Thanks Colin, I've spoken to AK2M4 and a couple of xt springs are on the way. Hopefully this is all that is needed to rectify the power loss.

Hi all, Off the back of my Specna adventure I also decided to upgrade the Warthog 12". Replacing the standard 330mm 6.08mm barrel with a ZCI 340mm 6.02mm barrel. New ZCI rotary hop and Maple leaf maceron 60 and omega nub. Before I did the upgrade I played a site yesterday, the gun originally chronod at avg 321fps on .2 with hop set. On site it was about 297fps on .2. I've played a few days since it was chronod and the gun was new from shop when I got it. So it's not done much. Is it normal to drop that much after a few games, bedding in? Anyway, I got the same results when I got home and checked fps. So I upgraded the parts anyway, the fps increased marginaly, I'm guessing due to barrel, to around 306fps on average using .2. For reference I use .25 in game, which is giving an avg of 265fps now. Does anyone know what the factory spring is in this rifle? I was thinking of upgrading it to get a bit more out the gun.

Thanks for all the replies. I've learnt a lot, now to order a stronger spring and cylinder and have a play :)

I'm really not familiar with the gearboxes yet, are all cylinders the same size, just ported differenlty for different barrel lengths? Is that all i'd need to change to compensate for the smaller barrel?

What would you recommend to do to do it correctly, I don't want to destroy the gearbox. I have no idea on the internals of the gearbox, I found this on the internet about what's inside it: reinforced polymer piston. – aluminum, sealed nozzle – aluminum, double sealed cylinder head – aluminum, double sealed piston head with bearings – a spring guide with bearings – a set of steel gears – 8mm ball bearings I checked the slots on the original and new barrels, the slots matched great. Both barrels with the same bucking fit superb in the same hop unit.

Hop completely off on testing for both barrels.

Thanks guys, what spring would you recommend? Currently has M100. Glad I don't need to do something with the cylinder volume or gearing.

Hi All, I'm new to airsoft, but wanted to modify the SA-E11 becasue I didn't realise when I got it that the barrel was 300mm long and was full length inside the silencer. I wanted to replace the silencer with a shorter tracer unit. So to achive this, I took the silencer off and measured the barrel lenght that protrudes out the outer barrel, 93mm. I ordered a ZCI 6.02mm bore, 200mm long, stainless barrel. The original is 6.03mm bore. The rifle is fitted with a M100 spring. Getting around 320fps using .20 on standard barrel. After swapping the barrel over, i'm getting around 265fps. As this seemed quite steep of a drop I put the original barrel back and it's back to normal. Only the barrel was changed, bucking, nub and hop all same. Does anyone have any advise on getting the power back up? I'd like to keep the shorter barrel so I can use the tracer unit for CQB, but also as a backup for woodland play. Thank all.
