Fap or crap? Just received, looks solid but what are the gains?

They are extremely high quality, but far from needed at all. Stock parts last forever.

Just noticed that after replacing only the bolt set, trigger got really hard to pull. I know it will help me with high pressure-low volume setting (presumably best option to get high FPS with shot to shot consistency) but it also makes it difficult when shooting. I’ll replace the rest of the parts and decide what stays vs what doesn’t.

The only way I see the bolt kit affecting trigger pull is if it's a little thicker than oem's... so I would definitely recommend installing the other parts first (specially the sear and trigger) and see where to go from there.

Trigger is adjustable in weight and pull, so just play around with those little screws until you hit the sweet spot.

Since you're talking about high pressure, low volume... Are you running HPA or something? I would definitely advice against it. This gun is ridiculously consistent just on propane / map pro after fine tunning the power adjustment wheel and about a hundred rounds of wear-in. I'm talking springer-like consistency. And expanding gases always tend to creep more than HPA, so you won't see any benefit from using HPA and actually limit the max range.

Not talking about HPA, I’ve bought this rifle for its consistency on GG, just read opinions that it’s always better for consistency if the volume is low and compensated by pressure - that I can achieve with stronger piston spring. I will spend some time on fine tuning of course.

I’ve installed all the parts today, lubed and tuned the trigger to be almost as light as possible - it works, smooth and easy. I’m really impressed by the quality of this rifle. Also, a shout out to WII TECH, their parts are rock solid, great quality and designed better than OEM (I also got Marui 1911 aluminum cylinder set from them - kicks ass like hell!).

I only need to get one or two more mags and I’m good to go.

I’ve finally found 2 additional mags and was able to field the rifle once. After installing Wii Tech upgrades the rifle shoots within 500-650fps (regulation range) due to 170% hammer spring and the upgraded hammer itself that is a bit longer than stock. Unfortunately those upgrades made the FPS inconsistent AF. The first shot is 600fps, second 580 and then few following ones 550, then it drops to 520 as last shot. And all that with the adjustment screw almost all the way in. I’ve decided to go back to stock hammer set and will post results once done as my gut feeling is that too much force on the release valve produces too much gas output to be digested by the system.

I was able to hit a torso size target at around 90m (0.49 Novritsch Bbs) which is impressive IMHO but since the FPS inconsistency is too high it is hard to repeat results (and adjust the hop up in the first place).

So I went back to the stock hammer set and still was able get 580fps at 0.2g. I also reinstalled the Autobot bucking and did Teflon fix around it. The airtightness seems to be better now as I did a test by blowing into the inner barrel (while closing the gas entry port) and no air seem to leak anywhere. I’m getting around 570-580fps so still some room for improvement but it’s far better than was before. Not sure what else should I do. I’m already using silicon free Puff Dino GG (or mapp pro).

Hi there!

Do you think that 3 magazines are enough for a game?

Thanks!
