Tightbores for M4

Hi guys, im planning to do some kind of upgrade to my JG M4 S System. And i want to improve its accuracy, since it shoots at a decent 420 fps (i think). Is there any recommendations for tightbores? Like size? Brand? For what i have heard, DeepFire and Systema are pretty good brands on the market.

I also have a question, if i do get a tightbore, will there be anything else for the interals in my gun?? Will there be any replacing parts? Damage??

Thank you!!

I know another brand ,DB Customs. Also, I don't think that you will need to replace anything else if your just putting in a barrel.
Here's one that will probably work well: http://www.airsoftgi.com/product_info.php?cPath=31_55&products_id=3047

hmm ive heard some stuff about hop ups for some tightbores. Would you think i have to replace my JG M4 System stock hop up? Or leave it as it is?? I want to be sure if the hop up is compatable and good enough to handle the tightbore

I don't believe that you need to change your hop up because it is made specifically for the M4 ,but I don't know if that is only for the length. However, I'm pretty sure that it should be compatible with your JG M4 S System.

You don't have to replace any hop-up components for it to work, it'll just work better if you change out the bucking and nub.

The point of a tightbore is to increase accuracy, so you will want to change the hop-up "soft" parts for even better accuracy.

When it comes to hop up bucking's and TB's you will get a million answers as to which is best. But when it comes to "nubs" the H hop is without a doubt the best on the market:

well after looking at a couple tightbores, ive noticed they come in different sizes. Usually 6.01 and 6.04. Ive heard the 6.01 is very tight, and offers great accuracy, but the downside you have to clean the barrel everytime you play. Is it worth getting a 6.01 and cleaning it everytime? It may seem like a yes, but alot of silicon oil being used and running out and then buying more, seems like a waste of money.

^Easy solution, don't use silicone oil when you clean your barrel. It'll cause your accuracy to be crap anyways if you do.

THe performance difference between a .01 and a .04 is big. If you're going for max accuracy, get the .01

Yea, I do not know why everyone says spray silicone oil in your barrel and hop up. DONT' DO THAT. It screws up accuracy and is just plain pointles. 6.01 is the top dog when it comes to TB's, but you also have to make sure you use good quality BB's.

hmmm maybe i will go for .01. But how do you clean the barrel? All that build up can jam the gun

I say go with the 6.01mm because it is the most accurate and it isn't that hard to clean it after every use. I think DB customs is a really good brand so the one I linked before is pretty good so you can go with that ,but I would shop around first before buying it. Also, use highly polished good quality .25 bbs because it could be scratched easily if not polished and .25s will deliver good accuracy and range with your gun.

Just run the gun's cleaning rod with a patch on it until it comes out clean. Easy as pie.

I only give mine a nice oily cleaning every 10 games or so, then shoot about 200 rounds through it to get the oil back out.

When cleaning the barrel make sure that the hop up is all the way OFF. If not, you can rip your hop up.

I have a 6.03 madbull im my echo1 m4 fixed stock. I haven't used it yet, but is increases the performance by 15%-20%.

hmmm well i think i should get something alittle bigger. Cuz after thinking about it, 6.01 u have to clean, and can jam a bb easily. So i might get either a 6.04 but still thinking

get a 6.02 or 6.03 and keep it at the m4 length anything longer and you would have to change cylinders...

I use a 6.01 in several of my guns, and, even with my less than stellar cleaning record, I've never had a jam.

You just need to use good bbs (TSD, Killer Beez are all good), and occasionally give your barrel a quick wipe.

haha well in some cases im on a tight budget, and high quality bbs do cost alot.

If you're not going to run decent bbs through your gun, then don't even bother with a tightbore. It's like putting a turbo on your car and not running premium. Performance will suffer, or stuff will break, plain and simple.

I apologize if i offended you. Cause after you showed me the sites, i realized they cost about the same as the bbs i order from airsplat. I once saw hi quality bbs that cost like about $25 and it was for about 2000 rds

Yeah, they are not that expensive. My local store sells the polished G&G biodegradable ones in bags of 5000 for $20 which isn't that bad.

I have a 6.03 mm madbull tight bore in my E1 M733 and it made it a lot more accurate, and it rocks.
