Here is a picture-filled Raider review by SG Nerf
Disclaimer: Modifications may wear out or damage your blaster, I take no responsibility for people trying to do the same as me and breaking any part of their blaster.
I did a few mods to my Raider, the first was an Air Restrictor (AR) removal, by using the "pipe-cutter" method. I found that cutting slightly closer to the dip achieved a better result as the inside section then had more pipe to glue to (ask if your performing the mod and your not sure what I mean). I did not put any padding to protect the plunger tube.
I took off the safety catch which only lets you prime the blaster if there is a magazine in it, it was quite obvious what it was and was simple to remove. This lets me load darts into the gun by hand, by doing this I can push the darts in further than they would otherwise go.
I did a "power stock" mod for the blaster. This mod makes the blaster harder to prime but adds around 10' to the range. I used a maverick spring and ended up gluing it to the plunger tube to improve reliability. The mod involves cutting the end of the plunger tube cover off, gluing a short plastic piece to the plunger and putting a spring in between the plunger and inside of the stock (again if you have questions please ask). Here is a picture of what it looks like when I take the stock off and prime the blaster:

I will probably add to this post after I have some more Nerf war experience with the blaster.
