I just realized that my gun is shooting 422 FPS with .2's. Note that the recording was from ASGI right before they shipped it, but it's still over the limit I think, for a full auto gun. Do I have to get a new gun, or can I just use semi automatic with really heavy BB's? (By the way, It's a Dboys MK17. If it turns out I have to get a new gun, expect to see one for sale soon)

All FPS readings for games in Michigan are measured with .20 gram BB's so your correct in saying your gun shoots too hot for a full-auto capable gun.
You can either drop in a weaker spring giving you a FPS reading that isn't on the edge like that, or you can get a new gun if you don't want to deal with the spring issue. It's up to you.
If the latter, PM me. I may be interested.

Here's the FPS limits from our event rules thread: OUTDOOR/OPEN FIELD ENGAGEMENT LIMITS • 1.0 - 340.9 fps - Arms length engagement limit • 341.0 - 400.9 fps - 20 foot engagement limit • 401.0 - 540.9 fps – 50 foot engagement limit, bolt action or permanent* semi-auto replicas only • 541.0+ fps - Prohibited or allowed with permission of event organizer only *Permanent semi-auto refers to replicas that do not have full-auto fire capability, no matter how the selector switch or other user input device is manipulated.
Your other option would be to make your gun fire semi-auto only, but that might be more difficult than changing out the spring.

Just a heads up, I also own a DBOYs SCAR that was shooting fairly hot (about 400-415 FPS) when I first acquired the gun, but after a couple of thousand rounds, your FPS should "settle" in to about 340-350 FPS with the stock spring. Mine chronos in at 344-348 FPS consistently after I wore the spring in a little bit.

Jeez, that's a lot of settling Myers. They must use pretty crappy springs in those Dboys for them to start that high and then lose over 50fps.

Yours might also have developed a small air leak somewhere. Not that settling 60 FPS is impossible, but it is extreme. With DBoys's known quality control issues, air loss seems like just as likely a candidate.

First of all, I'm definitely looking to get a new gun for two reasons. 1. This SCAR has too high FPS 2. There are NO economical magazines or upgrades for it! Anywhere!!! 3. I don't trust myself to take apart a gun to put in a new spring.
I might buy something from the commerce section, but most likely I'll just sell this gun, and with that $$$ I'd get something like a cheap ($125) JG MK36 and eventually upgrade it. I also seriously would need mid cap magazines for it. If anyone has other suggestions, that would be great. Here's what I'm looking for: 1. Cheap <$160 2. Highly upgradeable, magazines readily available. 3. reliable 4. This isn't important, but I don't really want an M4 or AK variant, they're too generic.
Thanks!
Edit: I have already put over 1000 rounds through it, and it doesn't seem much different.

Skip the JGs. They also shoot well over 400 FPS, and they're project guns. You've got to put a lot of work into them to make the reliable, which, if you know your war around a gearbox, isn't the worst thing in the world. If you don't want to put a new spring in your MK17, then you don't want to put the necessary work to get a JG in decent shape.
In your price range, the only really good gun is the G&G affordable series. Mostly they only make AR and AK variants, but I believe they have an mp5 as well, if that will suit your needs. They're reliable and good shooters. They come out of the box at about 360 FPS, and usually settle into the 340 FPS range, which is perfect because you can use it in CQB, and it can hold its own on the field. They're really quality guns all around.

Thanks! I think I'll go with the Combat Machine M4 Raider. The FPS (330) sounds kind of low, but that line of thinking got me into this problem in the first place. I'm going to buy a few midcap P-mags (they're compatible, right?) and call it good. One last thing: what weight BB's?

Can't go wrong with a G&G. Use .25s.

I really do think it is just the spring. My buddy has a DBOYS scar that has wayyyyy more rounds than mine and the spring is so decompressed that it chronos in about 190... And regardless if it's the spring or an air leak, I'm glad it happened because it's now shooting exactly where I want it.

No spring will drop all the way to 190. You guys have compression problems.

After doing a little bit a research, the majority of the DBOYS SCAR owners have seen the stock spring settle at around 350-360 FPS, so I'm not really believing my SCAR is having compression problems. As for my friends, I personally believe that he left the spring compressed and it just wore it out. According to the previous owner of his SCAR, he had left it unused for about a year. I think that definitely would justify the massive FPS decrease.
Shocking thing is, even with the incredibly low FPS, his SCAR was still easily getting the same range/accuracy as mine. Although it took about 3 more seconds for the BB to reach the target.

But the other problem with the SCAR is that there aren't any reasonable priced mags for it. I mean, $90 for 3?!? Come on! The price is rediculous. I might keep it a little longer if the FPS drops and mags become available. I'll give Dboys 6 more months to come out with cheaper mags...then bring on the G&G's!

I don't trust myself to take apart a gun to put in a new spring. Woah, woah... You're kind of making a mountain out of a mole hill here, aren't you? 1) The high FPS can be corrected by swapping the spring, which will cost you around $40 if you take it to a local shop or find someone in your area on MiA who would be willing to do it. 2) SCAR-H (Mk17) magazines are available. Sure, they aren't cheap or as readily available as M4 magazines, but you bought the SCAR-H for a reason, right? If you want to own a unique gun you have got to expect that there will be extra expenses to get it running. Remember, all you need to play is the included high-capacity magazine. Extra magazines are a bonus, not a necessity. 2b) No upgrades available? Isn't the SCAR-H basically just a slightly modified M4? V2 gearbox components should work for almost everything you need. 3) See 1. If you don't trust yourself, have someone else do it for you. It seems a little nuts that you bought the gun and now don't want to put the money into it to make it skirmishable, but you're willing to see it to finance a new gun and take a loss on your purchase. Why not just spend the bit extra to downgrade the spring and keep the gun? I'll give Dboys 6 more months to come out with cheaper mags...then bring on the G&G's! Good choice.
