Doesn't KNS make a pin for the sear?

The gas opperated airsoft guns fire control groups work the same way as the guns they copy.

I have a realistic airsoft gun. The lower receiver is identical to a real m-16's. and I have had problems with the FCG pins walking out, so I used   KNS kit, but the auto sear pin still walks out. Anything I can do about that?

Like paintball without the paint, the propane-powered airsoft guns are designed to shoot quarter-inch plastic pellets and are generally used for recreation or in military and law enforcement training.

When the ATF seized a shipment of 30 of these guns in October from a port in Tacoma, Wash., it said they could be “readily convertible” to machine guns.

with “minimal work,” because its bottom half, or “receiver,” is so similar to an AR-15's.

To make the airsoft receiver function just like an AR-15’s, Gonnuscio said, “All you have to do is drill one hole.”

The cost of buying the Taiwan-made airsoft gun and all the parts needed to convert it to an AR-15 comes to roughly $1,100 –– more than the cost of some real AR-15s. But someone who can’t clear a background check or has been refused a gun for any other reason could use this method to make his own lethal weapon, Gonnuscio said.

Making it into a machine gun, he said, would require yet another conversion, and the makeshift gun would likely be able to fire only 15-20 rounds before it stopped working due to the pressure it would have to withstand while firing in an automatic fashion.

Ok it's time we clear up some things about these airsoft guns and make sure everyone knows just what is going on here.

The 30 guns siezed by the ATF are WETTI M4 GBB replicas. 'GBB' standing for "Gas Blow Back", describing the guns power source and method of operation. The WE M4 is just one of many different GBB M4's on the market today. The irony of this whole situation apparent to anyone who knows anything about these airsoft guns... is that the WE M4 is the least accurate replica of the M4 GBB's available.

Back in '07 a photo comparison was made between the WE, Inokatsu, and WA brand M4 GBB's alongside a real Colt M4 to show how 'real' these replicas are. Take a look:




Inokatsu matches up pretty well to the real deal right? Nope, looks can be deceiving. The Inokatsu lower receiver is actually 2mm longer than the real one and is incapable of accepting real upper receivers. Still, the similarities are impressive.. take special note of the hammer location.

Now lets look at the Inokatsu compared to the WE (middle of the group.) Notice anything?




Do you see it? The hammer position and location of the WE is completely off, and incapable of striking the firing pin of any AR bolt.

What's more, is the WE receiver is actually fake. There is no third hole drilled in the WE receiver... or first or second hole for that matter. That's because the WE airsoft GBB uses a drop in trigger pack that is of completley different design to any AR fire control group.

The hammer pin? Not an actual hammer pin. The auto sear pin? Not a hole either. About the only thing holding these parts together are the screws you see behind the bolt stop.

You can see the pack in the previousphotos, stripped away it looks like this:



This pack is incapable of being inserted into any AR-15 or M-16 type lower receiver. And even if it was, it is completely unable to function.



This whole ordeal is patently absurd. I might have some understanding if the ATF chose to investigate the WA, Inokatsu, or Prime type GBB guns... but the WE? Just shows how clueless they truly are.

They should move the tech people over to examiners. =)
