one mag on the first shot or two was 426fps with a 0.34g bb (equiv 2.87J or 555fps with a 0.2g). What is clear is that the power available drops shot by shot until there is no power to expel a BB. On a low power mag you can get through six clips of 9 before becoming hopeless, on a high power mag five clips. This raises a tricky problem when defining a role as with a skirmishable low power mag the power goes from about 390fps (0.2g) to 262fps. It isn't so much a problem in WW2 games where players are trusted to be sensible but may be at an open day when absolute and unmovable power limits are enforced. See table below for example data. Now, have absolutely no idea whether the same sort of results can be found on a Tanaka - I never bothered to do the analysis before and I've never seen anyone else's results either. So, the phenomena may well be the same with Tanaka. Or it might not. The dropping in power doesn't seem to affect the shootability of the rifle though, which is fab, but if you are the sort of person that hides at the back and takes all shots at maximum possible range then it might as obviously reach drops as the power drops. Green gas mag Well, got meeself a 'conventional' gas mag today so ran some tests. The only gas I had lying around was a can of "Super Power Green Gas" that comes in a camo pattern 1100ml can. Overall results show reasonable predictability. There wasn't the even and consistent decline in power of the COÂ² as the shot-to-shot fps jumped about a bit but there was a noticeable decline as shots went on. There was a marked end to the fireable shots though and the end of the gas power was sudden. Four clips (36 shots) is all you can get out of a gas filling. At 12.5ÂºC the average over 4 clips per mag filling and three fillings with 0.2g bbs was 1.15J or 349fps, with a ma...

I am after some advice, just purchased a G980 and I would like to buy some extra magazines. It has two CO2 as standard, should I get more of these or the Green gas magazine? Any advice welcome.

Another option would be to get some more clips and stick with the mags you have. If you get in touch with G&G via the Contact page on their website, they will sell you just the plastic clips. That way, you only need one mag each of green or Co2.

Yes, this is the way I do it - use one magazine, with pre-loaded clips. Cheaper and lighter to carry too.

After reading through your comments about multiple clips being easier for you guys with a single mag, we're going to see if we can stock these clips on top of the CO2 mag that we currently sell.

Sorry to resurrect an old thread but do you know if the pot metal parts have been replaced with steel components?

Great review!!!
