I am not from Canada and don`t know which regions speak french, but here is the link:

This is a guide, but not absolute 100% since those guys tune their guns to 300fps
My fps rates will be like M110 is 360-370 (.20 of course) fps with Xcortech (and Xcortech reads 10% more than regular fps). Adjust to that since there are people which can get 450 with M110 (major
)
Barrel length is as it says in link, but I wouldn`t concentrate "DMR build" on that. DMR is consistency (+/- 3-5fps, not power itself). Here is a wery good guide
http://airsoftsniper.proboards.com/i...ad=1291&page=1 Disregard all BS Famas talk since most of the forums know only TM Famas which is by today standards complete crap (at least). Jin Peng is somewhat better, but also crap, but Cybergun, which is at stock still child AEG can be modded to playable AEG or even DMR. TM can be top shit, but not with FAMAS, here is exactly opposite.
Parts as I personally tried an guarantee to fit: (Cybergun only, not TM, not JP)
-Clinder a bit longer, NOT stock V2/V3
-Cylinder head V7
-Piston regular V2/V3
-Piston head also anything that fits V2/V3
-Spring guide V3
-Motor V3, but with a few mm shorter axis, if DIY shortening find motor with D shaped gear
-AR latch stock V2/V3
-Normal springs, but expect a bit lower fps with higher rate springs due to longer cylinder space
By my experience most problems with stock gun is with airseal. If you have 350+fps with stock gun it is probably OK. If not most problems can be solved with filing tappet plate to seat closer to GB wall, and with that of course closer with hop-up unit. Next problem is cast 6mm bushing holes. If going nuts get them CNC-ed to 7mm, if not superglue metal new 6mm metal ones in too loose cast holes. That is the next problem. Stock XYZ (or something) gears will bind with closer tolerance, at least I had problems with 2 GB`s, so get yourself good V7 gear set. Up to M120 only bushing and shim job is enough. Anything other.....go nuts. Shell will hold anything, but don`t expect stock motor to run M140 long or stock cylinder head to seal perfectly.....etc..etc...
Again, DMR is in consistency and with that accuracy and that can be achieved on CG FAMAS with basic AEG knowledge. TB barrels are mostly BS, and if you don`t have knowledge to tweak existing platform to be better, than it is better to leave it to expert than buy TB barrel or any other "performace" part.
Hop-up unit is FAMAS specific but good enough. Add something in bucking since stock (with hole) is too soft. Cheapest rail is TM, anything else is DIY.
If you will go into details I can help. This post is already too long
