    G&P GBB M4A1 family

    I just ran my GBB for an OP this past weekend. My old GHK mags are still going strong... well... maybe not strong but they're still working as they did when I got them. I have an EB mag (the ones that come with Viper guns) and it leaked out of the box. But it's a round seal design so I can fix it. I tested out 2 new prototype mags that were promising. Round seals, lightweight, but the feed was not perfect. I had to modify the feed lips a bit to allow feed, but by that time they were just a bit loose for reliable operation. Other than that they were perfect so I'd expect them to make it to production. I should note that I run semi-auto only and my gun is now more of a melting pot of parts than a G&P. Most notably, I'm running an RATech aluminum Bolt, Prime steel BC, RATech buffer spring, RATech inner barrel, RATech hopup rubber. There are 2 parts of failure on mags. 1. Static seals. These are the structural components of the mags. For WA mags, this would be the large rectangular o-ring that doesn't hold up to the pressure. 2. Dynamic seals. These are the o-rings on the moving part of the output valve. In my experience, excessive use of the gun leads to the output vale becoming sticky. This is due to dust and debris getting into the moving action of the valve due to the open design and also due to the poor qualities of silicone oil as the lubricant. This past weekend I tried out some MD Labs XF7 grease on those valves and had promising results. The thicker grease helped out with the seals and didn't leak out as much resulting in less debris getting into the valves. I did this on 1 GHK mag and that mag worked the best at the end of the day out of the 8 I ran with. Next I'm going to try out Dow 55 o-ring grease which is supposed to be o-ring wizardry. My goal is to be able to grease all my seals with a low friction, low adhesion lube and then run pure propane with no silicone since it seems that silicone is the item that causes my failures.

    To bring in a lot of WA user experience with RATech silicone O-rings here: Their fit starts out fine. As you use the gun more and more, the o-ring expands and gets tacky. Pretty soon, what was a good sealing low friction piston becomes sticky and sluggish. This can happen really, really fast, in as little as a magazine worth of firing. If you ever frequent the GGI forums, and you search for RA Tech or RATech o-ring you'll see that just about everyone who has bought an item with an RATech o-ring has had this problem. Some people believe the solution is to buy more of the $2 RATech o-rings. Others believe that using a material with chemical resistance is the answer. RATech knows about the problem with their material choice, they choose to ignore it. It's a shame because they constantly provide good concepts but fumble the execution. In this situation, there's no reason go with their product.

    Beware of RATech's silicone o-rings. They cause nothing but problems in the WA system because they are too soft and absorb too much oil. If you want to upgrade your KJW, stick with Cradle Airsoft's robust design.

    So your G&P mag works fine?

    No word, I'd expect to see them in the next 3 months.

    I have not heard of a confirmation if it has the G&P upgraded o-rings, In all likelihood it's a black version of the Bomber, which is a good mag. I was going to get one, but I'll wait for the CO2 mag.

    Mine came with metal filings inside the mag, inside the seal grooves. My release valve also would not seal. I eventually got it down to a slow leak, but it leaked more than my stock WA mags. I'm pretty sure I just got a bad one since it seems like few people had as many problems as I had out of the box, but it's also not like you can get any support from Pro-Win when their stuff goes wrong. Pro-Win using a free floating brass tube to secure the fill valve is just bad. I've been contemplating tapping the magazine body for a proper sized sleeve that could hold the fill valve. Their actual fill valve is the same as a GHK and many other Taiwanese gas magazines. I never had a problem using a speedloader to fill my Pro-Win mag, it somewhat confused me that some people couldn't do it.

    I heard good things about the G&P's from the few people that bought them. I had a terrible Pro-Win experience, I hope that it was just me getting an early model with poor QC but the fill valve is a quite terrible design by Pro-Win.

    The question is, who makes ARES's gearboxes? ARES themselves were a contractor for STAR, anyone that has had anything made in China knows that brands have contractors that have sub-contractors that have sub-contractors that have etc... From the secrecy of the development, it would make sense if they contracted plenty of different parts out to different companies. I have customers who do that.

    I believe it needs to have that range so the chamber can vent gas quickly. The WA system does that too and can lead to torn o-rings. I bevel and smooth out that point to prevent snagging.

    The extensions at least are on this very page.

    He bought it new in the U.S. No luck with contacting other retailers or the manufacturer, or distributors.

    My buddy got one of these but he didn't get a metal flashhider with it. Does anyone know where/if I can get a Type 97 style metal flashhider? Or maybe someone would be willing to part with theirs? Thanks

    Or you could sell it to me for cheap

    With as many parts as I have changed on my WOC, one part that I have never wanted to change has been the hopup system. I have changed the rubber to the RATech red hop bucking, but the actual hopup system gives me greater range and accuracy than my Pro-Win mechbox'd M4 and on par or a little better than my teammates' best AEG's. It was truly surprising and I'm sure the .30g BB's had a lot to do with it.
