Or... just wing it 😉Potential range is a mathematical function of BB weight and muzzle velocity. There are almost no caveats to this, and none that are significant (aside from the obvious over-hop and holdover).
As for accuracy, most seem to agree that bore quality is the primary influence (in which case you'd pick EdGI- expensive and high quality finish), however some argue steel is a superior material to brass (EdGI is only brass), and many people claim modest-priced options like brass Maple Leaf Crazy Jets are as good as the best anyway. Then to decide on barrel length you need to know your cylinder volume and what BB weight you'll want to employ, which requires first picking a BB speed you're happy with, and THAT requires you know what muzzle energy you'll employ (which technically changes based on BB weight!), however you'll want to weigh this preemptive BB weight decision against available BBs' quality because not all ammunition performs equally (and if you think you want to run .43g but the performance of all .43g BBs is lacking, you might go with .45g instead- as example). Then once you have the easy part done, you can decide on inner barrel diameter- oh but if you pick wide enough, it changes the entire equation you used to pick barrel length. Good luck
Regarding bore quality, what about the all the hard grouping evidence of edgi and pdi vs. other barrels. Also, hs5 did a pretty cool video where he compared an r-hopped, non-lapped barrel to a barrel that had a stupid absurd amount of lapping pass throughs:I disagree with the bore quality stuff. It's about as much of an influence as the crazy people that sort and wash their bbs. Which is to say none. If it's somewhat shiny, it will work.
Barrel window and bore size. Tighter the better, and make sure the bucking you're going to use works with the window well or be willing to modify it.
Stock SSG's use a shitty aluminum barrel and still manage 80-90m shots. Its not because they polish the aluminum, it's because the hop up and barrel combo work well together.
430mm with .43g will work well for you, but if you decide to weight the piston you may choose a heavier weight for more energy.
Yeah that's total nonsense. Both my EdGI barrels are still mirror finish- one of which is plenty of years old. Sounds like this person maybe just looked into the window and saw BB gunk- because yes from my experience most plastic BBs quickly mark their presence opposite the window cut / hop up pressure (and you can also usually see streak marks at the muzzle).How good does the Edgi finish holds though? Because I have first hand witness saying the finish is indeed better than a mirror but after a game it looks just like a stock brass barrel. The claim is a few years ago though.
Right-click and inspect the page, you can find the YouTube key, copy that, paste it in Google and YouTube will come up. In this case it's rzhYR6s2kJEyour link didn't embed properly on the forum (they never do for some reason).
The steel seems to not gunk up as fast for one reason or another
