I've had my LVOA for about 4 weeks now, and each time I've had the gun chrono'd at our field the fps has steadily been decreasing. My first time playing with it, it was consistently shooting about 397. The next week, it was down to 380, then the low 370's the week after that, and 360 the last time I brought it out. Any advice on what the problem could be and how to fix this would be much appreciated.

The spring is going to settle, but I'm also going to need more information to see if we can figure this out.  
  • Which brand and weight BBs are you using?
  • Are you consistently using the same BBs for each chrono?
  • Is the same chrono being used each time?
  • Has the hop been changed each time you chronoed the gun?
  • Approximately how many rounds have you fired before each chrono? Total?
  • Have you tried cleaning the inner barrel?
  • Apart from seeing the chrono tell you it's shooting at a lower velocity, have you noticed a decrease in performance while actually playing?

At our field, the guns' fps get measured with the same chrono every weekend before playing. They have their own magazines filled with .2's that they use for measurement (I'm assuming either elite force or valken bb's as that is what they sell there). I personally use elite force .25's when actually playing. I'm honestly not sure about where the hop up has been before each measurement. I have had to adjust it a lot, because for some reason when I use my mid caps, I have to turn the hop up a lot in order to get any range. With my high caps, I have to turn it back down. Before the very first chrono, I hadn't gone through many rounds at all, maybe 3-400, and hardly adjusted the hop up. After that, I've probably gone through over 2000 bb's each weekend. I have not cleaned the inner barrel yet, but am planning on doing that sometime this week. During games, the gun even at it's its lowest fps measurement still seems to have good range and accuracy, and has not been less effective. I'm just worried that the drop in fps seems pretty steep and has happened steadily and I want to make sure it's not indicative of a potentially big issue.

That's interesting. 360-370 FPS is correct for an LVOA-C with .25g BBs. It's possible they may have mixed BBs and tested with .25g instead of .20g BBs. Or, if they're using a chrono that you shoot through rather than over, it's possible they're striking the inside of the chrono which would affect the reading.  

You could always take advantage of our warranty if you want complete peace of mind.

Hello,
I would like to add to this forum with some concerns of my own. I took my one week old brand new LVOA-C to one of the few fields in my area today, it got chrono'd with a .28 elite force and was shooting at 303 pretty consecutively. Is this a normal(huge jump) for chrono'd .28g BB, compared to the .20g? Im planning on going to another field next weekend for another game/chrono. This field has a pretty awesome chrono set up, and forces .25g bbs(elite force to my knowledge) via their own mags for chrono. If its shooting lower than the 360-370 range, i may definitely be following up with my warranty, and may require the link. Please advise ! Thank!

Okay.... i must have gotten the worse M120(360-450 as Advertised) spring in the box, when you guys put my brand new gun together. When i chronoed the gun today at "Cartcon1" (field mentioned above)- i was hitting 300-310 with .25g BBs(elite force) w/9.6/1600nihm battery .. This is definitely NOT why i paid so much money to get this gun and have to change out the dang spring after no more than 5-10 hours playtime and the first two games i played. please let me know how to put in a formal complaint and follow up with warranty requests.

I have to say krytac - as a first time customer of your $400+ gun thru evike.com - im not very impressed.

Please follow up immediately.

Dr. Kaleidoscope,

Sorry to hear you're having a bad time with the product. Please proceed to https://www.krytac.com/warranty for details on warranty service.


If you'd like to troubleshoot your product, I do have a list of things to go through.

I notice you're using 0.28g bbs for chronograph. BB weights will affect velocity. Your gun hasn't changed output, but the projectile weight has gotten heavier. This will result in a FPS drop. Following the specification outlined on the product page you'll see a broad output marked for your specific model. The specification of a spring alone does not account for the configuration of hte gun. Which will affect the velocity.

Next, you'll typically see that velocity is typically calibrated per weight. Our calibration is done with 0.20g bbs. So note that using .28g bbs is not calibration standard, and will result in slower velocity.  Due to the nature of springs, it's normal for the gun to wear in and drop 10-15FPS within 2000 rounds. This is why initial chronograph velocity is much higher than a seasoned gun.
 
What type of chronograph is the field using, and did you turn your hopup off or at minimum, #3 setting?

Chronographs are not all equal in airsoft. Some fields will use firearm chronographs which are not calibrated for low velocity. Some will use paintball chronographs which are not set up to read a small projectile. So please confirm the type of chronograph.

The hopup setting affects your velocity as well, as the amount of friction from hopup will adjust the "hang time" before the bb ejects from the chamber. Typically, higher the setting, lower the velocity. #3 is the minimal setting for level hopup engagement and is the calibration setting we follow.

How many rounds have you shot through the gun?

Barrel fouling is typical of lower quality ammunition and residues will depreciate your velocity.

Have you conducted any maintenance in the timeframe of ownership?

Some users ritually spray down their gun with aerosol lubricants. This will depreciate your velocity. The manual actually does not even instruct using lubrication on the gun.

Likewise, are you using any aftermarket barrels or barrel attachments such as aftermarket flash hiders or mock supressors?

Improper barrels or aftermarket attachments can be obstructive, impede bb travel, and otherwise cause a loss of FPS.

Kraken,
I appreciate your response. I understand that you guys are using .20 BB's. Thru other replies for admins on this topic and my own comments I've stated that ive used both .28 (which actually comes recommended on the guns magazine, I'm sure your aware) AND .25 gram BB's. I purchase only competition/professional grade BBs for all my guns (primarly laser dot or elite force).

As another admin stated above this gun/spring is expected to shoot 360-370 with .25g, and im shooting 300-310. I am aware springs "set-in", but this is a HUGE drop in FPS for what is considered a higher quality gun out of the box. I would say ive probably shot anywhere from 2000-4000 rounds thru the gun since i purchased it on march 28th, 2017.

Here is the chronograph my local field uses..
http://www.evike.com/products/60352/

I have cleaned the barrel out, as the manual described with none lubed, and non-residual rag...
Outside of having my hop turned up to 8, i dont really think anything else would be "wrong" to causd such a major drop in fps. Honestly, i looked thru the warranty information, the processes in place for your warranty, and i may just end up returning the gun due to poor performance to evike.com. Id rather not go an extended duration without this gun to play with, after i have spent a good deal of money on it....just to send it off and you guys tell me this is actually expected performance. There was another gun i was considering against this one, that may have been the cheaper, better purchase after all.

you mightve just gotten a lemon. Krytac has some the best performing guns out of the box and im sure if you trade your model with another krytac from evike you will have a great experience

Yes, i agree. I definitely think something is not right here. Best part is it happened over a weekend, so ive been stuck waiting until monday to get any type of resolution from Evike or Krytac!

In short, i do not really recommend either at this point! Go local, if possible, and the shops atleast test the guns infront of you before you buy them!

I use the g&g .28 that come in the 5600 blue label bottle. Mine chronos at a 301fps but its a paintball field that let's us play there so they can make more money. So there is a big difference in .20-.28

Yes, the more people i talk too, the more im finding out the LVOA shoots "soft" out of the box. Im waiting to take it to the field this weekend to get it chronod to krytac specs. At that point, i will let everyone know what happens next.

Ultimately the accuracy and R.P.S. are great. I am losing some distance thanks to this "soft" shooting gun. Depending what the gun tech recommends, i may just change the spring out(it would be cheaper then sending the gun back for repair/replacement)... In short, i need to be right at field limits to hang with the HPA kids. Dont be fooled by the advertisement, this gun will not come right at those limits. You woll have to upgrade it.

Pretty lame for a $400+ gun.

OK so u want to compete with hpa players right? Good luck. The reason hpa is used is the on the fly adjustability. If they were to play straight up gun vs gun you would be on par vs them. Krytac lvoa straight out of the box will beat any other box gun, this dosnt count on custom builds like umbrella armory. I'm happy with what I get with mine and look forward to modding it for the better. I'm adding a 416mm Prometheus barrel and flat hop will update u on my gains.

Okay, i both agree and disagree with some points your making here. Yes, HPA's are highly adjustable. HOWEVER, 98.9% of playing fields have FPS, and ROF regulations. Its been my observation, all of the fields in my area have a max FPS of 375 w/.25 or 400 w/.20. So MY objective in buying my KRYTAC LVOA-C was to get right at those limits, so i could go toe to toe with an HPA player. In all instances of going toe to toe, it would be "straight gun VS. gun", and which point it would be up to the skill of the operator(s). One thing i completely disagree with is that krytac "makes the best out of the box guns". Let me show you why from my research, observations, and experience.

In short, i almost returned my KRYTAC LVOA... I got the FPS tested per krytac specs (hop setting @ 3 using .20g bbs) and it was shooting 350-360... needless to say i was very frustrated. When i called krytac, they had just given all of there distribution rights to Evike.com (HORRIBLE DECISION BTW KRISS/KRYTAC). When they found out i bought it from evike.com, they only suggested i call them about my issues... aka NO BIG HELP FROM KYTAC CUSTOMER SERVICE. SO, i call evike-- they tell me i would have to pay to ship it back ($30-40), and theyll repair or replace it.....completely ridiculous for a company that boasts MILLIONS of transactions, such great customer service, and i had a faulty product!

I contacted my home field back (Cartcon1), and they mentioned having 2-4 LVOA's prior to mine that they were told that came thru evike, that had the same issues as mine -LOW FPS RIGHT OUT OF THE BOX...mostly due to a BAD BUCKING & WEAK SPRING..that they had specifically made repairs/upgrades too. Luckily, my home field knows me well, and really try to look after the players/airsofters in general. They stated they would get it to field limits for just the cost of the parts(thank God for them!).

So they fixed it today and it was shooting between 370-380 w/.25g (OUCH!). Im expecting it to settle in right between the 360-375 range, which is perfect for all the fields in my area. IN short, i will not recommend KRYTAC or their licenced LVOA to anyone moving forward. Nor will i be purchasing anymore Krytacs for myself, family, or friends. With the falling quality in there products, complete lack of customer support, and horrible decisions in distribution - we could all start seeing krytac coming off the most recommended list across the industry....and passed up by there competition offering better products with longer warranties.... just remember you read it here first.

Just stepping in and saying there is an opposite to this. After 4 weekends. 6000 bb`s and a barrel cleaning after every second weekend im still cronoing what i did out of the box.. pretty consistent aswell. Between 393 to 397 fps with Valken .25 and hopup set to 3. Using PTS new midcaps.
This is not an issue for me, but shows the inconsistency of the LVOA-C.... and in sweden they cost 570 usd....
