Have ideas on fixes?

It's a pretty common problem I've seen with plastic slide Hi-Capa 4.3's. Essentially, what's happening, is the slide is cycling so fast, that when it chambers the next round, it actually does it so fast that the BB pops past the retention nub in the hop up bucking. If it's pushed past that nub, then nothing will hold the round in place and it starts to roll out of the barrel on its own.
Light weight blowback units are meant to specifically speed up the cycle rate, so it makes the problem worse. Installing shock buffers, enhanced recoil springs, or short stroking will all attribute to this problem at all.
The default Marui OEM hop up rubber is sticky enough to work for what it was meant to do, but when you start changing the specs, it just won't be able to keep up. Combine a bit of silicone oil in your gas, and the friction coefficient drops even more. Even after soaking the rubber in dish soap, scrubbing it, degreasing it, and trying again, it just doesn't seem to work well.
The best solution I've found is to upgrade to a stickier hop up rubber. I personally recommend the Nine Ball hop up rubber. Doing the swap has solved this problem in 100% of the scenarios I've seen this issue.
