double shotting a hop rubber could be interesting, although i dont know how well it'd hold together. kinda like how they've done the c-clip for their vsr style rubbers.

it is the main advantage of the r-hop is having a softer patch compound but not entirely convinced it's all that relevant unless running higher energies (although at higher energies you need less spin too)

the CU chamber is very good, you won't be losing you barrel with one of those

It's more about breaking a clip every time I need to work on the hop/barrel.

My outer is stuck in place so I have to disassemble the thing while it's still inside the receiver

I'll see if I can find one in Europe, failing that, will order from GS.

Does it take the E&L magwell spacer?

ahh, that might be tricky then, the CU unit has a grub screw under the barrel to hold the c-clip in place and you kinda need to assemble it outside the gun for that.

it does take the e&l magwell spacer although it is a bit of a squeeze.

howd you get your outer stuck?
