To a degree this is correct, we did a stack of side by side tests amongst a bunch of us on a UK site about 10 or 12 years ago, and found that a 430mm barrel was more accurate than a 509mm or 550mm, and this was when volume optimising was in its infancy, when most, if anybody except us serious modifying freaks where doing it, or even heard of it :shrug:I thought barrel length of 430mm is the best for vsr cylinder (matched,better accuracy)
There are other benefits to volume balancing to a 430mm barrel, and not just that you can keep your gun a respectable and managable length....
There is the benifit that in a balanced cylinder the piston has time to build up kinetic energy before its being asked to compress any air, as opposed to the barrel/volume described above, which is asking the piston to compress the air right from trigger release.
The Oring in a balanced cylinder also has time to seat properly before having to perform any compression, so its being more effective when its asked to perform the compression, as opposed to the 5 to 10mm of compression stroke you lose while the O ring seats properly in a full compression style cylinder.
Some good info here though for the FNGs out there,....... sadly some of us are alot longer in the tooth, and have been doing all these mods in 1 form or another, for the better part of a decade and a half..... :yup: ...... God I feel old :ashamed:
As an aside..... RE the DE M50..... I bought 1 of these for my son last year, it now has a 90 degree trigger & piston, VSR guide and spring, TDC, LRB, exstended nub, 500mm AEG barrel, & is capable of in excess of 500fps with a .2.... Total cost was £50 outlay for the gun, all other bits were floating about in my parts bin >..... Any thing is possible if you have the where-with-all :tup:
