Pollynator_bravo2 Posted Wednesday at 20:23 Share Posted Wednesday at 20:23 Evening all, so I have put together a quick build with some bits I had in the garage. I brought a max pro hop as the spare I had was bust. It’s running a max 21.25mm nozzle, maple leaf bucking. Compression from cylinder was fantastic no leaks. Inside the gb is a 13:1 gear set with a ASG 18k motor. I had two inner barrels that I’ve tried a brass 280mm and a steel 240mm I think. I am getting on the brass a range between 160 -280 and on the steel it never got past 150. 🤦♂️ there is no delay chip on as there wasn’t in this gb before. any ideas ?

Pollynator_bravo2 Posted Wednesday at 21:05 Author Share Posted Wednesday at 21:05 FYI was testing with 0.28g bbs. I grabbed a hi cap mag to test but normally I run mid cap pts epm1 mags so not sure if it’s a feed issue? Link to comment Share on other sites More sharing options...
ak2m4 Posted Wednesday at 21:22 Share Posted Wednesday at 21:22 What's the cylinder type, and what's the spring if you happen to know? Link to comment Share on other sites More sharing options...
The_Lord_Poncho Posted Wednesday at 23:27 Share Posted Wednesday at 23:27 With that much fps variation, potentially the bucking is folding at the lips? If you haven't already, maybe try a variety of different buckings, and ideally a different hop chamber at least to rule that out. Link to comment Share on other sites More sharing options...

Spring I think in m100. Cylinder I can’t remember the exact type but the port looks to be about two thirds down the cylinder 7 hours ago, The_Lord_Poncho said: With that much fps variation, potentially the bucking is folding at the lips?

Maple leaf have given me the occasional issue in the past however this one looked to be positioned correctly compared to those that have given me grief Link to comment Share on other sites More sharing options...
ak2m4 Posted Thursday at 09:42 Share Posted Thursday at 09:42 cylinder vents sounds right, as other said chop and change the chamber and/or the nozzle Link to comment Share on other sites More sharing options...
Colin Allen Posted Thursday at 21:58 Share Posted Thursday at 21:58 I would start by swapping out the hop unit or pairing it with a Maxx nozzle; the Maxx hop units are very picky and can be prone to power fluctuations if they are not happy.

Yeah it’s paired up with a Maxx nozzle as I had also read this so was a bit miffed when I ended up With problems tbh Link to comment Share on other sites More sharing options...
