It's a little fuzzy but you got to see what I'm saying. All 3 of mine are the same.



bshantz...Your flash hider does look a little different though ;-)

So, anyone know where i can get replacement spacers for my Cradle velocity reducer?

[Thenooblord]

hardware store?

and guys, you know, if you simply leave the grub screw in you can spin the flash hider off WITH the brass tube....

Does anyone know where I can get a 6.01 inner TBB and outer for this gun? I would like the inner to be 250mm long, brass preferred. I also need a 265mm long outer barrel. I had a guy that I was able to get it from before buy he's not selling any more at this time.

Thx

It's not brass, but still an amazing barrel.

$40 for an aluminum madbull barrel doesn't sit right for me.

I've got the stainless steel CQB length RA-tech ones for $55

Mind linking it? And also, the madbull barrels are actually amazingly accurate. I've always had good luck with Madbull TBBs. Don't see anything wrong with an aluminum barrel. Sure it's softer, but if you keep it clean, it won't scratch.

There you go, it's in my section on the www.mb-airsoft.com boards

Amos - thanks I will order one from there.

Loco - thanks but Cansoft.biz has nothing. I have been talking to him on this already. The original one I had was a EDGI brass from him, pretty sweet but can't seem to find another.

I guess I will just modify a AEG for the outer. Can't seem to find anything out there.

Does anyone have any experience with the ra-tech hop up bucking compared to the stock one?

I have the Ra-tech bucking in mine. I have yet to thoroughly test the differences though cause my feeding lamp somehow cracked and needs to be replaced -_-.

But I did have a few skirmishs with it at Bragg Creek. The hopup effect seemed to increase by a crapton, but that's probably cause it was 1-4*C outside that day.

I gotta say, the gun performs quite decently in the cold.

I'll get some targets up for testing as soon as I get my new feeding lamp

How many rounds are you able to get off before noticing substantial cool down in the cold?

I could empty a whole mag in full auto and still have the bolt lock back if that's what you're wondering.
The ROF is definitely a lot lower in the cold, but it still works

Alright, I was just checking as I'll be running it as my primary, as it's my only gun, for a while...
