    "First GBBR, and I really wanted to give this gun a chance. I heard it was a gun that needed tinkering, and was up to the challenge, so was excited when it came to the door. At first it shot great, so I got more mags; I was probably putting about 60 rounds a day through for several weeks.

    Then the bolt catch didn't work. No problem, shim shim, file down some things.... Ok, we're good.
    CO2 mags leaked. Dissassembled the mags, lubed o rings, reassembled.... Good.
    Noticed that the bolt has already wore enough so that it jams when travelling forward, staying half cocked. Filed it down... done.

    Every problem was fixed, but even after two weeks I can see this thing wearing down inside. I've tried some RA parts, with poor results, though I'm sure someone with more time could make it work. The problem is, I just want to shoot this thing. I like tinkering as much as the next guy, but this thing keeps having one more "little problem" that requires another order to Evive, a week of waiting, and hours of tinkering just to fail a couple of days later. I'm tired of the hassle, cutting my losses, and am investing in a gun that has better stock internals.

    "Hey Guys If Yall Are Thinking Of A Training Rifle That Works Like The Real One Get This !!!! Whatever Your Reason ... Get This Gun !!!!! +If You Guys Keep The Nozzle Assembly Lubed & The Other Key Parts Lubed You Can Expect It To Run For 4-5 Years Maybe More I Have Had Mine Since 2010 And Only Replace A Nozzle Assembly In 2012 Which Is Easy !!!!! Still Running Just Fine !!!!!

    "I'll have to give this one a 5 out of 5. Best gun I've ever owned and here's the little secret... I take care of it. As long as you properly lubricate the gun and clean it after EVERY game like you should for a real firearm, you wont run into many problems. You will however break nozzles after a while (easy fix). Since this was my first GBBR it's been trial and error with proper maintenence but I found the right balance of lubricant. Make sure you use silicone grease not oil (makes O rings seal better and wont wash out or dry up unlike oil). Also, make sure you clean out the old lubricant before adding more as overlubricating the gun is NEVER good. Upgrades are limitless with this kind of airsoft gun unlike some AEGs. Upgrades are also not hard to install, there's a huge amount of videos that you can find on youtube to help you out. Shoots a little hot for indoor so you might want to install an NPAS to get the FPS down. Get the RA Tech one as it's really easy to adjust. Installation is not hard to do but be prepared to fight the Bolt Carrier pin because it's stuck in there well (I had to use a hammer to get it out). Can't get enough of the instant trigger response that the GBB has and the flexibility of the gun. Upgrading this gun further than that is not actually necissary but fun to do, it preforms quite well stock. Really not enough I can say about this gun, love it. Just live by this, what you put into your gun is what you're going to get back out of it. Clean it and maintain it properly and it'll work like a dream. Also if something breaks on you which happens on all guns, there's a whole host of replacement parts available on evike for a steal.
