Well, that's yore opinion.

The stock barrel is fine, and replacing it won't have any effect on whether it's hopped properly or not: that's all down to the hop unit, rubber, and nub. Actually, stock everything should be fine, I suspect there's something wrong there. I'd again ask whether you're seeing any hop effect being applied, particularly with 0.28g. What's the hop set to?

Perun AB++ is well featured. You'll need to do a bit of soldering. You can also go with an optical mosfet inside the gearbox, I don't dabble in such sorcery though.

Not! Sure! If! Scam! But! Urgency! Suggest! Is! Scam!

Mags are key. None of mine will feed fast enough to satisfy stock JG G36 gears and ~1.1J spring, stone-age brushed Big Dragon M140, 11.1V 1.4Ah 30C, and slightly chonkier wiring with Perun AB++. I don't even know what rps it's running at because... well, the mags won't keep up. 5 round burst tends to get off 3 or 4 BBs. Once you start down the path of wankergunnery, you're going to keep running into one limit after another, so just dive in and solve the problems as you find them.

A mosfet with pre-cocking can do this. The X-ASR in your EDGE is only there for trigger protection, and can actually crap-out if you run a meatier motor (although I've only had that happen on 11.1v). The XT and 13:1 should help, as long as the battery can provide the amperage. As with most of airsoft uPgRaDeZ, the only way to really find out is to try it and see how well it works in your gun.

Nice of him to list the new, retail price of everything, I guess, but what does he expect to sell his used, warranty-free, condition-unknown items for? 🤷‍♂️

It's an older meme, but it checks out.

Muhammad McGlynn is an epic result from the RNG (Random Name Generator) though.

"I'll just step on that solid piece of moss an- [SPLOOSH]" Is it wrong to encourage rentals to perform... reconnaissance? As above, the colder (and drier) the better.

Non-magnified? Tube, or reflex? For non-magnified airsoft purposes, I get on fine with this style, which is sold in many many rebrandings from Amazon, eBay or AliExpress. I have two. They're light but solidly enough made, hold their zero over a day, are bright, and have a variety of reticules. Importantly, they're cheap enough not to cry over if you run without a sight protector and they get shot out. I really can't justify paying more than £20-£30 for a sight that's more consistent than the BB. What don't you like about your current sight?

I see you're pre-warming the mags, smart thinking.

Brushless is doubtless where we're going to end up, but I reckon the Big Dragon M140 is great value for money if you don't want to splurge that much. I'm running 2 of those (and an M160 in a DMR, but avoid the M120) and can't fault them. Running on 11.1V without any short stroking they eat BBs faster than my mags can feed them - I've just introduced some ROF reduction into one gun to calm it down.

Ahoy and welcome. I'm very sorry to hear that, and surprised too. My TAC-41 (gen 2, after they fixed the feed ramp) has been one of the very few airsoft purchases that's actually performed as advertised, right out of the box with just a spring change. Your energy is spot on 2.3J, so that's not the problem. It sounds like you're just very under-hopped. Do you actually see a difference in BB trajectory as you increase the hop? You should be able to send .28g BBs into low earth orbit with a decent amount of hop applied. If not, on the off chance that there's something damaged in there, you could try a Chub Nub, or replace the hop rubber, or waaaaait a second. When you say you've lubed it, including the "cup", have you put any sort of lube, like silicone oil, inside the barrel, hop unit, or inside the cylinder (or into the mags)? Is it possible that you've fouled the hop rubber with lubricant? And have you tried cleaning the hop rubber (and barrel) with a barrel cleaning rod and some paper towel / fabric patch, ideally with some isopropanol? Hang in there, it's a decent design and we should be able to figure this out.

Thus my first question. It's a bit like asking "What's the best dog?"
