Nice! What sort of rubber did you use for this mod?

I used a tubing from a Lab at my work place. Part is call tygon r-3603 tubing. It works great so far. You have to cut and mod it to fit. Then file it down if theres to much hop.

The wall is flush with the ring and its pin in like the stock one. I also add a drop of super glue to keep it from moving.

I've been thinking about getting a better hop on my CTW (when I get it back), as the hop on the PTW/CTW seems a little lacking.

I was on the Systema forum and I saw a good idea (similar to above), and I thought that I woudl share. Here is a link

And some pictures,

Interesting idea as it gives a good surface area to help create backspin - keep us posted Joe.

will do mate, ive not had much enthusiasm after work lately but ill see what happens lol, will be more of a concave design though as the flat hop is a bastard for jams, concave is more forgiving and creates a more even spin.

Almost the same setup as mines, but mines has a curve and more contact on the bb. Im using .30 bb 300ft plus at 360fps.

Hi Guys
How we doing, sorry there's no introduction section so thought I'd say hi to all in my post!
Have had a m4a1 team alpha, up and running all sweet st the mo. had its first proper game with it at f&o's the acadamy on Sunday just gone.
While I'm happy with it at the moment, I like to tinker with things...



Thought I'd post my attempt up at a r-hop stylee:


The nub itself is curved to the same shape as the BB, I've worked the rear of the nub (facing away from barrel) so that the opening is slightly larger for about a mm, just to prevent any jams before the nub. (as MDodd said the adjustment needs to be minute, so I've microcalipered it so with the grub screwed at least 50% in its about 6.05mm gap,I need to measure how much adjustment I can get from that. I'm aiming for about 5.95mm gap at max)
Since the picture, I've reduced the width of the nub and put a hole in the nub so the the pin can go through. A couple more hours work later and I should be able to get it in and test it.
Hopefully want to get it up and running for this Sunday's game.
(will take spare standard rollers if it turns out to be an epic fail!)

You sound suprised......CTW's are the future of Training Weapons!!!

Yes they are not perfect, but nor is a PTW...... BUT they are less than 50% of the cost and if we all work together in the way the PTW forums have done then were on to a winner!!!!

All we need now is a 'CTW Tackleberry'......

cheers

Yes its true. Spent memorial day at Lion claw and I had people on my squad asking what I did to my gun to get that kind of range. Basically I was out ranging sniper that was on my squad. Very Happy

300 Feet is impressive, but if you are doing 360 FPS on a .30bb that is equal to around 442 FPS with a .2 bb and is 1.85 Joules energy wise , so range sounds about right.

I've managed to put the hop adjuster back together with the flat hop in place:


It's all set and ready to have a proper range test now. I had a quick play in my garden to make sure it does not jam, veer well off or not work at all, and it seems positive do far.
Over hops a .2g unless it's adjusted to the point nub is literally smelling the bb. With a .25 it hops it well. I even threw the gold cylinder in and tried some .36's which had a nice consistent flight path.
I'll post up results of how it performs against other guns on Sunday and will take a tape measure and see what kinda distance it's getting

Cheers Joe, it good to actually have time to do a few bits and bobs like this now works settled and Im not doing silly hours a week!

One of the slices I've made tho on the right is slightly askew, I'll recut the nub after this one just to make sure there's no movement.
Plus I want to check what the material is looking like after a a few games. Don't want it to wear out too quick. The other materials I have are s bit softer. The HS5 nubs are not thick enough to fit, but if this material fails, I could try glueing a HS5 nub on to a bit of buffer material and see if that holds up

Already have, works very well,but ,as we have fps limits of 330 fps max for AEG , I kind of do all my testing at that level. Control is the key to long contact patch.


Just sending a few of these out today, with a few other items.
