Guest JinxDuh Posted June 4, 2024 Posted June 4, 2024 (edited) Considering replacing the cylinder assembly and trying that, but at the same time I don’t want to keep spending on a project ? Maple leaf rubber with standard barrel and I’m getting this constantly with the hop arm all the way forwards ? Edit: Didn’t realise how “cheap” replacement parts would be. Poor ak2m4, he’s had like 4 sporadic orders from me this week already, and it’s only Tuesday! ? Edited June 4, 2024 by JinxDuh
Supporters Lozart Posted June 4, 2024 Supporters Posted June 4, 2024 I meant, is it a ported cylinder at all? That would explain why you're losing so much pressure.

Yep, I'd look at changing that to either one with just a notch at the very back or one without a vent at all.

I reckon the vent in your current one is too far forward so it'll limit the max FPS you're going to achieve. Worth a try at least!

Worth a try at least! It never even crossed my mind to be honest - Hopefully this'll solve my issues. Definitely a fun learning experience though!
Colin Allen Posted June 4, 2024 Posted June 4, 2024 Have you tried the paper test on the feed tube to see if there is an air loss between the nozzle and the hop rubber?

gavinkempsell Posted June 4, 2024 Posted June 4, 2024 (edited) Got some bits for my Scar-H on it's way, if I order some other bits I'll give you shout (I'm old & might forget tho). Just had a look at the spares & there's not much for the L85... magazine catch happens to be one listed, might be a common issue???? Edited June 4, 2024 by gavinkempsell

From what I’ve seen/experienced the mag catch on the WE stuff does tend to wear really fast
Guest JinxDuh Posted June 6, 2024 Posted June 6, 2024 New parts from Ak2m4 came in this morning, fitted the new cylinder (full seal) etc and all okay. The nozzle doesn’t fully reach the hop up rubber still (I did however buy a spare longer nozzle just in case) On chrono I was getting 1.36 joules roughly (.25g bb’s) so about 355 (I think. I’ve forgotten ?) Still not 100% perfect, but I’m going to run it this weekend and see if it’s shooting nicely or definitely needs the new nozzle. Thanks everybody for their help so far!
