Thinking of coming over to the GBB dark side

Postby Shiloh » Tue May 04, 2010 5:59 pm

First: Mods, If this needs to go in a different forum/locked because I'm an idiot/etc, feel free to do so.

I've been eying GBB rifles for a while, mostly the M4's. I've really been wanting a bit more realism in my game, and these rifles just seem to fit the bill really well.

Now I may be wrong on this one (probably am, this is just coming from a few articles I read), but aren't GBB rifles, in their entirety, simpler than an AEG? No gears, pistons, cylilders, shimming, etc, to worry about. Like I said, I may be wrong, but it's just a thought. And since I'm really not a technically inclined person, it seemed like a good solution to my constant gear/cylinder/hop-up problems I have in my AEG. Is this true? Or am I just being derpy derpy with this one?

However, I've been trying to weigh all the positives and negatives as objectively as possible, and this is what I've come up with.

PROS:
-Realism
-Relative reliabilty in performance, at least in warm weather
-Easier to repair/work on (once again, just my thought)
-Some parts are AEG compatable

CONS:
-Magazines are damn expensive, even the cheap ones
-Doesn't work during cold weather
-Repair parts may not be as easy to come by if needed
-Have to learn to play differently to accomodate for lower magazine capacity. (I'm not a spray-and-pray guy, but still. A 120 round midcap is a lot different than a 50 rounder)

My plan, if I do decide to get one of these guns, is to use my TSD shotgun during the fall and winter, or whenever the weather calls for it. I actually had to do this during Conflict Europe, since my AEG took a dump on me. And I learned that changing up play style with a spring weapon is actually...a lot of fun! Sure, I may not be getting those far shots, but it's a good challenge to try and sneak up on a guy close enough to tag him with a $60 springer. :lol:

The GBB I was looking at primarily was the AGM M4, due it's cost and, at least from what I had gathered, performance compared to a WA/G&P. Yes, it may not be AS good, but with some TLC and time, I'm sure it could be a skirmashable rifle.

I've heard the main problem with the AGM, however, is it's hop-up system and gas consumption. Could the last problem be due to the mag, or is it something internal?

I realize that changing to a GBB may not be as common or economical in the long run, but after shooting a few I was really hooked on the idea. My play may be affected, but maybe that's something worth dealing with.

What are your thoughts? Is there anything I should know about the AGM specifically?

Whew, long post. Anyway, thanks for reading and any constructive criticism is welcome!

While GBB rifles are 'simpler' than an AEG in terms of number of parts, they are much more finicky, and are hard to make as reliable as an AEG.

The AGM's gas use isn't due to the mag, but due to more friction and less precise mating between moving parts inside the gun.

With the AGM, to get it skirmishable, you're likely going to be buying a lot of WA compatible upgrade parts to get to to function reliably with decent performance. While a G&P WOC is more out of the gate, it will probably be better performance for less hassle for the same price in the end.

I would point you to the KJW, as I've heard good results with those without a super-high price.

Thanks for such quick replies, guys.

One thing I thought I'd mention is that this is probably going to be a spring/summer gun only, maybe 4-5 months out of the year. That's why I'm not too worried about getting EXTREME quality, but something I can gradually build off of and hopefully make a relatively formidable rifle.

The KJW sounds interesting. Do you happen to have a link to it? My browser is being finicky, so I'm having to use my iPod.

Well I'm trying to keep the initial cost under $200 if possible, and I'm sure I could go up to 250 if I could get a really good deal, but I'm pretty sure the KWA is going to haul in a pretty hefty price tag.

good luck getting a GBB rifle that's scrim ready for less than 250. you will need a NPAS system, new hopup, and other small parts

If you do get a GBBR get KJW mags they're plastic so they dont cool as much. I'm doing good. Your pistol got picked up today and is on its way to your post office

The AGM is ok, but what I've gathered from the MASSIVE thread about them on arnies, is the hop up sucks a chode, and the bolt head is gonna break since its a bad plastic. They also have issues with the bolt catch working right. Sometimes it works fine, sometimes it engages after every shot, sometimes it never works. To make the AGM workable, you'll need to mod the catch a bit, replace the hop up, and the BCG. Ebaybanned has replacement of all those parts and more, so it'll help keep the price down. Also keep in mind the mags are HEAVY, more heavy than a RS fully loaded AR mag, so having 5-7 of those banging around in a dump pouch is gonna be noisy and annoying.

If you really want to do it right, plan on spending more. The KJW is gonna be quite awesome out of the box, but the only mags for it are the ones they make which look like themamold mags (which if you like that look works great).

Theres also the VFC and KWA GBBRs coming out. I haven't heard much about the KWA, but RAtech did a quick overview of the VFC and it looks like it'll take all the same parts as the WA system, though the mags appear to be different (I could be wrong, but one thing going for them is they are 34 bucks a pop which is the normal going rate for just about any GBB pistol system). It comes with an improved bolt catch system and a roller hammer (the hammer has a bearing roller on it to help reduce friction with the BCG so it works better) and what appears to be a better designed hop up, at least compared to the G&P/WA and AGM GBBRs. If you do decide on the KWA, its probably going to be based on the WA system so hopefully part support isn't just limited to KWA, but we'll have to wait and see on that...


As for use in cold weather, I've heard of people using their upgraded AGMs in Sweden just fine, so you should be ok assuming you don't leave it in rock n roll mode all the time.

Cold weather usage usually requires an NPAS bolt, which are spendy. I've been looking at them for quite some time as well, and it seems like the customer satisfaction is highest with the G&P / Bomber, followed by WE, KJW, WA and AGM. The AGM as said previously simply requires work, but it's expensive work.

Lots of great info here, guys! Thanks!

I'm going to wait for some more details on the KWA, just to see what it's got to offer. I'll start saving now and working a bit more, and hopefully if it's under $350 I'll take a look at it. Knowing KWA, it'll probably be good. I saw airsoftology's review of it on youtube, and seems REALLY cool.

Guess I'll just keep looking. Still, if anyone's got any other good info, I'm all ears.
