Guest PT247 Posted March 29, 2017 Share Posted March 29, 2017 I wouldn't use them if I didn't think they were worth the gain. So, do what you want as most folk will not buy a PDI and a ZCI and do this testing for you. Something I did do though was try various barrels on one of my Krytac builds. I tried an Orga 6.23mm WBB, a PDI 6.05mm and a Prommy 6.03mm barrel and matched the fps by changing the spring.... the Orga cost £90, the PDI £70 and the Prommy £50 (ish)..... They all performed on par with the OE Krytac barrel so I left the Krytac standard and sold on or used in other guns the "upgrade" barrels. So that is as close to a scientific experiment I can do with airsoft, results are in.... stick with your OE barrel.... or don't coz it is an ICS and not a Krytac.

Please don't get me wrong, i'm not questioning people's opinions, so if i upset anyone i apologize that's not my intention. It's just something i've been curious about whenever i hear about a specific brand. I may just have to do something similar, if like everyone says barrel length makes no difference as long as you are running the right cylinder and parts. I may just have to put the prommy in one, pdi in another and zci in another and see what the results are. Of course that's about as close as you will get as airsoft has so many varying issues with range and trajectory, like you stated above with your krytac.

Guest PT247 Posted March 29, 2017 Share Posted March 29, 2017 you haven't upset me, or anyone else mate, is a discussion, and opinions will always differ! :-) Like I say though, I doubt anyone has tried both a PDI and a ZCI in the same gun on the same set up so no one can give you a definitive answer. :-) Link to comment Share on other sites More sharing options...

Now i know to be truly effective i suppose i would have to buy 3 versions of each brand all matching the same 3 sizes, yeh that's not gonna happen lol. But considering i am making 3 upper receivers it's something to test. Link to comment Share on other sites More sharing options...

Site rules, 450fps dmr , 350fps full auto, 328fps my local indoor cqb r yes i'm aware that i could use the carbine version for cqb and change spring, it's just a project i've wanted to do. Take advantage of the split gearbox because if i don't it will sit there gathering dust and i hate not using it as i'm a big fan of ICS. I always try and make a loadout for each gun i have. edit - and i wanted to give them very distinct external looks. I know i could just use a carbine version for everything, the problem is i probably wouldn't, it's just me i always like choice. trying to decide which gun and loadout I take to a skirmish is worse than a woman buying shoes lol, i could spend a whole day trying to decide from military ones to my p90 stargate loadout for example. Plus airsoft is also the cool factor which does change your opinion on things. Link to comment Share on other sites More sharing options...
Guest PT247 Posted March 29, 2017 Share Posted March 29, 2017 there is something to be said for switching uppers and have the sights and accessories all set up with just a swap over. Far easier to buy 2 or 3 different guns though if the fps change is needed (although that would cost a wedge) Link to comment Share on other sites More sharing options...

If i hadn't have had the ICS i would probably not even thought of it. It is literally just the reason of opening a case and having everything ready at an instant swap, that is my entire argument for doing it, simple as that. And when i'm complete i'll buy something else and start a new project, i would like one of the krytac's, maybe the LVOA model or the new vector when it's released.

Tested them all indoors locked in a vice. Also tested bore diameters and straightness. Best average barrel I found was the pdi 6.08 but the 6.05 is better if you lap it. One thing I will say though regarding price is unless you have a really crap oem barrel its the least return for your cash so zero £s verus up to £70 is it worth it? Not really no.

Guest PT247 Posted March 29, 2017 Share Posted March 29, 2017 am tempted to buy another Evo3 and carry a couple of springs for various site limits, but my PDW shoots good enough for AEG games and generally use my VSR outdoors. Link to comment Share on other sites More sharing options...

Tested at 30 to 50 meters in 5 meter increments. Best flat out range was prommy 6.03 but groupings wasnt great. Best mid range groupings were orga 6.23 but a few too many flyers. Best groupings and consistency on average to long range was the Pdi 6.08 until I lapped the 6.05. Straightest and most even bore diameter was the PDI barrels both were way better than anything else. Keep meaning to redo it all in one day and film but either don't get chance or just cant be arsed. Link to comment Share on other sites More sharing options...

Guest PT247 Posted March 30, 2017 Share Posted March 30, 2017 doing it on an indoor range at 30-50m would be ace if possible as that helps remove the changing weather as it takes time to set each barrel up and outdoors conditions can change massively over the space of hours and more so days. :-) Link to comment Share on other sites More sharing options...
Hangtight Posted March 30, 2017 Share Posted March 30, 2017 It would be interesting to quantify the differences between barrels. I think it's one of the most 'over sold' upgrades and is probably one of the last things you should do when chasing performance rather than one of the first. ITH , would you mind describing your lapping procedure and materials? Link to comment Share on other sites More sharing options...

ITH , would you mind describing your lapping procedure and materials? I wouldn't day oversold but it is the last part you should buy. Hsa sell manufacture various manual lapping kits but I mainly get them machine lapped as its quicker and lapping by hand is tedious. Think airlab might sell kits as well.

Hangtight Posted March 30, 2017 Share Posted March 30, 2017 I have enough tedium in my life...I'll see if I can find a local machine shop that can do the work. Probably no more expensive then buying the HSA kit. Link to comment Share on other sites More sharing options...
