well i do have a little question on a part being compatable with my gun. i want to know if the check it 15* assault block is compatable with the shutter. and if it would be a good mod for the gun. they say it has higher flow...will this effect my efficiency or the amount of air used?GBRudy16 said:almost all the spyders are the same as far as internals and performance goes. So the name of the gun pretty much doesn't matter. It just tells us if its electronic or not. But congrats on your purchase and if you have any questions at all this is the place for em.
