I find the normal TM bucking perfoms well with a hnub. I have been messing around with shaving the bucking like your are doing a flat hop and using an element white hnub takes a bit of playing to get everything perfect but works really well. Just dont expect your bucking to last long.
Try firesupport never had a problem and I know a few people who have ordered from them and had no fps or any other issues. Also had them say when something is not worth doing when they could of taken my money and run. I only go abroad for things I cant get in the Uk. Uk retailers need to realise that people want good quality high spec parts not just Madbull crap
I wouldnt get either they are both a waste of money. If you want accuracy its mainly about your hop being set up right get a good bucking and nub combo and play around with your hop setting. If you want a good barrel for accuracy a tightbore is the wrong way to go. Get a decent 6.05 or 6.08 or even an orga widebore 6.13.
Quite a few people play at the mall on their own its a friendly site so you will always end up talking to someone. The marshalls are all decent people and the regulars usually help new players out with finding their way around. Just book in you won't regret it.
Sounds like a bargain for £14. What makes me laugh is how people say cheap barrels are bad then buy a madbull which I found to be worse than some stock barrels.
There is no competitor to PDI but every barrel is usless if you move or there is any wind so unless you are on a range or in a lab it doesn't really matter.
If you dont want to get second hand kit look at the ICS Cxp 16 polymer version its solid and quite cheap. I know a couple of people who have used them for over a year and never had any issues. They are easy to upgrade and accessories are easy to get,really good gun for the price.
You get a straighter cut using a cutting tool on a lathe than using a saw if you use a saw you would need to face off with the lathe saws very rarely cut true 90degrees.
You need a lathe to cut and crown it properly. Most airsoft shops will do it for you alternatively look for a local engineering workshop. Its only worth doing on expensive barrels it can be cheaper to buy a new one the right length.
Various companies do widebores for aeg's and people are getting good results with them. Im still not sure its worth the hassle. The Prommy 6.03 I tried didnt seem to make any difference over a stock barrel the pdi seemed to give me better groupings but thats just my opinion.
What spring you would need would depend on whats in the gun now and what fps you are looking to achieve. An Orga 6.23 dropped my a fps a lot. Needed a M120 to get my fps back up which meant strengthening the gearbox which wasn't cheap. PDI barrel you can just chuck in and wont change a thing other than the consistency of your shots. If you want to improve accuracy there is no one thing to change you have to look at the hop up most of all. If its a tm scar might be best just to leave it alone.
If you get the delta strike its a wide bore so you lose a lot of fps and have to upgrade quite a bit to get it back. If you want to use a widebore try the orga barrels they are much better you can get them from Socom Tactical. Personally I would get a PDI 6.05 best barrel I have tried you can get them from a site called airlab. Airlab is a small seller but has some very good upgrade parts and is very helpful and trustworthy. Prommy barrels are a bit over rated in my opinion.
I think I spoke to you about it in the safe room I said it might be your air nozzle all gunked up that could give you a bit of an increase. Didnt realise it was 80 fps though.
How does a gun randomly jump 80 fps. There are a few things that can increase fps fractionally but never heard of anything that can make it jump that much.
My mistake I didn't see the halo rifle. Your gun wasn't a crime against real steel
I thought it looked quite good and performed well too which is the most important thing.
Replace the end cap on the xcortech tracer with an aluminium disk as soon as you can. The plastic clip on one that is fitted is useless, mine got shot off the first time I used it.
