Hop-Up Bucking input

[league 4]

I had a 2GX in my G36 and now have it in an M4, and I never had a problem with it being inconsistent on auto. Granted, my G36 isn't shooting insanely fast (17 RPS), but it is putting out about average ROF.

I've just had better results with the Firefly design compared to a normal bucking with H/SCS nubs.

You're argument does sound reasonable though, but you need some proof, not just an opinion.

I could say the same about what you said.

I honestly expect the tightbore will have more effect on accuracy than the bucking/nub combination - but I also have heard many a report that the modified centering nubs still show a marked improvement.

I figure, for a 5 to 8 dollar investment, it's not going to hurt any to experiment with a new and interesting upgrade option.

Beyond that - I like the idea of a consistent 'shape' in the hop-up nub that supplies the benefit, rather than the pliable bucking features. The fingered design seems like it would, by it's very nature, not keep it's shape and thus lack some of the consistency.

I suspect that the shaped Nub-in-bucking design is more stable, but still would need some adjustment and tweaking to seat propperly for best effect.

Okay... well I did say that they shoot the same, I didn't say I think they shoot the same, but just to make you happy - here you go.

Range: 100 feet
Ammo: Bio-Shot .28g (Not the best, but what I had on hand)
Weather: Clear, sunny, slight cross-wind
AEG: Custom M4A1 - Details in my profile, but what you need to know: Promy 407mm TBB, KWA 2GX bucking
ROF: 20 RPS
FPS: 395+/-1 FPS
Shooting Position: Sitting with mono-pod. Again, not ideal, but it was what I had on hand at the time.

Semi - All but 2 shots hit:

Auto - All but 3 shots hit:


Since I wasn't using the best BB's and there was a slight cross-wind part of the time, there was some variation shot to shot (as seen in the pictures), but for a skirmish, that placement is quite adequate. Yes, this is a very crude test, but I think it gets my point across that the 2GX will work the same on both semi and auto.
