    http://www.airsoftworld.net/ They have a bunch of Modify parts.

    As in retailers? I don't think so, but AirsoftPro.cz should be willing to ship to you. It just takes patience, anyone can do it.

    Oh wow, somehow I didn't get notified when you posted your reply. Sorry about that! I just had another go at logging into the registry and it worked fine. I must have had caps lock on or something last time. Thanks for letting me know about the Kanzens. They were going to be the next bearings I tried. I can't remember anything specific about those Modify gears, but I know they're prone to failure. When it comes to gears, SHS are just as reliable as other gearsets bar Siegetek. So either buy SHS or Siegetek, because anything in between is uneconomical.

    Woops, somehow I missed your post. Sorry about that. I also totally forgot about my promise to measure pistons, so I'll get on with that shortly. Thanks for reminding me. Thanks for sharing your list, it's good to know of a few more parts which work. I'd be cautious of using those bushings though, because RiotSC only recommends Modify tempered stainless steel bushings, or ceramic bearings. The gear axles are so hard that they will wear down other bushings over time. Unfortunately I can confirm that neither of Modify's 8mm offerings are compatible with Siegetek gears in the Masada gearbox. My next try would be Kanzen ceramic bearings, but they are known to be fragile so I wouldn't run them hard, if they even fit. But let us know how the 5KU bearings look after a few thousand rounds.

    I'm sorry if you got that impression. All I've been trying to do is clarify what you've been telling us. We are all trying to get the best out of our Masadas, so we need accurate information. Aaaah ok. That's interesting, because my stock bushings worked fine with those gears. However, in the past I received a Siegetek bevel gear with an axle that was slightly too thick to fit into any bushing. Apparently there can be imperfections in the coating process. RiotSC is very good about replacing faulty gears though, so manufacturing defects aren't a concern. Other users have reported no problems with Siegetek gears and stock bushings, so yours might be another case of slight manufacturing imperfection from Ares, Siegetek or both. Sorry, it's been a while and I don't remember what problems you were experiencing. Are you saying you've had gearbox lockups with certain spring/piston combinations? Nobody has mentioned solid spring length, which is the only measurement you need to think about if you're concerned about spring length causing lockups. Extended spring length tells us little, because different springs are made with different wire thickness. You have to accurately measure the wire diameter, then multiply that by the number of coils to get the solid spring length. Then put your piston of choice into the gearbox along with the sector gear and spring guide. Move the piston to the release position, then measure the distance between the spring guide base and the front inside wall of the piston. There's plenty of room for the PDI and Guarder springs I've tried (PD1 120/130, Guarder 110-130), but of course I wasn't using the ridiculous weight that came with the stock piston. Why on earth would an airsoft tech try other bushings if the ones he's using seem too tight? Sarcasm over, RiotSC told me the only 8mm bushings you should use with his gears are Modify 8mm tempered stainless steel. His gears are so hard that over time they will wear down softer bushings, so I would regularly inspect the bushing holes to make sure you're not about to destroy something in there.

    I guess some people are just not technically minded and don't understand the need for clarity. When it comes to technical matters, I stand by my previous statement: Vague descriptions are useless. Describing technical details in vague terms, the way you continue to do, is a waste of everyone's time. Your guy is not unique in his pursuit of perfection. All good professional technicians focus in on the smallest details in order to make everything work as well as possible. This is exactly what we're trying to do right now with the Masada, and you claim to have some helpful information about it, but you are unable to communicate it properly. So now you're suggesting that the gears didn't actually need any modification at all, but your tech decided to sand them anyway?

    Ok, now I know you've completely failed to understand everything I've been trying to tell you: VAGUE DESCRIPTIONS ARE USELESS.

    Sounds like he's being intentionally vague. I hate it when professionals try to hide stuff from their clients. It happens all the time unfortunately... People try to make the job sound more complicated in order to justify a higher fee. I guess the 'gear modification' thing is BS. Besides "maybe just some work here and there with sandpaper" is about as useless as you can get.

    ASM is about sharing information accurately. Everything has to be scrutinised, it's nothing personal. If you try to present misleading or vague statements as facts, it will get noticed. For that reason, it contains a goldmine of useful information which you can read. Anyway, I'm looking forward to hearing about what your tech did to your gears!

    For people skimming or just recently picking up the thread, it's confusing. You have to be clear in your posts otherwise they can be misinterpreted! BTW you haven't replied to the thread on ASM.

    Me too I don't think spares are available, which is a shame because it's been out for a while now. Lol! So why did you include the piston in your parts list?
  12. Tacitus

    MagPul PTS MASADA ACR

    Thanks! Good to be able to add some more parts to the compatible list. I have a few questions: Did the piston go in at all? If so, specifically what modification was needed? If not, why is it on the list? Also, you mentioned over on ASM that the gears required modification. Can you specify what needed doing exactly?

    That would be wonderful! So where did 32 RPS at 410 FPS come from? Finally someone with some useful information! What else have you got running in your Masada? How's the performance?

    Yeah, it's *suitcase*. But I made my own which works nicely.

    I'm not heated up, I'm just keen to keep useless information out of this thread. There are many problems that are unique to this gun only, and we need to figure out with as much accuracy as possible how to get the most out of it.
