For as much as people seem to hate the Recon, it's been my favorite gun ever since I modded it.

Here's my rifle:







Effective range and accuracy is somewhere around 50 feet. Not the farthest ever, but pretty good, and probably within around a ~2' grouping. I got the briefcase for $2 at Goodwill, although I haven't figured out what PDR stands for yet.

I removed the AR's first and that improved the range, but not all that much. Adding the PVC trapped the air behind the dart better than the 7/8" barrels on the gun and improved it much more.

Actually, putting the gun back together again, it seems to be working now. I have NO idea what changed, but now it works better. Oh well. It shoots probably ~10 feet farther now though, if anyone else in interested in trying this mod. I used 5/8" OD, 1/2" ID PVC and cut it to five 3/4" lengths. Sanded those out on the inside with a dremel so the streamline darts would easily slip in and out, then superglued them in place.

Alright, I've taken the mechanism apart to have a better look at it. Are you talking about gluing these two pieces together?

Since you did nothing to the rotation mech, that might be the problem. I think you might have to glue the gear teeth together so that you can no longer rotate it (the barrels) by hand. Since that part is DESIGNED to skip on its own it might be skipping part-way due to the extra weight of the cpvc barrels causing it to over-rotate. It also looks like there is very little clearance between the CPVC and the rest of the shell so that might be causing a bit too much friction on the odd barrel that might be a tiny bit longer than the others. If the friction it generates is too much then the internal gears will skip making a "loud popping noise" and causing the barrels not to rotate. Try sanding down the front ends of the barrels slightly as well as glueing the internal gearing together, this SHOULD solve both problems.

I've sanded the CPVC down to the length of the gray plastic around it... there's a very small amount of clearance, but it shouldn't be touching. I'll check it again anyway though.

What do you mean exactly by "glue the gear teeth together"? Is there another thread that addresses this? I'm reluctant to jump into using glue on a moving part for fear of making it never work again.

@ChaosPropel: I agree about it not being too heavy, partly because of the bar supporting the barrel and partly because the CPVC weighs next to nothing, it's only a combined 3 3/4" worth of pipe, and it's sanded out on the inside.
