I would suggest mancraft change the VSR cylinder head(The nozzle) to this shape:

It enters the hopup unit much easier.
I'll try modding one of them to fit, I'm just waiting for a 16mm drill bit in the mail.

Welcome to opposite world...
My stock cylinder head is thicker then the one from mancraft.
But the nozzle length is longer on the one from mancraft.
In all, the one from mancraft is about 0.75mm longer.

I modded a cylinder head from AirsoftPro to fit instead(16mm drill), as I like it more then a stock/mancraft.

BuMS, so you're using some standard cylinder head with mancraft kit? How did you mod it to make it work with the kit? Have you checked the performance yet?

Yes basically.
I just used a 16mm drill to widen it so it becomes hollow like the one from mancraft.
And the performance is the same, I haven't noticed any difference.

Just find a o-ring that fits the hole and you are fine.

It's a very low flow reg, so it might be too slow for you application(If you want to use it for anything semi auto).

I did have problems with my m700 running on this reg, but it might be the m700 causing the problem.
It's a long time since I tried it, so I might have better luck now.
That said, I'm waiting for a new manometer for my bottle.
