I plan on getting a new gun. I will then upgrade it into a DMR. I will be putting a 6.01 550mm tight bore, a magnum motor, and a new gearbox to handle a m150 spring. I will also be getting a avocado burst control mosfet to make it semi only.(most fields wont allow me to use auto with a m150 spring in the gun) Is it a good idea to do those upgrades on this gun. www.evike.com/product_info.php?cPath=21_44_214&products_id=28236Thanks for your help

That would be a decent base for a DMR. I would reccomend that you do some research into custom mods and tweaks that you need to do to have a reliable high fps gun. There are ways to drastically improve performance and reliability that just take work.
Some keywords : Aoe, sorbothane, bevel to pinion shimming, radius corners, and many others.
I would also recommend thatyou research more into your parts list. Just because they are pricey, doesn't mean they are good. For example, Systema parts are some or the worst and are also among the most expensive.
You could also just hire someone like myself who has experience and can make sure that it is done right.

About the only thing on that list that I would get would be the Avacado.
Barrel: Madbull v2 Black Python 509mm 6.03 diameter. 6.01 barrels are not good for accuracy generally. The looser the bore, the more accurate, and the tighter the bore, the more FPS. Alot of the people like myself who build guns tend to go for a 6.03 or a 6.05 for a good mix between accuracy and FPS.
Gearbox: The gearbox that you have listed is pretty bad. I have had personal experience with it, and the general consensus on the more advanced technical forums is that they are rubbish.
Instead I would go with a Lonex 8mm gearbox shell with a complete custom set of internals.
Motor: The Matrix motor is ok, but thats it. The best motor choices for this build, (both of which are more powerful than the Matrix), are the Lonex HT motor for ~$45, and the SHS HT for ~$30.
You can take a look at my thread in the gallery where I actually listed every part that I am using in my personal DMR at the moment. I can also sell you everything that you need for the DMR aside from the barrel and the MOSFET that you chose as well.
Are you going to be putting this together yourself, or will you need tech service?

I am going to do it myself, i know how to disassemble and reassemble the gun. Also i know how to do the wiring. I think you changed my mind about the barrel. But i am getting a 550 mm, then i will cover the rest up with a mock silencer, just so the range will be a little longer. I am not really pro at the gearbox stuff. Do you know any complete gearboxes? I want at least a gearbox that can handle a m140 spring, but i really want one that can handle a m150 spring. And lastly, can you send me a link to the SHS ht motor.

Well a lot more needs to be done to a gearbox to make sure that it can reliably handle the stress of an m150. There really arent any gearboxes out there that can just take it out of the box. The reason for the 509mm barrel is because much testing has been done and there are no increases in accuracy or range with any barrel over 455mm. It can actually diminish accuracy to go past that. shop.ehobbyasia.com/shs-ultra-high-torque-aeg-motor-long-type.html

The Lonex box is actually what I use in my DMR. If you go to my gallery thread, I have a list of what I installed in my rifle. There are a few little tidbits that I didnt have to buy so they arent listed.
I can also sell you this stuff from my supplier for cheaper than these other retailers.

It says in the gallery that you are using a m150 spring. Does the lonex motor pull it, or did you have to downgrade. If it does pull, will the gearbox shatter, or will it be fine with the right internals?

Yea the Lonex motor pulls it fine on stock ratio gears. That is the power of a neo magnet torque motor on a good LiPo.
The gearbox will hold up with the correct parts, as well as the custom mods and tweaks I mentioned earlier.

Just to state an "opinion": What is it that you want your DMR to do? Sniping or just long range shooting within the FPS range for rifles other than a sniper one?
