When priming the raider, the darts tend to sit up in front of the bolt. People have found that if they push their darts into the bolt manually, the dart will fly further.

This is because the dart tooth starts to move down when it is in contact with the bolt sled. There is a small arm at the bottom that pushes the dart tooth down. If you trim these two pieces down, they won't make contact until the priming sequence is near the end and pushes the dart further into the bolt rather than having it half in the bolt, half in the chamber.

Hopefully this picture will help.

This is the dart tooth and the arm on the bolt sled.



For reference, here is a picture from the raider over haul thread (thanks SPV999).



One thing to note, be careful how much you trim off the dart tooth. Trimming too much or at too steep an angle won't allow the top of the dart tooth to clear the bottom of the chamber tube. In my modification, the top is just about flush with the chamber. So make sure to try and keep the same angles.

Enjoy!

So how much farther does the dart go in? It would have to stop once the front of the barrel made contact with the tothe anyway, so I wouldn't think it goes in much farther.

For me, before this mod, the darts were going into the bolt a little more than half way. The dart will stop being pushed into the bolt when the tooth goes down, with this mod, the dart is pushed all the way into the bolt. It's not much further on the dart, but it definitely made a difference giving the darts a little more oomph.

Here's a quick video I took. I primed the raider up until the last moment before it locks. And you'll see that I push on the dart showing that I'll all the way back in the bolt. Sorry I didn't take a video or pics pre mod.

I`m pretty sure that this has been done for the recon since I have done it, but you made an excellent write-up though.

That's great, gonna definitely try this with my new Raider.

I didn't realize it stuck do far out. In that case, this should help a considerable-ish amount.

@xbox180: I was pretty sure it wasn't new, but I hadn't seen it before and I've never had a recon so this is my first look at the innards.

@Lt. Stefan: Yeah, it's not going to give you a significant boost, but every little bit helps.
