New inner barrel for hi capa (5inch) - IPSC

[Chairmanlao]

I'm in the market for a new inner barrel, i've done some research but now its time to hear some personal opinions.

This is for my TM 5.1 [Standard IPSC] - Don't care about the FPS, as long as I get a nice double tap / grouping

The first being the TK twist

I actually own it, but I wonder if there is anything "better".... I get about 1.25ish at 30ft with a double tap. I understand the TK twist is only for 330 and below? Otherwise it loses its benefit

I've heard 9ball

And then PDI and all that jazz. What do you personally like and why? Budget is <50 bucks

Thanks guys. Looking forward to hearing what you gotta say.

I noted that the real difference bitwin 6,03mm and 6,01mm is in the flyers..........
6,03 generate less flyers than 6,01 using the same bb , of course a very little difference in velocity 3-4mt\sec , it's better 6,01.
I Use PDI palsonite 6,01 and madbull 6,03, both 2 works good for my skill (not so good), but at same distance (9-10mt ) aiming with care I stay in 2,5mm (1")
Same use of yours (IPSC) and on 5" open and 5" standard.................1J limit

For best grouping, use the Nine Ball fixed chamber barrel. It deactivates hop up, thus, improving groupings by not introducing the side forces created by hop up systems.

These are best at 30 feet engagements (typical for Airsoft IPSC).

The Nine Ball barrel you linked is the standard barrel. That's not the one I'm referring to.

I run the TK hop twist inner barrel on mine. Works. I find it more consitentthan the other 01 barrels on the market. Though you can get better groupings with other barrels than using the TK Twist as ILLusion states above.

ILLusion did some tests on it which were quite interesting. here a read.

Hopefully up the groupings would be much better than 1.25 at 30... Hey at least its cheaper. lol

Yes, i've read all 9 pages of it months before I bought my first TK. Its a good barrel don't get me wrong... Just looking for something better (?)

Thanks guys.

If I remember right .... the 9ball barell have a sistem that works turning the barrel to adjust the tight of the rubber.
Any one have one and can show the working mode ???

It's seems very interesting !!!

I have one here. The more tight you screw the "hop up rubber", the more it compresses the o-ring, which tightens the grip on the BB.

Ok .......... If I can Ask............. this adjustment modify the point (referred in pressure ) of release of the bb.............(I think).........
what are the benefits of this solution?
Speed, power, or something else ?
Of course accuracy I've understand...............

Bye

Only accuracy.

By nature, the hop up system actually decreases accuracy. The purpose for the hop up system, is to increase range of the projectile. The off-axis forces it imparts on to the projectile affects its accuracy.

Many airsoft steel challenge pistols built in Japan and Hong Kong have the hop up system turned off or removed altogether.

Ok thanks Illusion

AirsoftGI had a special on the 9ball so I thought I would give it a shot. So far, its a piece of crap. No directions on how to install it, so Ive been guessing here and there. You have to screw it in pretty tight just so the hop up housing itself can close, from there the grip is over powering.
I really really really hope it is an user error and there is something wrong, but for now my original set up of the TK twist + 9ball is doing much much better.

Install it in the hop up first, and THEN adjust the tension by turning the barrel.

Yeah I figured that one out by accident about 4 hours in messing with it. By the end of the night from about 30ft the 9ball is starting to look better. Yet to really test it though.

Update for those who were interested in getting this barrel. It's taking a lot of fine tuning, and I am running out of options. Been using everything from .20 - .28. A double tap is looking better than before but accuracy is still not as good. And the double tap grouping is good till up about 20ft [almost in the same hole]
Anything over 25ft is looking bad, as well as the bb just drops. Not sure how much i need to turn to tighten...
