Hello,

I am interested in the KWA M11, I have been wanting to get a GBB for a while now but never have really got it it. Anyway, I want some personal opinions about the gun and its overall reliablity. I have heard that the bolt locking feature eventually wears and sooner or later breaks. Also, If I get a propane adaptor, how much slicon oil should be fed into it?


Thanks

First of all, KWA does not recommend using propane.  You will find the same warning in the manual.

Secondly, bolt locking is a feature of the Mac11 as a part of the function.  There has yet to be any official report on the bolt lock breaking in our model.   If any premature damage occurs (either natural or human) the product can be serviced stateside or if the customer so chooses.  Parts can be acquired through the same process.

I have the M11 NS2. Awesome weapon! Its light weight and very intimidating. The rate of fire is absolutely insane! What impressed me the most is that the gun can dump all 48 rounds in one trigger pull in the middle of winter without any cost to performance. Furthermore, there is still enough gas in the magazine to push out another 20 bbs. Keep in mind though that I let the mags warm back up to room temp before firing the remaining gas.

Accuracy is not as good as my 1911, so dont expect anything great there lol. All in all, I love my M11!

one drop of silicon per 8-10 mags

although propane will void your warrante, it will not harm your gun any more than green/duster gas.

that's not true Cake...

Propane has other crap in it that builds up on your internal parts, especially the moving arts of the GBB system. You don't get that build up with Green gas.

Actually green gas IS propane. The only difference is that GG has silicone mixed into it. Propane wont hurt your GBB anymore than GG, however, you must make sure your weapon is properly lubricated at all times. I believe this is the reason why KWA recommends only GG; basically maintenance becomes a bit easier since the seals wont dry up as fast(in comparison to running dry propane...which is a mistake as previously stated).

To my knowledge commercial propane is just a mixture of pure propane and an additive that gives a scent for leak detection. There maybe some impurities but I think they can be considered negligible. GG has the very same additive as commercial propane and the very same negligible impurities.

there is more then just silicone added to GG to make it GG... Propane has all sorts of extra chemicals inside of it, and they do cause build up on your moving parts. Look at the internals of a gun run exclusively on GG then look at one that uses propane exclusively. First thing you'll notice is the coloring of some of the metal parts of the chamber. Using Propane they turn a purpleish color where as a GG one doesn't seem to have that same change. I used GG exclusively in my KWA M226 and my friend used Propane exclusively in his 226, and I've noticed the differences. But anyway this is way off topic so I'm done.

No, green gas is really just re-bottled propane. Green gas has all the "extra chemicals" you mentioned. Basically, the manufacturers of green gas buy commercial propane, add a new scent and silicone oil, then re-bottle it. The new product gets sold at a higher price since its targeted specifically to the airsoft market. I believe the only true difference (other than the additives) is that commercial propane runs at a higher pressure. Have you noticed the false chemical formula on the side of the can? Ch2 FCF3 Ch3  this cannot exist! There are other reasons as well. Speaking of build up, I have also only used GG exclusively (until now) and all of my guns have had a greenish residue within the inner barrel. I thought this was the reason why it was called green gas LOL. Here are my references:

1.)http://www.airsoftca...read.php?t=6268
2.)http://fraginternati...is-propane-faq/
3.)http://en.wikipedia.org/wiki/Green_Gas

I saw the test data once before but I cannot find it now. I will keep looking. Anyways, you are right, its getting a bit off topic.

I can't seem to find the original tests either but the review by Arnie of Arnie's Airsoft Has a small snippet of the results from those tests. IIRC the original tests showed that a few green gas brands didn't have any lube in them in all and were just straight propane.

My field has had those green gas cans cans with green gas on the label but are actually propane in a container improper for storing propane explode at the field. Luckily it was in the back of someone's truck and there wasn't much it could damage, but it could have been a lot worse. Accident waiting to happen. Propane is stored in thick, sturdy containers for a reason.

I am an advocate of propane. Propane tanks have safety release valves unlike green gas cans.

I for one can not afford green gas. Its WAY too expensive. One small can of propane costs about an eighth of what a can of green gas costs.

Also most green gas has 2 main differences over propane. 1. Green gas has a silicon additive. 2. Green Gas does NOT have the synthetic smell added (that is what gunks up guns). However if you clean your gun properly and use silicon with propane your gun will be fine.

In fact after a year or two of use, all the money you saved using propane over green gas (assuming you actually use your pistol a lot) you could just buy yourself a new pistol. Posted Image
