I have an all metal green gas WELL MAC11 (G12)

So you didn't get a magazine with it?

Yep

NOOOOOOOOOoooooooooooo............

JG do some pretty good MP5 models for decent prices and CYMA have metal uppers which are a bit more (if you can find one) Obviously something got chewed up so best not to use it until you figure out where the plastic came from and where the slippage is. Assuming you've already checked the gears have no wear and all the teeth are good on the piston, I would check the bushings and motor pinion gear. Are you using 11.1v Li-Po by any chance?

Could be part of the hop rubber? The first concern is why 5 BBs got stuck in the barrel. Hop set too high? You'll have to open it up at some point. Plenty of videos on YT to guide you. Its not very hard to get into a GBBR

We just go by general experience. Saves a lot of time. Until he defines his needs... Some people do a bit of research before asking questions but asking about an Inokatsu is not a great start.

Its true that it depends what he wants it for but that 'cookie cutter' response comes from years of the forum seeing people waste money on toys only to be disappointed with the experience and sell them soon afterwards. Gas guns do need a certain amount of experience and maintenance to get the most out of them. For home use is fine but for gaming they're very limiting to the inexperienced. @Johnelliott Look at WE, GHK, Tokyo Marui for various price levels of gas rifles.

What obscure information did you find to make you want an Inokatsu??? You're unlikely to find one, even less likely to find extra mags and even less likely to find spares... Read a bit of the forum for views on first toys to get ?

It may be coincidence but this is the only site where I've been hit (in the eyebrow above my eyepro) that actually drew blood. It was a 10m shot from a pistol (probably Co2) Pistols don't generally get tested at sites I know but Co2 ones are not allowed.

I'm not a peasant I'm a serf ? Wow, this thread has definitively come off the rails and into a ravine.

The answer is out there... ....waaaaaay out there ?

These statements shows you're clearly missing some crucial physics knowledge to understand the difference between BBs with Magnus effect versus an axial spinning projectile.

Yes, as long as you are at an official airsoft site or your own private land. The rifle must not be seen by the public.

Personally I don't think BFGs or pyro should be louder than a 209 primer. Definitely not indoors. There's no need to go louder than that as everyone in the 'kill' zone will definitely hear it. Blank firing guns at airsoft events may add to immersion for milsim games but not necessary for general game days. I think UK has more noise restrictions than the US sites. I'm sure there would be resident complaints if sites had constant semi and auto blank fire.

Yeah, I already know that (shocker) I'm talking on Earth... ...and its funny that the same isn't true for airsoft BBs because of the magnus effect. With the power of a sniper rifle its interesting that the bullet still drops at the same speed.

Here's an interesting gun fact which still intrigues me. If you fire a canon, rifle or pistol perfectly horizontally over a flat surface and drop an equal projectile at the same moment, they will both hit the ground at the same time. ?

Airsoft BBs use the magnus effect to fly straight so the backspin influences the distance a BB can fly. Unlike a real bullet, the higher speed of an airsoft fired BB does not necessarily equal longer range. The speed and weight must be perfectly matched to its backspin.

I don't even know what we're discussing anymore... ?

Yeah, I think everything got confused by referring to the video as an example of lower velocity = more energy into target which ONLY applies to hollow point spin stabilized projectiles. Saying that lower energy = lower velocity or heavier projectile = lower velocity is just following the formula so not in contention. Are we all happy? ?

Its a bit more complicated than that with airsoft BBs. Look up 'Joule Creep' but... Yes, a heavier BB will go slower and possibly further because its less affected by wind but that's nothing to do with what the video is showing.

I believe what the video shows is the guy finding the best energy/speed for the hollow point to open fully to its maximum without over deforming. The higher speed/energy caused the bullet to deform too much (hollow point folding over itself or tearing the rim off completely) resulting in a smaller cross sectional area therefore higher penetration. Again, this has no relevance to BBs

Perhaps I misunderstood your original point but if you're saying less speed equals more energy at the target then you've got something wrong there.

BBs don't deform on impact so the energy dissipation is not equivalent to hollow point bullet dynamics. Energy dissipation is proportional to projectile cross section area which is why hollow points dump all the energy so quickly. Energy = 1/2mv² Where m=mass and v=velocity Because it doesn't deform the energy dissipation of a BB will not change so lowering v will result in less energy at the target.

I don't think the video has any relevance to BB ballistics. First off he's using hollow points which don't have an equivalence in airsoft. What he's 'discovering' is the well understood projectile speed vs impact damage trade-off. This is the fundamental dilemma between the two most common military rounds. Slower 7.62 will do more damage to un armoured target but less penetration to armoured ones. Higher speed 5.56 has more penetrating ability for armoured targets but less damage to unarmoured ones. But none of this applies to BBs using the magnus effect.
