Hey guys,

I recently picked up an SRC HK416 Gen 3 Pro (thanks Ken) and overall it's a really excellent gun. After swapping the spring, I've gamed it a few times and have had no real issues with its operation.

That said, my wife recently picked up a CA G36C (also a nice gun) and when comparing the two, one thing is fairly obvious: I'm not getting a lot of hop out of the 416.

I always suspected something here as adjusting the hop-up even to the entirely on position made only a minor difference to the BB trajectories and I can never get the adjustment far enough that the BBs shoot up (or even as flat as I think they ought to).

I should note that the gun shoots consistently, just looking for a flatter trajectory with a bit more range (which the CA G36C seems to achieve better). Note also that I've tried a few different brands and weights of BBs and while the heavier ones obviously shoot somewhat flatter, there's no really noticeable difference in the hop between them. I think most of them have been 5.95 +/- 0.01's though, so perhaps 5.98's would get more hop in this gun?

Does anyone have experience with SRC Gen 3 hop-up units? Is this a normal problem? Anything I can do to make it operate better? Is there any way that I could have reinstalled it incorrectly (after doing the spring change) that would cause it to not hop, but otherwise operate normally (seems like a long shot)?

Please feel free to move this to the "upgrades and modifications" section if that's more appropriate. I couldn't really decide where this belonged...

Thanks in advance,
Andrew
