I have been using this gas for about a year now and it is my go to gas for Gas Blowback Rifles especially. The fact that it's quite high powered and doesn't contain silicone oil is this gasses main attribute. No lube shooting into the barrel and hop unit as with many brands of green gas. This is a very clean gas, I exclusively use this in my GHK AKM, which the gun likes a lot for the reasons stated. Lasts a long time, very nice trajectory/accuracy. This is ideal if you want the best performance and you are the kind of person like myself who is happy to maintain all the seals manually and with maintenance gas where possible. Make sure you do this however if using brut sniper as it will eventually dry out your seals if you don't. If you have the time to and know how to maintain your seals manually then this is the gas you want. Don't recommend it for plastic slide pistols as it's quite powerful and isn't suited to them. Great product!
