tgrillo Posted August 7, 2006 Report Share Posted August 7, 2006 Pretty much self explanitory, I want to install it into my V1 G&P M4. If I buy the systema one, I will buy an FF STRIKE Chamber for it, but how good is that supposed air seal and barrel lock feature on the Prometheus Unit? Also, if I just buy the prometheus, are the G&P hopup gears/springs good for the prometheus one? I'm thinking I'll just get the systema and an FF STRIKE chamber, but the air seal on the prometheus sounds interesting. Thanks Link to post Share on other sites
ronburgundy__ Posted August 7, 2006 Report Share Posted August 7, 2006 I would get the prometheus, mine should be coming tomorrow or wednesday, ill tell you how it is. Link to post Share on other sites
TriChrome Posted August 7, 2006 Report Share Posted August 7, 2006 The First Factory hop-up with the strike chamber costs something like $1 more than the strike chamber alone; so of course you should get the First Factory hop-up with strike chamber. Link to post Share on other sites
tgrillo Posted August 7, 2006 Author Report Share Posted August 7, 2006 But should I also pick up a Systema Unit so that I can steal the gears and springs off of it and put them on the prometheus, or are the stock G&P hopup parts good? Link to post Share on other sites
ronburgundy__ Posted August 7, 2006 Report Share Posted August 7, 2006 Well I think that the strike parts are teh only ones that really affect the accuracy, so it shouldnt matter i dont thnk Link to post Share on other sites

tgrillo Posted August 7, 2006 Author Report Share Posted August 7, 2006 No, what I mean, is what hopup unit are you using right now and what gun do you have? You are going to need to use the gears/springs from the hopup you have right now on the prometheus because it doesnt come with them. Link to post Share on other sites
ronburgundy__ Posted August 7, 2006 Report Share Posted August 7, 2006 I have a tm m4, it has a hurricane hopup right now. I know Im going to have to use the gears and stuff, but they shouldnt matter, because if they did they would be included, dont you think? Link to post Share on other sites
Node Posted August 7, 2006 Report Share Posted August 7, 2006 Just out of interest, does replacing the hop unit make that much of an impact on the accuracy? or is it more for when youve broken the one you have (some how). Link to post Share on other sites
ronburgundy__ Posted August 7, 2006 Report Share Posted August 7, 2006 It would depend on the hop unit you replace it with. Some have better airseals than others, most are better than stock ones which are usually lower quality. Say a stock TM M4 hopup is 2 peices, so it has a worse airseal that a onepeice.

Node Posted August 7, 2006 Report Share Posted August 7, 2006 How about the ICS M16 ones ? Link to post Share on other sites
ronburgundy__ Posted August 7, 2006 Report Share Posted August 7, 2006 Im not sure, but it cant hurt to try. hopup units are like 30$, just tack one on to an order you already plan to place. If your gun is shooting good now, dont replace it. If it isnt broken, why fix it? Link to post Share on other sites
fal Posted August 7, 2006 Report Share Posted August 7, 2006 FF hopup unit does not include all the gears. It only comes with strike gear set. This means you need any other M16/M4 hopup unit to get other gears from. Both Systema and Prometheus are good. But the question is how much difference. Prometheus hopup unit is too new. It just became available over a week ago. Thus naturaly, there aren't any thorough comparasion between the two, so you will just have to try it yourself. I would go with prometheus though, IF you have other gears. They supposedly prevent from rotation when its installed to hopup unit, and you get finer adjustment. And you can trust it will be on par with Systema quality, if not better. If you don't have any other M16 hopup units to get gears from, then start with systema. Set it up, test it, if you are happy with it, leave it untill you are ready for Prometheus one, if you want to. That way, you can actualy see the difference and let us know how it is like. Also another important thing, is nozzle. I heard very good feedback on KM TN metal nozzle. It is known to give 5~10FPS increasement just by replacing from Guarder nozzle to KM TN nozzle.(on Systema hopup unit.) I never heard anything about Prometheus nozzle. Though, like what Ron said, if your gun shoots fine, just leave it. Maybe just getting Big Out H-Hop nub would be the best thing you want to do. If it has problem, then you can start replacing cheaper parts such as nubs, then hopup rubber, then hopup unit and barrel and so on. Link to post Share on other sites
tiff_lee Posted August 7, 2006 Report Share Posted August 7, 2006 I have a G&P SPR/A which came with a metal hop as standard but the accuracy sucks no consistancy when shooting at all. Do you reckon it is the metal hop itself of just the rubber? Link to post Share on other sites
tgrillo Posted August 8, 2006 Author Report Share Posted August 8, 2006 Fal, what I'm asking is whether or not the G&P gears would affect accuracy if I put them in the Prometheus Unit. I am willing to buy the prometheus unit, but I'd rather not spend the $30 on the systema if I have to. If the G&P gears are fine and wont affect accuracy, then I'll just buy the prometheus and install my G&P gears into it. If I use the prometheus unit, should I get the systema, guarder, or prometheus air nozzle? Link to post Share on other sites
ronburgundy__ Posted August 8, 2006 Report Share Posted August 8, 2006 Your gears will be fine. Link to post Share on other sites
tgrillo Posted August 8, 2006 Author Report Share Posted August 8, 2006 Alright, when you install it tommorow make sure to test it out afterwards and post it here Make sure to leave some instructions or something on how to get the air seal parts to work.. Link to post Share on other sites
ronburgundy__ Posted August 8, 2006 Report Share Posted August 8, 2006 Well, I had to make 2 seperate orders to get everything i wanted, so i get the hopup and tightbore in one order, and the hop bucking in another, so a review might have to wait a few days. ill be sure to post though Link to post Share on other sites
trfo2o Posted August 8, 2006 Report Share Posted August 8, 2006 my first factory strike chamber got here to my house. I'll test it out in a few days with a guarder 1 piece metal hop up as well. Link to post Share on other sites
ronburgundy__ Posted August 8, 2006 Report Share Posted August 8, 2006 Mine came today too. But, I couldnt really use it. My current hopup didnt really work too good with it. To screw on the big gear, the screw was a different size. And I was missing some little clip things. I can tell you, if that barrel lock is a 'feature', it WORKS. I wanted to change back to my other barrel to see the difference, WOW. It look atleast 10 minutes to get it off. I have to screw around with it alittle bit more, I think I put something together wrong. Whats this airseal you talk about? I didnt do much research on what the strike kit does.

tgrillo Posted August 9, 2006 Author Report Share Posted August 9, 2006 Which unit should I get (for robbing parts such as spring/gears), guarder or systema? I took my G&P apart today and the spring on the back of the unit is missing (G&P doesnt put them on their guns), so I'm going to have to buy another hopup to take parts off. The question is which will fit Oh, by the way, the reason my G&P wasnt firing was because an inertia black bb jammed my prometheus barrel (I jinxed myself in a previous post last week), looks like I should stick with AE for now on. I have 10000 rounds of AE here now TRF20, the hopup bucking is horrible, it protrudes aboug 1-2mm into the barrel at max setting, and is extremely tempermental. STRIKE chamber here I come! By the way, did you get the STRIKE Chamber or did you get the full hopup unit with the STRIKE? If you got the whole unit, how did your Guarder parts do when you installed them on the prometheus? I am still wondering why G&P did not supply a hopup spring with the gun, this is worrying me, cause maybe the outbarrel/hopup will have fitment issues when I get the prometheus Link to post Share on other sites
trfo2o Posted August 9, 2006 Report Share Posted August 9, 2006 I got the strike hop up arm and dial set (not the full metal chamber). All I can say now is that prometheus soft buckings suck. Now for some reason I'm having terrible missfeeds and I also hear a weird grinding noise when I put it on full auto to get the bbs to feed. I put my guarder bucking back in and it works fine no weird noise and no missfeeds. I think the reason is because the prometheus bucking end (where the bb meets first before hitting the hop up "bump") is a little smaller in diameter and longer so it prevents the bb from getting shot out by the airnozzle. Or the end cups in a little too much making the diameter smaller for bbs to get through. I can't for the life of me get it to work. What's F'd up is it worked when it first came to my door and when I didn't have a strike chamber yet. but I only tested about 68 rounds worth so I dunno. I'm having AEX take a look and if they can't fix it, they are putting in a systema bucking or guarder %50 clear-if they get any in stock by the time they are done looking at my gun. Otherwise my guarder %70 black hard bucking is just a tad bit too hard and while it gives great range, the accuracy isn't as good as my older soft clear guarder bucking (which ripped when I tried taking it out for the KM) Anyway by thursday or friday I will update everyone with a completed accuracy test. I'll try and get pictures of the range and target, but it depends if my GF will let me borrow her camera. Link to post Share on other sites
ronburgundy__ Posted August 9, 2006 Report Share Posted August 9, 2006 I jammed my prometheus barrel with this stupid gay bb's. I thought it was the hopup unit and stuff, but it turned out to be the bb's. greeeaaaaaaaaat. If you are having misfeeds and stuff, take the hopup unit all apart, and just put it back together. Thats what i did, and its doing pretty good now. My prometheous soft bucking and KM RH65 have yet to come, and ive yet to do any good tests because i dont have alot of bb's Link to post Share on other sites
tgrillo Posted August 9, 2006 Author Report Share Posted August 9, 2006 I guess I'll just get the KM65, Guarder 50%, Prometheus (already have it), and Systema buckings. TRF, is it possible that your H Hop nub is causing the problem? This is really dissapointing because I wanted to use my prometheus bucking in conjunction with the prometheus hopup and barrel because they are all probably meant for each other. I'm getting a Guarder Hopup unit as well, so if the prometheus unit sucks I'll just put the strike chamber and guarder bucking in the guarder unit. How well does the guarder bucking and the prometheus tightbore mesh? I know you are supposed to match hopup parts by manufactorer, but maybe guarder works well with prometheus.
