The 'overalls' appear to be Arcteryx Leaf if I'm not mistaken. I hope you've got deep pockets?

How was Tech Brigade? I've been meaning to get down there for a year or so but buying houses, marriage, surgery, babies and having to get a stupid job have got in the way so far. Is it the land of milk and honey? I'm near Ampthill btw.

I dont know of any decent bushing/baring manufacturers still trading but the above will get you started, the rest of the bits can be transfered from whatever stock M4 you buy xx

Crye JPC in RG(plates not included) Bought my own one for civilian contractor training when I worked for MoD. Lightweight and comfortable compared to the bulky issue kit they tried to fob us off with. G3 combat 'pants' are well worth the money too.

Sounds ideal, where are you thinking of playing? Ive still not got to a game yet, I have had some technical issues with my rifle not compressing correctly so I am rebuilding again this weekend. I'm happy to lift share but at 17mpg my car is extremely comfortable but a bit thirsty for fuel! Next weekend would be ideal for me, what's happening at the pit? Urban Assualt? Etc?

So I'm ready to go airsofting! My rifle is finished, my kit is good to go but I no longer have anyone to go with as my brother is moving to Denmark! Is there anyone reasonably local who would be interested in holding my hand and showing me the ropes? I have transport, I'm happy to travel and offer lifts. Does anyone play at TechBrigade or Urban Assault? Both seem interesting. Also, any techy/tweakers locally who might like to swap parts/ideas most welcome. I look forward to your insights

Light silicone oil of course. I had noticed that the Dytac midcaps can hold 150 BBs but they are sold as 120's and yes I stripped and oiled them when I got them.

"My milkshake brings all the boys to yard!!!" Cleaning rod, alcohol wipes and silicone spray in the loadout? What about sandwiches? I was considering making a gillie hood to stuff in pocket for woodland games?

Dude I'm blushing!

Yes, sorry #Airsoftwarrior147 rear pouches are just attached to my 2" rigid belt, I've just hooked the MOLLE straps round and back under the loops on the back of each pouch. Hopefully they won't get in the way, as they're at the back.

Yes its a JPC, still waiting for the G3 combats to arrive from 'Merica, but I only ordered them in February so I should really learn to be patient!! I'll probly wear my Lowa German military mountain boots. Just ordered a Turnigy and 2 Gens Ace 1300mAh 7.4 lipos, got charger. Cleaning rod!!! Cigarette filters aren't ideal I spose. Got some squirty squirty too, from Maplin. Thanks chaps, very informative.

Always come prepared!!! I had always assumed that these items were essentials, perhaps not the iPhone but I can imagine humming 'Ride of the Valkyries' and having to concentrate on fighting a battle at the same time could get exhausting!!!

Here I am at last, nearly ready for my first game. What am I missing? Apart from a pistol? I've got ammo, rifle, eye protection, hydration, med kit, iPhone playing 'Ride of the Valkyries' on repeat through low-profile ear peice, monocular, spare gloves and shemagh.

Well I'm going to reserve judgement until I've tried the Prometheus barrel with the right rubber and nub. This is my first build so its a learning curve. I don't know what results to expect, I don't even know what range an aeg should be effective to. I haven't even started experimenting with ammo yet either, it's all so exciting! So where does PDI come on the quality curve? I've ordered a 6.05 barrel, looks pretty standard, no fancy hop chamber, just machined from one peice. The problem I've got now is she won't fire full auto! Just stopped halfway through a mag.

Not exactly the most scientific approach to the problem but the results speak for themselves! I've fired 1200 BBs now without a single jam or double feed! Yay! I can hit a shoe box 120 times in 3.7seconds at 25yrds! Me thinks the feed system is working rather well for now, I'm almost put off changing the barrel back when the Prometheus bits arrive but if I can achieve results like this with a £20 barrel just imagine...

Fair point! I swapped out the Prometheus barrel for the crappy Element 6.04 and changed the cylinder head and nozzle, re shimmed and re built the gearbox and canged the black shark rubber for the clear and BOOM!

They do indeed appear to be 'the shit'. But not reinforced.

Eureka! I have identified the problem (fingers crossed!) It's the cylinder head nozzle, its split right down the middle and its chewing up and misaligning the air seal nozzle. I noticed black shavings in the barrel when i cleaned it. Now that I'm looking closer I have also noted that the cylinder isn't sitting square in the gearbox. Can anyone recommend a cnc machined, reinforced 9mm v2 box? Preferably with a quick change spring guide.

I'm starting to agree with you Ian, I don't know how long these loose bore barrels ha e been around but I can't find much in the way of reference material on testing and results, even on Airsoft Mechanics. As you point out the barrel's performance on the bench doesnt necessarily suggest results that could be replicated in the field. But I am willing to keep investigating and trying any suggestions, I have been given a thesis on ballistics to read so I may be gone sometime! Anyway I'm starting to think that the gearbox may be part of the issue as the resting place of the gear and there fore the nozzle allows for the next BB in the hop to sit in such a way that when the nozzle moves forward it is pushed up and mis feeds/folds the upper edge of the hop rubber in trapping the BB. So I'll try a range of products I've found specifically for the barrel and probably strip the gearbox again to make sure I haven't missed anything obvious!

There is a delayer on the sector gear but its a small baring rather than a chip. I'I've hdd some encouraging results today using modified shark rubber and thread locking the barrel in place in the hop unit. Firing through the inner barrel when not installed in the outer provides fantastically consistent results, however when the whole gun is assembled I sometimes get 1 BB per 2 pulls of the trigger. Occasionally BBs roll out of the barrel and in full auto I have noticed that sometimes when burst firing one third of BBs fly straight for 30+ yards another third spin high and left at 20yrds and a third drop left. She is 40 - 50% consistent over the last 1000 BBs I have managed to fire, so a big improvement on a few shattered fragments!

Good stuff, you would have thought that the tappet plate spring would be strong enough to feed the bb but obviously not. Glad someone else has had the same issue. The barrel came with the blue/soft rubber so god knows how bad the red would be. I've even got an uprated spring set in the gearbox.

Tbh I think even the 6.04 was too tight, I would occasionally get bbs stacking up in the barrel during full auto firing and when burst firing the first bb would fly straight and true but the second would drop low left and the third would fly straight. Plus 25yrds range is useless. The idea behind the 6.2mm barrel is to create flow around the bb to guide it down the barrel rather than force it down on a cushion as with tight bore barrels. The chamber that fits on the end of the Prometheus barrel has 3 nubs at the bottom and the hop nub protruding from the top to centralise the bb in the barrel. When I've loaded bbs manually the result has been spectacular to say the very least! Range is vastly improved to the point that my garden is no longer long enough to see when the bb's trajectory is overcome by the top spin. Accuracy is 100% (so far) at 25yrds with gun clamped in a vice, 1.5" groups! So I don't think its the barrel, I can't emphasise enough how impressed I am with its performance. Something is stopping the bb before it gets past the rubber collar. Is it the angle of the rubber? Where is the angle of the rubber measured from?

Its not a 6.02 it's a 6.2mm very loose, highly polished, Delta Strike type nub aperture. I'm going to cut the shark rubber to fit the barrel, it's much softer with a smaller collar. So how does the angle of the rubber affect the bb as it's pushed in to the hop chamber?

Madbull Ultimate Hop + Element H Nub + black Shark rubber + Element 6.04 x 248mm barrel + Ultimate airseal nozzle = vicious rof + adequate accuracy at 30yrd However! Madbull Ultimate Hop + Element H Nub + Prometheus Delta strike blue Rubber + Prometheus Delta Strike 6.2 x 275.5mm barrel + Ultimate airseal nozzle = viciously vicious rof however only occasionally actually firing and mostly shattered bb fragments. The bbs seem to be getting stuck in the hop and they are being broken by the nozzle. Its easy to push a bb through the collar of the hop rubber when the gun is disassembled but the nozzle cannot when the gun is assembled. This is getting frustrating now as its a parts gun, 6 months in the making and its so close to realisation.
